Understanding Insect Repellents: Types and Effectiveness

When venturing into the great outdoors, particularly for camping trips, insect repellents become an essential part of your gear. Not only do they prevent the annoyance of itchy bites, but they also provide crucial protection against insect-borne diseases like Lyme disease, West Nile virus, and various forms of encephalitis. In recent years, tick-borne diseases have more than doubled in the United States, with expanded risk areas, making proper protection more important than ever.

According to the Centers for Disease Control and Prevention (CDC), there are several EPA-approved active ingredients that are both safe and effective for repelling insects. Let's explore the primary types of insect repellents available in 2025:

DEET

Effectiveness: High (2-12 hours protection, depending on concentration)

Recommended Concentration: 20-30% for general use

Pros: Long-established safety record, excellent effectiveness against a wide variety of insects including mosquitoes and ticks

Cons: Oily feel, strong odor, can damage plastics and synthetic fabrics, watches, fishing line, cameras, and other plastic items

DEET has been the gold standard in insect repellents since the 1940s and remains highly effective. A product with 25% DEET can provide up to 10 hours of protection according to EPA-approved labels, though real-world testing suggests closer to 5 hours of actual protection time.

Picaridin

Effectiveness: High (up to 14 hours at 20% concentration)

Recommended Concentration: 20%

Pros: Non-greasy, minimal odor, doesn't damage plastics or synthetic fabrics, equally effective as DEET with fewer drawbacks

Cons: Slightly more expensive than some DEET products

Picaridin is a synthetic compound created in the 1980s that has proven to be as effective as DEET—sometimes even slightly more effective against mosquitoes and equally effective against ticks. It's been gaining popularity due to its pleasant feel and lack of damage to gear and clothing.

Permethrin

Effectiveness: Very high for ticks (up to 6 weeks or 6 washings on treated gear)

Recommended Concentration: 0.5%

Pros: Extremely effective against ticks (one study showed 73.6x reduction in tick bites), long-lasting protection for clothing and gear

Cons: Not for direct skin application, requires pre-treatment of clothing and gear, toxic to cats when wet

Unlike other repellents, permethrin is an insecticide that is applied to clothing, tents, and other gear rather than directly to the skin. It's particularly effective against ticks and should be used as a complement to skin-applied repellents, not as a replacement.

Oil of Lemon Eucalyptus (OLE)

Effectiveness: Moderate (shorter duration than DEET or picaridin)

Recommended Concentration: 30% OLE or PMD (its synthetic form)

Pros: Plant-based option, effective against mosquitoes and ticks

Cons: Strong odor, shorter protection time, not approved for children under 3 on some products

Oil of lemon eucalyptus (OLE) and its synthetic derivative PMD offer a plant-based alternative that has been proven effective, albeit for shorter durations than DEET or picaridin. It's a good option for those seeking a more natural approach without sacrificing too much efficacy.

IR3535

Effectiveness: Moderate (more effective against ticks than mosquitoes)

Recommended Concentration: 20%

Pros: Low toxicity profile, effective against ticks

Cons: Can damage plastics, often combined with sunscreen (not recommended)

IR3535 is less commonly known but is gaining recognition for its effectiveness, particularly against ticks. Like DEET, it can affect plastics, and it's often found in combination products with sunscreen, which isn't ideal since sunscreen needs to be applied more frequently than repellent.

Essential Oil-Based Repellents

Effectiveness: Low (very short duration)

Common Ingredients: Citronella, cedar oil, lemongrass, peppermint

Pros: Pleasant smell, all-natural ingredients

Cons: Very limited effectiveness, requires frequent reapplication

While many "natural" repellents market themselves as safer alternatives, they typically provide very limited protection. According to the Environmental Working Group (EWG), "While effectiveness varies, and there may be a few exceptions, most botanicals repel bugs for a short time, if at all."

When selecting an insect repellent for camping, it's important to understand that higher concentrations of active ingredients don't necessarily mean better protection—they often just extend the duration of effectiveness. For example, DEET's efficacy plateaus at around 50% concentration, with higher percentages simply offering longer protection times.

For most camping situations, experts recommend products with 20-30% DEET or 20% picaridin as they provide an optimal balance of effectiveness and duration without unnecessary chemical exposure. If you're in tick-heavy areas, combining a skin-applied repellent with permethrin-treated clothing and gear offers the most comprehensive protection.

