| Active ingredient | 20% Picaridin |

Sawyer’s 20% Picaridin continuous spray is a family-friendly insect repellent intended for skin and clothing that targets mosquitoes, ticks, and biting flies. It is typically used before outdoor activities such as hiking, camping, backyard gatherings, or work around the yard by spraying clothes or exposed skin and letting it dry; the manufacturer recommends lotion for skin and spray for clothing to extend protection. Notable features include a 20% picaridin formula, fragrance-free and non-greasy feel, and claims of up to 12 hours protection against mosquitoes and ticks and up to 8 hours against biting flies and gnats. Because it does not damage plastics or synthetic coatings, it can be applied to gear like backpacks, sunglasses, and firearm finishes. The practical benefits are long-duration protection without the oily residue associated with some repellents and suitability for family use. Limitations are that sprays generally offer shorter skin duration than lotions and effectiveness can vary with sweating or heavy rain, so reapplication or pairing with permethrin-treated clothing may be needed for sustained protection in very wet or high-exposure conditions.
Best for: Buyers who want a reliable, low-odour repellent for day-long outdoor activities and prefer a spray that can be applied to clothing and gear as well as skin.
Less Ideal for: People who need the absolute longest single-application skin protection or who prefer a lotion texture for direct skin application.
- 20% picaridin formula gives long-duration protection against mosquitoes and ticks
- Non-greasy, fragrance-free spray that dries quickly and is comfortable on skin
- Safe to use on clothing and gear without damaging plastics or synthetic coatings
- Effective against a wide range of pests including biting flies, gnats, and chiggers
- Spray version provides shorter skin protection than the lotion form
- Performance can be reduced by heavy sweating or rain requiring reapplication
Verdict: A long-lasting, non-greasy spray repellent that protects against mosquitoes, ticks, and biting flies while being safe to use on clothing and outdoor gear.
Sawyer Premium Insect Repellent Lotion with 20% Picaridin, 4 oz
| Active ingredient | 20% Picaridin |
|---|---|
| Form | Lotion |
| Protection time (mosquitoes/ticks) | Up to 14 hours |
| Protection time (biting flies/gnats) | Up to 8 hours |
Sawyer Premium Insect Repellent lotion uses 20% picaridin to provide long-lasting protection for outdoor use where biting insects are a concern. Applied like a regular body lotion, it spreads easily, dries without a greasy film, and has very little lingering odor, which makes it comfortable for all-day wear during hikes, yard work, or time at the water. The manufacturer states up to 14 hours of protection against mosquitoes and ticks and up to 8 hours against biting flies and gnats, so a single morning application often covers an entire outdoor outing. It is safe for use on clothing and gear and will not damage plastics or synthetic coatings, simplifying multi-surface protection. Limitations are that it is a topical repellent only so clothing treatments require a separate permethrin product for extended fabric protection, and effectiveness can vary with heavy sweating or repeated water exposure. For pragmatic users who want reliable, low-odor skin protection against deer flies and other biters, this lotion is an easy-to-use option.
Best for: Practical outdoor users who prioritize reliable, low-odor skin protection during multi-hour activities like hiking, fishing, or yard work and prefer a lotion that applies like a moisturizer.
Less Ideal for: People who need insect protection integrated into clothing or gear should opt for a permethrin clothing treatment instead, and those seeking fragrance-based or natural-only repellents may prefer alternatives.
- 20% picaridin formula offers long-lasting protection against mosquitoes and ticks
- Non-greasy, low-odor lotion that dries quickly and is comfortable for day-long wear
- Safe for use on skin and on gear and synthetic coatings without damaging plastics
- Provides up to 8 hours of protection against biting flies and gnats

|---|---|
| Protection duration | Up to 10 hours |
| Form | Pump spray |
| Net volume | 4 oz |
Repel 100 is a small, travel-friendly pump spray formulated with 98.11% DEET for heavy-duty insect protection.

