To apply mosquito repellent to clothes, use a product made for fabric, usually 0.5% permethrin. Spray it outdoors on clothing you are not wearing, coat both sides until the fabric is lightly moistened, and let it dry fully before you put it on. Do not put permethrin on your skin. Protect exposed skin separately with a repellent made for skin. 🌿
That is the short version. Below you will find the full step-by-step method, the drying times, the items you should never treat, and how to cover the gaps that clothing leaves open: ankles, wrists, neck and face.
TL;DR
- ✅ Use a permethrin product labeled for clothing and gear (0.5% is the strength the CDC names). Never use livestock or agricultural permethrin.
- ✅ Spray outdoors on clothes that are not being worn, from about 6 to 8 inches away, until the outer fabric is lightly moistened.
- ✅ Let treated items dry at least 2 hours, or up to 4 hours in humid weather, before wearing them.
- ✅ Never treat underwear, hats or inner clothing, and never apply permethrin to skin.
- ✅ Clothing only covers what it covers. Use a skin-safe repellent on your hands, neck, face and ankles.

What “repellent for clothes” actually means
Most sprays you grab for bare skin are not meant for fabric, and the reverse is true too. The product you want for clothing is permethrin, an insecticide and repellent that is bonded to fabric rather than rubbed on the body.
According to the CDC’s travel health guidance, permethrin at 0.5% on clothing repels and kills ticks, chiggers, mosquitoes and other biting arthropods. So the answer to the common question “does it work on ticks?” is yes, and mosquitoes are covered too.
The CDC says 0.5% permethrin can be used on boots, shirts, pants, socks, tents and backpacks, and that you should follow the product label. It also says permethrin products should not be used directly on skin. That one rule shapes everything else in this guide: permethrin goes on fabric, and a different, skin-appropriate product goes on you.
Two ways to get treated clothing
You have two routes:
- Treat it yourself with a spray (or a soak kit) made for clothing and gear.
- Buy factory-treated clothing, where the repellent is applied before sale.
The EPA notes that factory-treated permethrin clothing is a pesticide product that comes with a use label, commonly a hang-tag, and that you should follow its directions and precautions. Keep that tag. It tells you how long the protection is expected to last.
Before you start: gather the right supplies
Plan your treatment day so it takes ten minutes of work and a few hours of waiting.
- A permethrin spray labeled for clothing and gear
- A clean outdoor spot with good airflow: a driveway, patio, or yard
- A clothesline, hanger, or a clean tarp to lay items flat
- Disposable or washable gloves
- A piece of cardboard or a drop cloth to protect the ground
- Your clothes and gear, clean and dry
Pick the right product
Read the label before anything else. Penn State Extension warns that permethrin made for horses or livestock must not be diluted for use on clothing, and that using a pesticide in a way that differs from its label is unlawful. If the bottle does not mention clothing, leave it on the shelf.
How to apply permethrin to clothes, step by step
The directions below follow an EPA-registered product label and Penn State Extension’s guidance. Your own product’s label always wins if it differs.
Step 1: Go outside and lay clothes out
The label we reviewed requires application outdoors, on clothing that is not being worn. Hang items on a line or lay them flat on a tarp. Penn State Extension also recommends good ventilation. Avoid breathing the spray, and never spray in an enclosed space, as the EPA’s safety guidance says.
Step 2: Do a test spot
Shake the container, then make a test application on a hidden area of the fabric, such as an inside seam or hem. Wait for it to dry. If the color or finish changes, skip that item.
Step 3: Spray from the right distance
Hold the container about 6 to 8 inches from the clothing. Spray in even, sweeping passes until the outer fabric is lightly moistened or slightly darkened. You are not trying to soak the item through. A light, even film beats a drenched spot.
Step 4: Treat both sides and the high-risk areas
Penn State Extension advises treating both sides of the fabric. Pay extra attention to the places mosquitoes and ticks reach first:
- Sock cuffs and the tops of boots
- Pant hems and the lower legs
- Shirt cuffs and collars
- The edges of backpack straps and tent mesh
Step 5: Let it dry completely
The EPA label requires treated items to dry at least 2 hours before wearing or use, or 4 hours in humid conditions. Penn State Extension gives the same window. If you are packing for a trip, treat items the day before.
Step 6: Store and wash with care
Once dry, the clothes are ready to wear. Keep the leftover product out of children’s reach, such as in a locked cabinet or garden shed, as the EPA recommends.
What you should never treat
The same EPA-registered label prohibits treating underwear, hats, caps and inner clothing. Think of it this way: permethrin is for outer layers that sit away from the most sensitive areas of the body. Even though the CDC’s Yellow Book mentions hats among items travelers can treat, follow your own product’s label. If the label says no, the answer is no.
More rules that keep treatment safe:
- Do not use permethrin on skin. The CDC is clear on this.
- Do not spray into the face or near your breathing zone.
- Do not treat clothing while it is on you or your child.
- If you have cats, spray well away from them. Penn State Extension says permethrin is extremely toxic to cats before it dries, though dried clothing is safe to wear around them.
How long does treated clothing keep working?
The honest answer: it depends on the product. The CDC says factory-treated items can stay protective through multiple washings, but you should read the label to see how long protection lasts. The CDC’s travel guidance adds that treated materials hold repellency after repeated laundering, but should be retreated as the label describes.