As we look at specific product recommendations, keep in mind that the best repellent is the one that works for your specific needs and that you'll actually use consistently. A highly effective formula that you avoid applying due to smell or feel isn't protecting you at all!

Combined with picaridin on exposed skin, I haven't had a single tick attachment since implementing this system." - Quora user

5

Repel Plant-Based Lemon Eucalyptus Insect Repellent

★★★½☆
Check Price on Amazon

Active Ingredient: 30% Oil of Lemon Eucalyptus (OLE)

Protection Time: Up to 6 hours

Form: Pump spray

Why We Love It:

For those seeking a plant-based alternative to synthetic chemicals, Repel's Lemon Eucalyptus formula stands out as the most effective natural option. Unlike most essential oil repellents that provide minimal protection, this EPA-registered product offers meaningful defense against mosquitoes and ticks. It's a good compromise for those who prefer natural products but still need reliable protection.

Just be prepared for the strong scent!" - REI reviewer

When choosing from these top insect repellents, consider your specific needs. For most camping situations, our #1 pick (Sawyer Picaridin) offers the best overall performance with minimal drawbacks. If you're camping in tick-heavy areas, combine a skin-applied repellent with permethrin-treated clothing (#4) for maximum protection. Budget-conscious campers might prefer the Cutter Backwoods Dry (#3), while those seeking natural options should consider the Repel Lemon Eucalyptus (#5).

Remember that all of these products are effective when used correctly, and the best repellent is one that you'll consistently apply during your outdoor adventures.

Safety Considerations for Different User Groups

While insect repellents are generally safe when used as directed, there are important considerations for different user groups. Understanding these precautions will help you choose and use repellents appropriately for everyone in your camping party.

Children

Parents are understandably cautious about applying chemicals to their children's skin. Here are the key considerations:

  • The American Academy of Pediatrics (AAP) considers DEET safe for children over 2 months old, but recommends concentrations of no more than 30%.
  • Picaridin is approved by the EPA for use on children as young as 2 months.
  • Some Oil of Lemon Eucalyptus (OLE) products are not recommended for children under 3 years due to a lack of research.
  • Adults should apply repellent to their own hands first, then apply to children, avoiding eyes, mouth, and hands.
  • Do not apply repellent to children's hands (they often put them in their mouths).
  • Wash repellent off with soap and water when children return indoors.
  • For infants under 2 months, use physical barriers like mosquito netting over carriers instead of chemical repellents.

According to the Pediatrician Mom, "For most camping trips with children, a product containing 20% picaridin offers an excellent balance of safety and effectiveness, with fewer skin irritation concerns than DEET."

Pregnant Women

Pregnant women should take special precautions when using insect repellents:

  • The Environmental Working Group (EWG) recommends picaridin at a 20% concentration, or DEET at 20-30% concentration for pregnant women.
  • CDC recommends EPA-registered repellents for pregnant women, as the risk of mosquito-borne diseases generally outweighs potential risks from repellents.
  • Permethrin-treated clothing can provide additional protection without applying chemicals directly to skin.
  • Apply repellents in well-ventilated areas to minimize inhalation.
  • Wash treated skin with soap and water when protection is no longer needed.

The CDC states: "Pregnant women should take special care to avoid mosquito bites as certain viruses like Zika can cause birth defects. EPA-registered repellents, including those with DEET, picaridin, and IR3535, can be used by pregnant women when used as directed."

People with Sensitive Skin

Those with sensitive skin or allergies should exercise additional caution:

  • Perform a patch test with any new repellent by applying to a small area of skin and waiting 24 hours to check for reactions.
  • Picaridin generally causes less skin irritation than DEET, making it a good choice for sensitive individuals.
  • Avoid applying repellents to sunburned, cut, wounded, or irritated skin.
  • Consider using more physical barriers (long sleeves, pants) and permethrin-treated clothing to reduce the amount of repellent needed on skin.
  • Wash treated skin thoroughly when returning indoors.

According to Dr. Sonja Swiger, Associate Professor of Entomology at Texas A&M University: "If you have sensitive skin, picaridin-based repellents typically cause fewer reactions while maintaining excellent effectiveness against insects."