Choosing the Right Deer Fly Repellent: Key Factors to Consider
Protection Duration and Coverage
How long a repellent keeps deer flies from landing and biting is the single most important factor. Duration varies by active ingredient and concentration. Choose a product that matches the length of your typical outdoor session so you are not reapplying constantly.
Coverage relates to whether the product is meant for exposed skin only or can be used on clothing and gear. Clothing treatment extends protection with fewer reapplications, while skin-only formulas require more frequent attention and careful application to exposed areas like necks and hands.
Active Ingredient and Safety Profile
Different repellents use different active ingredients and each has specific safety guidance. Read label directions for use around children, pets, and while pregnant or breastfeeding. Some active ingredients are intended primarily for clothing treatment and are not suitable for direct skin application.
Understanding the safety profile helps you choose a repellent you can use confidently in the garden, especially if you frequently handle produce, sensitive plants, or work around animals.
Application Method and Practical Use
Form factors include sprays, lotions, wipes, and clothing treatments. Sprays are quick for full-body coverage and gear; lotions can be easier to control on specific areas and often reduce inhalation exposure. Wipes are handy for quick touch-ups in the field.
Consider how you usually spend time outdoors. If you sweat heavily or perform physical labor, opt for formats that adhere well and require fewer reapplications. If you prefer treating outer layers, choose a clothing-applied product.
Resistance to Sweat and Weather
Heat and perspiration can wash repellents from the skin or reduce their effectiveness. Look for products with tested performance against sweat or that specify water resistance. For wet or humid conditions, formulations that bond to fabric or that list sweat resistance are more reliable.
Also consider how rain or pond splashes may impact protection. Some treatments are designed to remain effective on fabrics even after light exposure to moisture, which is important for gardeners working in dewy or rainy environments.
Residue, Odor, and Plant Safety
Residue left on hands or tools can transfer to plants, seed trays, or harvested produce. Choose repellents that leave minimal greasy residue if you plan to handle plants soon after applying. Odor matters for comfort and for being discreet around other people or wildlife.
If you plan to apply repellent while gardening, check that the product does not harm foliage or soil life when incidental contact occurs. Many labels include guidance for accidental contact and recommended wait times before harvesting.
Ease of Reapplication and Portability
How quickly you can top up protection in the field affects how practical a repellent is. Pocket-sized sprays or single-use wipes are best for short outings and hikes. Larger spray bottles or clothing treatments are more economical for regular garden work.
Portability also ties into application method. If you need hands-free protection during long tasks, clothing treatments or wearable formats reduce interruptions and make continuous protection more convenient.
Choosing Between Skin and Clothing Treatments
Skin-applied repellents give direct protection to exposed areas and are ideal when you need coverage on face, wrists, and neck. They are useful for short sessions or when you change clothing frequently. Clothing treatments work by creating a barrier on outer layers and often outlast skin applications, making them better for longer chores or multi-hour outdoor recreation.
When selecting between the two, consider whether you can treat multiple garments or prefer a product that lasts through a whole workday. Clothing treatments reduce the chance of transfer to plants and tools, but remember to follow label instructions on how long treated fabrics should set before use.
- Skin repellents: faster to apply, easier to target exposed areas
- Clothing treatments: longer-lasting, reduce need for reapplication
- Combine methods for high-pressure situations where deer flies are abundant
Practical Application Tips for Gardeners
Apply repellent to pulse points and other exposed skin first, then to clothing if using a spray meant for both. Avoid applying to cuts, irritated skin, or directly to the face; instead spray on hands and rub near the face while avoiding eyes and mouth. Reapply after heavy sweating or if you notice increased fly activity.
Use gloves or wash hands before handling plants after applying a repellent intended for skin. For clothing treatments, allow garments to dry fully outdoors before wearing them in the garden to reduce transfer to foliage.