A practical routine for outdoor families:
- Write the treatment date inside the garment with a laundry marker.
- Check the label for the retreatment interval.
- Retreat at the stated interval, or sooner if you notice more bites on treated items.
- Keep a small “bug kit” of treated hiking socks, pants and a long-sleeve shirt, so you grab protection fast.
Clothing is half the plan
Here is what experienced campers learn quickly: treated clothing protects the parts of you that fabric covers. Mosquitoes still go for the bare patches. That includes your face, neck, hands, wrists and the strip of ankle between sock and pant.
Some readers also report getting bitten through clothing. A tight, thin fabric can let a mosquito’s mouthparts reach the skin. Loose, thicker weaves help. Our guide on loose jeans, layering and permethrin explains when each option makes sense. And if you are dressing kids, see how light clothing reduces mosquito bites for kids and which colors repel mosquitoes and which don’t.
A simple layered system
| Zone | What to use | Why |
|---|---|---|
| Shirt, pants, socks, boots | Permethrin made for clothing, applied as directed | Treats the fabric, not the skin |
| Face, neck, hands, wrists, ankles | A skin-safe repellent | These spots are never covered by treated cloth |
| Camp, tent, backpack | Permethrin for gear (per label) | Keeps resting spots less inviting |
| Backyard | Habits that reduce standing water | Fewer mosquitoes to begin with |
The EPA says repellents should go only on exposed skin and/or clothing, never underneath clothing. After you come indoors, wash treated skin and clothes with soap and water, as the agency advises.
Protecting the skin that clothing leaves out
This is where we come in. Our Mosquito Bee Gone™ line is made for skin: DEET-free, all-natural balms, roll-ons and ointments. A roll-on is handy for precise application along the neck, wrists and ankles without spraying near your face. A balm is easy to pat onto a child’s hands and ears (apply it to your own hands first, then to your child).
If you want a deeper look at timing, read our guide on how long mosquito repellent lasts and when to reapply. For big outdoor days, our natural mosquito balm overview walks through application.
Situations that call for the full system
Hiking in humid woods. Sweat, damp air and long hours mean you need both treated clothes and fresh skin protection. See our hiking mosquito protection guide for high humidity.
Dusk on the patio. Mosquito activity often rises around dusk, and a quick roll-on on ankles helps when shorts are the dress code. Our dusk activity guide has more.
Camping with kids. Treat the pants and socks yourself, in advance and away from the children. Then use a skin balm at the campsite. Keep treatment products locked away.
Surf sessions and beach evenings. Wetsuits and swimwear are not usually the right place for permethrin. Check the label first, and put protection on skin and on a cover-up layer that you treat separately.
A weekend prep checklist
- ☐ Wash and dry the clothes you plan to treat.
- ☐ Read the permethrin label from top to bottom.
- ☐ Set up outdoors, wear gloves, and lay items flat.
- ☐ Test a hidden spot.
- ☐ Spray from 6 to 8 inches, both sides, until lightly moistened.
- ☐ Let everything dry for at least 2 hours (4 in humid weather).
- ☐ Pack a skin repellent for face, neck, hands and ankles.
- ☐ Store leftover product out of children’s reach.
For a skin-first routine that works year round, our skin care mosquito prevention checklist pairs well with this one. And at home, small yard habits and a plan for backyard sunsets cut down the number of bugs you have to deal with.
Our perspective
We hear the same story from families, campers and surfers: they do everything right with their clothes, then end up with bites on the one patch they forgot. That is why we think of protection as a system, not a single product.
Treated clothing handles the fabric. For skin, we built Mosquito Bee Gone™ to be DEET-free, all natural, bee-friendly and gentle enough for families to use. Our products are tested by real families, and we keep improving them based on what customers tell us.
Our advice is simple: treat your outer layers as the label directs, then add a skin-friendly balm or roll-on to the exposed spots. If a bite does sneak through, our Bug Bite Relief line is there to help you feel more comfortable afterward.

FAQ
Can I spray mosquito repellent on my clothes while I’m wearing them?
Skin repellents may go on exposed skin and clothing, according to the EPA, but never under clothing. Permethrin is different: the label we reviewed requires treating clothes that are not being worn. Take the items off, spray them outdoors, and let them dry before putting them on.
How long does permethrin take to dry on clothes?
The EPA label we cited requires at least 2 hours of drying before you wear or use treated items, or 4 hours in humid conditions. Penn State Extension gives the same guidance. Give humid days the longer window.
Does permethrin-treated clothing work on ticks too?
Yes. The CDC says clothing treated with 0.5% permethrin repels and kills ticks, chiggers and mosquitoes, along with other biting arthropods. Still check yourself for ticks after outdoor time, as Penn State Extension suggests.
Can I use the permethrin from my horse or farm supplies?
No. Penn State Extension says permethrin made for horses or livestock must not be diluted for clothing, and using a pesticide against its label is unlawful. Buy a product labeled for clothing and gear.
Is it safe to put permethrin on kids’ clothes?
You can follow the product label for the items it allows, but treat them yourself, outdoors, while children are away. Let the clothing dry fully before dressing a child. Keep the product locked up, and ask your pediatrician if you have questions about your child. Never apply permethrin to skin.