Pets Around Repellents

If you're camping with pets, additional considerations apply:

  • Never use human insect repellents on pets—they can be toxic if ingested during grooming.
  • Permethrin is highly toxic to cats when wet. Keep cats away from freshly treated clothing and gear until completely dry.
  • For dogs, veterinarian-approved repellents and preventatives are available specifically formulated for canine safety.
  • Keep repellent containers out of reach of pets, as chewing could release harmful chemicals.
  • Allow treated skin to dry completely before petting animals.

Veterinarians recommend: "If camping with pets, use separate pet-specific products recommended by your veterinarian. Human repellents, particularly those containing DEET or permethrin, can cause adverse reactions in pets if they lick treated skin or fur."

General Safety Tips for Everyone

  • Always read and follow the product label instructions carefully.
  • Apply repellents outdoors, in well-ventilated areas.
  • Use only on exposed skin and clothing—never under clothing.
  • Do not apply near food, to hands that will handle food, or to wounds or irritated skin.
  • Avoid spraying directly on face—apply to hands first, then carefully apply to face.
  • Apply sunscreen first, then insect repellent.
  • Don't use combination sunscreen/repellent products (different reapplication schedules).
  • Wash treated skin with soap and water when protection is no longer needed.
  • Store repellents out of reach of children and pets.
  • Wash treated clothing before wearing again.

Despite concerns about chemical repellents, the scientific consensus is that EPA-registered insect repellents are safe when used as directed, and their benefits in preventing insect-borne diseases generally outweigh potential risks. The Environmental Protection Agency (EPA) subjects these products to rigorous testing before approval, evaluating both effectiveness and safety.

For those concerned about DEET specifically, studies have found that serious adverse reactions are extremely rare. According to the EPA's findings, DEET does not present a health concern to the general population, including children, when used according to label instructions. Similarly, picaridin has demonstrated an excellent safety profile in testing.

As Joe Conlon, former technical advisor of the American Mosquito Control Association, notes: "What studies have been done on picaridin have found no connection between its use and any neurotoxicity, carcinogenicity, or mutagenicity." The same is true for properly used DEET products.

Remember that the primary goal of using repellents is to prevent potentially serious diseases transmitted by insects. When weighing safety concerns, consider that insect-borne illnesses like Lyme disease, West Nile virus, and others can have severe, long-lasting health consequences. Using repellents properly is an important preventative health measure for outdoor activities.

Natural Alternatives and DIY Solutions

While EPA-registered repellents containing DEET, picaridin, and oil of lemon eucalyptus provide the most reliable protection, some campers prefer to explore natural alternatives. It's important to note that most natural repellents offer significantly less protection than their synthetic counterparts, often lasting only 20-30 minutes before reapplication is needed. However, they can be useful as supplementary protection or in low-risk areas with minimal insect activity.

Essential Oils with Some Repellent Properties

Citronella Oil

Effectiveness: Moderate, short-lived (30-60 minutes)

Best Use: Supplementary protection in combination with other methods

One of the most well-known natural repellents, citronella can provide some protection against mosquitoes but requires frequent reapplication. Most effective when used in multiple forms simultaneously (candles, torches, personal spray).

Lemongrass Oil

Effectiveness: Moderate, short-lived (20-40 minutes)

Best Use: Personal spray in low-risk areas

Studies have shown lemongrass oil has some repellent properties against certain mosquito species. Its pleasant citrusy scent makes it more appealing than many synthetic options, though protection time is limited.

Peppermint Oil

Effectiveness: Low to moderate (20-30 minutes)

Best Use: Personal comfort, tent/campsite refreshing

The strong scent of peppermint can mask the human odors that attract mosquitoes and may repel some insects. It creates a cooling sensation on the skin and can help make outdoor spaces more comfortable.

Tea Tree Oil

Effectiveness: Low to moderate (15-30 minutes)

Best Use: Personal spray, especially for ticks

Tea tree oil has shown some effectiveness against ticks in particular. Creating a perimeter spray around your tent with tea tree oil solution may help create a barrier against crawling insects.

Lavender Oil

Effectiveness: Low (15-20 minutes)

Best Use: Personal comfort, sleep aid with some repellent benefit

The soothing scent of lavender provides minimal but measurable repellent effects. It's most effective when fresh lavender is burned in campfires, though a diluted spray can provide short-term relief from mosquitoes.