- Treat collars, cuffs, and hat brims to protect common landing zones
- Follow label wait times before allowing children or pets near treated gear
Managing Repellent Around Children and Pets
Kids and pets often move close to the ground and into vegetation, which increases encounters with deer flies. Choose formulations labeled as appropriate for family use and follow dosage and age restrictions carefully. Keep treated clothing and gear away from infants and observe any wash recommendations.
When walking dogs, avoid applying heavy residue products to hands that will handle leashes. Instead treat the animal's gear or use clothing treatments on yourself to minimize transfer risks.
- Check label age limits and application spacing for children
- Avoid applying near pet fur unless product specifically permits animal use
Scent, Comfort, and Working in Close Quarters
Scent can be a nuisance when gardening near other people or outdoor dining areas. Lighter or neutral-smelling formulas reduce friction with neighbors and wildlife that may be sensitive to strong odors. Heavier creams may feel protective but can leave residues that transfer to plant foliage and tools.
If you are tending sensitive plants or working in confined spaces like greenhouses, choose lower-residue options and ventilate the area after application to minimize any impact on plants and air quality.
- Test a small area of fabric or plant contact to check for staining or residue
- Prefer low-odor options for social garden settings
When to Use Extra Layers of Protection
In high-pressure deer fly seasons combine strategies: wear long sleeves and treated clothing, use a skin repellent on exposed areas, and add physical barriers like hats with netting if needed. Layering reduces reliance on a single product and compensates when sweating or rain reduces one method's effectiveness.
Reserve heavier-duty or longer-lasting treatments for multi-hour outings or tasks where constant reapplication is impractical. For quick tasks around the yard, a light skin application often suffices.
- Layer clothing treatments with occasional skin applications for long projects
- Carry a small reapplication option on long walks or extended garden tasks
How We Chose the Best Deer Fly Repellent
We focused on features that directly influence real-world protection and user experience in outdoor settings. Key evaluation criteria included measured bite reduction time, the repellent's persistence with sweat and humidity, and whether the formulation is suitable for exposed skin or for treating clothing and gear. Application convenience was judged by how quickly a product dries, how easy it is to reapply, and whether a spray, lotion, or wearable option fit different activity types. Safety considerations included label guidance for sensitive skin and suitability around children and pets. We also considered finish and residue, since greasy or heavily scented products change what gardeners will tolerate when handling plants. Products were excluded if they lacked clear protection-duration data or had formulations that explicitly restricted common outdoor uses such as treating outer clothing or using during strenuous activity. The factors above determined which repellents made the shortlist and informed the scoring metrics used across entries.
FAQ
How often should I reapply deer fly repellent?
Reapplication frequency depends on the formulation and your activity level. Many skin-applied repellents suggest reapplying every few hours or after heavy sweating. Clothing treatments generally last longer and require fewer touch-ups but follow label guidance for duration.
Can I use deer fly repellent while gardening around plants and produce?
Yes, but choose low-residue formulas and wash hands before handling produce. If possible, apply repellent to outer clothing rather than directly to hands or tools to minimize transfer to plants.
Are there safe options for children and pregnant gardeners?
Some formulations are labeled for use on children or provide specific guidance for pregnant users. Always read label directions and age restrictions carefully and follow recommended application amounts. If in doubt, consult a healthcare professional for personalized advice.
Do sprays work better than lotions for deer flies?
Sprays offer fast, broad coverage and are convenient for clothing and gear, while lotions can be easier to apply precisely to exposed areas. Effectiveness depends more on the active ingredient and concentration than on the form alone.
Will rain or sweat make my repellent ineffective?
Rain and heavy perspiration can reduce effectiveness, especially for skin-applied products. Look for sweat- or water-resistant formulations if you expect wet conditions, and be prepared to reapply after significant moisture exposure.
Final Verdict
Choose a deer fly repellent based on how long you spend outdoors, whether you prefer skin or clothing treatments, and how much sweating or moisture exposure you expect. Prioritize products with clear protection-duration claims and a safety profile that fits family use and plant-handling practices. For extended garden work, combine treated clothing with periodic skin applications to maintain protection while minimizing residue transfer to plants.