Eucalyptus Oil

Effectiveness: Low (except OLE, which is moderate to high)

Best Use: Personal spray, campsite perimeter

Regular eucalyptus oil provides minimal protection, but Oil of Lemon Eucalyptus (OLE) is EPA-registered and much more effective. Don't confuse standard eucalyptus oil with the more effective OLE products.

DIY Natural Repellent Recipe

For those interested in creating their own natural repellent, here's a recipe that combines several essential oils for improved effectiveness. Remember that this will still require frequent reapplication and doesn't provide the same level of protection as EPA-registered repellents.

Multi-Oil Natural Repellent Spray

Ingredients:

  • 10 drops citronella essential oil
  • 10 drops lemongrass essential oil
  • 10 drops peppermint essential oil
  • 5 drops tea tree essential oil
  • 5 drops cedarwood essential oil (optional)
  • 1/4 cup witch hazel or vodka
  • 1/4 cup distilled water
  • 1 tsp vegetable glycerin (optional, helps the oils mix with water)

Instructions:

  1. Add the witch hazel or vodka to a 4oz spray bottle
  2. Add all essential oils and glycerin if using
  3. Fill the remainder with distilled water
  4. Shake well before each use
  5. Apply every 15-30 minutes for continuous protection

Note: Always perform a patch test before applying extensively. Avoid applying near eyes, mouth, or sensitive areas. Not recommended for children under 3 years old.

Campfire Enhancements for Insect Protection

Campfires naturally help repel insects, and you can enhance this effect by adding certain materials. According to recent studies, these additions can increase the repellent properties of your campfire:

Herbs for the Campfire

  • Sage: Creates a strong smoke that repels mosquitoes and other flying insects
  • Rosemary: Produces aromatic smoke that masks human scents
  • Lavender: Adds pleasant aroma while discouraging insects
  • Mint: Particularly effective against flies and ants

Simply toss a handful of fresh or dried herbs onto the fire periodically to release their insect-repelling properties. While not as effective as chemical repellents, this can create a more comfortable zone around your campfire.

Other Natural Campsite Strategies

  • Citrus Peels: Burn dried orange, lemon, or grapefruit peels
  • Cedar Wood: Naturally repels many insects, especially moths
  • Pine Needles: Creates pungent smoke that deters flying insects
  • Coffee Grounds: Sprinkle used grounds around campsite perimeter

These methods work best in combination with personal repellents and are most effective in areas with moderate insect pressure. For heavy insect activity, rely primarily on proven EPA-registered repellents.

Important Note on Natural Repellents

While natural alternatives may appeal to those seeking to avoid synthetic chemicals, it's important to understand their limitations:

  • Protection time is significantly shorter (often 15-30 minutes vs. 4-12 hours for EPA-registered options)
  • Effectiveness varies widely based on individual body chemistry and insect species
  • Natural doesn't automatically mean safer—essential oils can cause skin irritation or allergic reactions
  • In areas with insect-borne diseases, the protection provided by natural repellents may be inadequate

The Environmental Working Group (EWG) cautions: "While effectiveness varies, and there may be a few exceptions, most botanicals repel bugs for a short time, if at all." In high-risk areas or for extended outdoor activities, EPA-registered repellents remain the most reliable choice.

For the best protection in moderate to high-risk areas, consider using natural methods as a supplementary layer of defense alongside EPA-registered repellents. For example, use picaridin on exposed skin, permethrin on clothing, and enhance your campsite with herbs in the fire and strategic placement of citronella candles or torches.

By combining multiple approaches, you can minimize chemical exposure while still maintaining adequate protection against potentially dangerous insect bites.

Application Tips for Maximum Protection

The effectiveness of any insect repellent depends not just on the active ingredient, but also on proper application. Even the best products can fail if applied incorrectly. Here are comprehensive guidelines to ensure you get maximum protection from your insect repellent during camping trips.

Proper Application Technique

Before Applying

  • Apply in open, well-ventilated areas to avoid inhaling spray
  • Apply sunscreen first, wait 15 minutes, then apply repellent
  • Shake the container well before use
  • Read product-specific instructions, as application varies by formulation

Skin Application

  • Apply a thin, even layer to all exposed skin
  • Hold spray bottles 4-6 inches from skin for even coverage
  • Don't spray directly onto face—spray on hands first, then apply to face
  • Avoid applying near eyes, mouth, cuts, wounds, or irritated skin
  • Don't apply under clothing—only on exposed skin or on top of clothing
  • Pay special attention to ankles, wrists, neck, and other thin-skinned areas mosquitoes prefer
  • For lotions, use just enough to cover skin with a thin layer

Clothing Application

  • Lightly spray outer layer of clothing, especially cuffs, collar, socks, and hat
  • Test on small, hidden area first to ensure fabric isn't damaged (especially with DEET)
  • Allow repellent to dry before wearing treated clothing
  • For maximum protection, use permethrin-treated clothing in addition to skin repellent

After Application

  • Wash hands thoroughly after application to avoid transferring to food or eyes
  • Don't touch or rub eyes until hands are washed
  • Reapply according to product instructions or after swimming/excessive sweating
  • Wash treated skin with soap and water when protection is no longer needed
  • Wash treated clothing separately before wearing again

Timing is Everything

When to apply repellent can significantly impact effectiveness:

  • Apply 15-20 minutes before exposure to allow proper distribution and activation
  • For picaridin and DEET sprays, protection begins almost immediately
  • For picaridin and DEET lotions, allow 20 minutes before full effectiveness
  • For permethrin clothing treatment, apply at least 2-4 hours before needed (time to dry)
  • Reapply according to product directions, not when you start getting bitten

Remember that humidity, temperature, and perspiration can affect how long repellents remain effective. In hot, humid conditions or during strenuous activity, you may need to reapply more frequently.

Common Application Mistakes

  • Under-application: Using too little repellent provides inadequate protection
  • Over-application: More isn't better—follow label instructions
  • Irregular coverage: Missing spots creates vulnerability
  • Applying to sweaty or wet skin: Reduces effectiveness and absorption
  • Applying over lotions or makeup: Can reduce effectiveness
  • Relying solely on repellent: Should be part of a comprehensive strategy
  • Applying under clothing: Wastes product and increases chemical exposure

Layered Protection Strategy

For maximum protection in high-risk areas, experts recommend a comprehensive, layered approach:

Step 1: Environmental Modifications

  • Choose camping sites away from standing water when possible
  • Set up in breezy areas—insects struggle in wind over 5 mph
  • Use a screened shelter for eating and relaxing
  • Eliminate standing water near campsite
  • Consider timing—avoid peak mosquito activity (dawn/dusk) when possible

Step 2: Physical Barriers

  • Wear light-colored, loose-fitting clothing
  • Choose long sleeves and pants when possible
  • Use permethrin-treated clothing for enhanced protection
  • Wear closed-toe shoes and socks (not sandals)
  • Consider a head net in extremely buggy conditions
  • Use a tent with intact mesh screens

Step 3: Chemical Protection

  • Apply permethrin to clothing, tent, and gear before trip
  • Use EPA-registered repellent on exposed skin
  • Consider spatial repellents like Thermacell for campsite perimeter
  • Use citronella candles, coils, or torches as supplemental protection
  • Reapply skin repellent according to label instructions

Repellent Application for Different Camping Activities

Day Hiking

  • Apply to exposed skin before leaving camp
  • Carry a small bottle for reapplication
  • Focus on ankles, wrists, and neck
  • Reapply after excessive sweating

Water Activities

  • Choose water-resistant formulations
  • Reapply after swimming or toweling
  • Apply more frequently in humid conditions
  • Allow to dry completely before water exposure

Evening Around Camp

  • Reapply at dusk (peak mosquito time)
  • Supplement with spatial repellents
  • Consider head nets if bugs are severe
  • Position yourself in campfire smoke

Remember that proper application is just as important as choosing the right repellent. By following these application guidelines and implementing a layered protection strategy, you can dramatically reduce your risk of insect bites and associated diseases during camping trips, allowing you to fully enjoy your outdoor experience.

As Dr. Sonja Swiger notes, "The use of these products provides protection to humans that cannot be achieved by anything else." Take the time to apply repellents correctly, and you'll reap the benefits of effective protection throughout your camping adventure.

My Experience: Field Testing in Various Environments

Over the past five years, I've personally tested dozens of insect repellents across a wide range of camping environments—from the humid, mosquito-infested Boundary Waters of Minnesota to the tick-heavy Appalachian Trail. These firsthand experiences have given me valuable insights beyond laboratory testing and manufacturer claims. Here's what I've learned from real-world use:

The Great DEET Transition

For years, I was a dedicated DEET user. Growing up camping in northern Minnesota, where mosquitoes can be thick enough to inhale, my parents always packed the highest concentration DEET products available. The smell became almost nostalgic—a sign that adventure was about to begin.

However, during a 10-day backcountry trip in 2020, I experienced firsthand the downsides of DEET when my 98% DEET spray leaked in my backpack. It melted part of my nylon rain jacket, damaged my watch band, and made the finish on my trekking poles tacky. While it certainly kept the bugs away, the damage to my gear was significant.

This experience prompted me to explore alternatives, and I began testing picaridin products. The transition wasn't immediate—I was skeptical that anything could match DEET's effectiveness in truly challenging conditions. But after side-by-side testing on several trips, I was convinced: 20% picaridin repellents provided comparable protection without damaging my gear.

Now, I primarily use Sawyer's 20% picaridin spray for most camping trips. The only exception is in extreme conditions where I might still use a DEET product, being extra careful with application and storage.

Permethrin: A Game-Changer for Tick Country

My most dramatic experience came after hiking a section of the Appalachian Trail in Pennsylvania—notorious for its high tick populations—in spring 2022. Despite using a 25% DEET spray, I found three attached ticks during my evening check. This concerning experience led me to research better tick prevention methods.

For my next hike in the same region, I pretreated all my clothing with Sawyer permethrin spray, carefully following the application instructions to saturate the fabric until damp. I also sprayed my backpack, tent, and even my trail runners. After allowing everything to dry completely, I hit the trail again, this time using picaridin on exposed skin.

The difference was remarkable. Over five days in the same tick-heavy region, I found numerous ticks crawling on my permethrin-treated clothing, but they were sluggish and soon fell off. Most importantly, I didn't find a single attached tick during my daily checks. This experience converted me into a firm believer in the permethrin + picaridin combination for tick protection.

I now maintain a dedicated set of "tick country clothes" that I retreat with permethrin at the beginning of each season and before any trips to high-risk areas. The time investment in pre-treating gear has paid off with peace of mind and protection.

Natural Products: Limited Success

I've tried numerous natural repellents over the years, particularly during shoulder seasons when insect pressure is lower. My experiences with these products have been mixed at best.

During a spring camping trip in Colorado's Front Range, I tested a popular essential oil-based repellent containing citronella, lemongrass, and cedar oils. In the cool, dry mountain air with moderate mosquito activity, it seemed to work reasonably well when first applied. However, within 30 minutes, I noticed mosquitoes landing on my arms again. Frequent reapplication (every 20-30 minutes) was necessary to maintain even modest protection.

I've had slightly better results with repellents containing Oil of Lemon Eucalyptus (OLE). During a fall camping trip in the Ozarks, Repel's Lemon Eucalyptus product provided about 3-4 hours of protection—significantly better than other natural options, though still not matching picaridin or DEET. The strong smell was polarizing among my camping group; some found it pleasant, while others complained it was overwhelming in the confined space of our evening campfire circle.

My conclusion on natural repellents: they have their place for short outdoor excursions in areas with low insect pressure, but I wouldn't rely on them for serious protection in high-risk environments or for extended outdoor activities.

Regional Effectiveness Variations

One fascinating pattern I've observed is how repellent effectiveness can vary significantly by region and insect species. What works brilliantly in one environment might perform differently elsewhere.

In the northern woods of Minnesota and Wisconsin, where large, aggressive woodland mosquitoes dominate, higher concentration DEET products (25-30%) and picaridin seem equally effective. However, in Florida's Everglades, I found picaridin slightly outperformed DEET against the smaller salt marsh mosquitoes prevalent there.

For desert camping in Arizona and Utah, where flies and gnats are often more problematic than mosquitoes, picaridin has been my clear preference. It seems particularly effective against the persistent face flies that can make desert camping miserable in certain seasons.

In tick country along the eastern seaboard, nothing has matched the effectiveness of permethrin-treated clothing combined with picaridin on exposed skin. This combination has proven reliable from the southern Appalachians all the way up to Maine's deep woods.

These regional variations highlight why there's no single "best" repellent for all situations. Your destination and the specific insects you'll encounter should inform your repellent choice.

Application Lessons Learned

Perhaps the most valuable insights from my field testing involve application techniques. Even the best repellent will fail if applied incorrectly, and I've learned this lesson the hard way.

During one particularly buggy camping trip in Michigan's Upper Peninsula, I hastily applied repellent before an evening fishing excursion. By skipping my ankles and only applying to my arms and neck, I created a vulnerability that mosquitoes quickly exploited. I ended up with dozens of bites around my ankles and lower legs, despite being well-protected elsewhere.

I've also learned that reapplication timing is crucial. Rather than waiting until I notice bites (too late!), I now set a reminder based on the expected protection time of my repellent. For picaridin, I typically reapply every 8-10 hours, regardless of whether I'm noticing insect activity. This proactive approach has significantly reduced "breakthrough" bites.

Another key lesson: spray pattern matters. After trying numerous bottles and formulations, I've found that pump sprays generally provide more controlled application than aerosols, especially around the face and neck. However, aerosols can be advantageous for quickly treating clothing or for reaching difficult areas like the middle of your back when camping solo.

Based on these real-world experiences across diverse environments, I've developed my current protection strategy: permethrin-treated clothing and gear as the foundation, 20% picaridin spray for exposed skin, and a Thermacell device for the campsite perimeter in high-pressure areas. This multi-layered approach has proven effective in virtually every camping environment I've encountered.

While laboratory testing and expert recommendations are valuable, nothing replaces firsthand experience in real camping conditions. My journey from DEET devotee to picaridin convert reflects both the evolution of available products and a better understanding of the balance between effectiveness, comfort, and gear compatibility.

Frequently Asked Questions

Is DEET dangerous for children?

The American Academy of Pediatrics considers DEET safe for children over 2 months old when used as directed, but recommends using concentrations of no more than 30%. Parents should apply the repellent to their own hands first, then transfer to the child, avoiding eyes, mouth, hands, and any irritated skin. After returning indoors, wash the treated skin with soap and water. For children under 2 months, use physical barriers like mosquito netting rather than chemical repellents.

Research has shown that serious adverse reactions to DEET are extremely rare, and no studies have demonstrated developmental issues with normal use. Many families may prefer picaridin-based repellents for children due to the milder odor and non-greasy feel, but both DEET and picaridin are considered safe when used properly.

How do I choose between DEET and picaridin?

Both DEET and picaridin provide excellent protection against mosquitoes and ticks when used at appropriate concentrations. Your choice might depend on personal preferences and specific needs:

Choose DEET if: you have a history of it working well for you, you need a widely available option that can be found in most stores, or you're on a tight budget (DEET products are often less expensive).

Choose picaridin if: you want a less greasy feel and minimal odor, you're concerned about damage to synthetic clothing or plastic gear, or you're looking for a repellent that's equally effective but with fewer aesthetic drawbacks.

Studies comparing 20% picaridin to comparable DEET concentrations have shown similar effectiveness, with some evidence suggesting picaridin may provide slightly longer protection. Both ingredients are EPA-approved and considered safe when used as directed.

Are higher concentrations of repellent more effective?

Higher concentrations of active ingredients primarily affect duration of protection rather than effectiveness. For example, DEET's repelling effects tend to plateau at around 50% concentration—higher percentages don't repel more insects but may provide longer protection.

For most camping situations, concentrations of 20-30% DEET or 20% picaridin offer an optimal balance of effectiveness and safety. These concentrations typically provide 6-12 hours of protection, which is sufficient for most camping activities with reasonable reapplication schedules.

Extremely high concentrations (like 98-100% DEET) are rarely necessary for typical camping and may increase the risk of side effects or damage to gear without providing meaningfully better protection. When choosing a repellent, consider duration needs rather than assuming higher percentages equate to better protection.

Can I use insect repellent and sunscreen together?

Yes, you can use both insect repellent and sunscreen, but proper application order matters. Always apply sunscreen first, allow it to absorb into your skin (about 15 minutes), and then apply insect repellent on top. This sequence ensures both products work effectively without interference.

Avoid using combination products that contain both sunscreen and repellent in a single formula. The problem with these products is that sunscreen should be reapplied every 2 hours, while repellents are typically effective for much longer. Using a combination product could result in either inadequate sun protection or unnecessary overexposure to repellent chemicals.

If you need to reapply sunscreen while wearing repellent, apply the sunscreen carefully over the repellent. After swimming or excessive sweating, you'll likely need to reapply both products, following the same sequence: sunscreen first, then repellent after the sunscreen dries.

What's the difference between repellent sprays, lotions, and wipes?

The primary differences between repellent formulations involve application method, protection duration, and convenience:

Sprays offer quick, easy application and can be applied to clothing as well as skin. Pump sprays provide more controlled application, while aerosols cover larger areas faster but with more potential for overspray. Sprays typically dry quickly and are ideal for quick reapplication during activities.

Lotions generally provide longer-lasting protection than comparable sprays (up to 14 hours for 20% picaridin lotions vs. 12 hours for sprays). They're less likely to evaporate quickly and can be precisely applied, making them good for face application or use with children. The downside is they take about 20 minutes to become fully effective and cannot be applied to clothing.

Wipes offer excellent portability and convenience for travel or quick application. They're TSA-friendly and provide good control for application around the face and neck. However, they generate more waste and may not cover large areas as efficiently as sprays.

All formulations can be effective when properly applied. Your choice might depend on specific needs: sprays for general use and clothing, lotions for extended protection, and wipes for travel convenience.

How does permethrin differ from other insect repellents?

Permethrin differs fundamentally from repellents like DEET and picaridin in several important ways:

Application target: Unlike DEET and picaridin, permethrin is not designed for direct skin application. Instead, it's applied to clothing, tents, backpacks, and other gear.

Mode of action: While DEET and picaridin repel insects by interfering with their ability to detect humans, permethrin actually kills ticks and mosquitoes on contact by attacking their nervous systems.

Duration: Permethrin provides much longer protection—up to 6 washings or 6 weeks on treated items—compared to the hours of protection from skin repellents.

Complementary use: Permethrin is designed to be used alongside skin repellents, not instead of them. The ideal protection system uses permethrin-treated clothing plus DEET or picaridin on exposed skin.

Studies have shown remarkable effectiveness against ticks in particular, with one finding that subjects wearing permethrin-treated footwear were 73.6 times less likely to have a tick bite than those with untreated shoes. For camping in tick-heavy areas, permethrin treatment of clothing and gear is one of the most effective preventative measures available.

Conclusion

Choosing the right insect repellent for your camping adventure is more than a matter of comfort—it's an important health consideration that can protect you from potentially serious insect-borne diseases. Throughout this guide, we've explored the science behind effective repellents, detailed reviews of the top products, and practical advice for maximum protection.

Based on extensive research and testing, the clear standout for most camping situations is Sawyer Products 20% Picaridin Insect Repellent, offering an optimal balance of effectiveness, comfort, and gear safety. Its non-greasy formula, minimal odor, and reliable protection against both mosquitoes and ticks make it the ideal choice for most campers.

For those camping in high-risk tick areas, adding Sawyer Permethrin Fabric Treatment to your protection strategy provides an exceptional additional layer of defense. The one-two punch of permethrin-treated clothing and picaridin on exposed skin represents the gold standard in comprehensive insect protection.

Remember that proper application is just as important as choosing the right product. Apply repellents in well-ventilated areas, use a thin layer on all exposed skin, reapply according to product instructions, and wash off when protection is no longer needed.

While natural alternatives may appeal to some campers, it's important to recognize their limitations. Products containing Oil of Lemon Eucalyptus (like our #5 pick, Repel Plant-Based Lemon Eucalyptus) offer the best protection among natural options, but still require more frequent reapplication than DEET or picaridin.

For families camping with children, both picaridin and DEET (at concentrations of 30% or less) are considered safe for children over 2 months old when used as directed. Parents might prefer picaridin's milder sensory profile, but either option provides reliable protection when properly applied.

Ultimately, the best insect repellent is one that you'll actually use consistently. Consider your specific needs, the environment you'll be camping in, and your personal preferences when making your selection. By taking insect protection seriously and implementing the strategies outlined in this guide, you can enjoy your camping adventures with fewer bites and greater peace of mind.

Don't let insects ruin your outdoor experience—with the right repellent properly applied, you can focus on the beauty and joy of camping rather than swatting, scratching, and worrying about bugs. Happy camping!
