DEET vs Picaridin vs Yard Repellent Treatments for Family Safety
Heading outside in mosquito season, families face a real choice. Spray DEET on the kids, switch the whole household to picaridin, treat clothing with permethrin, hire a pro for a yard barrier treatment, or stack a few together?
Each option has a different safety profile, a different age cutoff, and a different role in a real routine. The wrong choice either leaves a child unprotected from a vector-borne illness or puts a product where it was never meant to go.
This guide compares the four most common mosquito protection options against EPA and CDC guidance, with notes on infants, pregnancy, application zones, and what to do when everyone walks back inside.
Mosquito protection is one of the few household decisions where EPA and CDC publish unusually clear guidance, yet most families still grab whatever's on the store shelf. The differences between active ingredients aren't marketing fluff. DEET and picaridin behave differently on plastics and synthetic fabrics. Permethrin's engineered to bond to clothing and isn't meant for skin. A professional yard barrier treatment is a property-wide tool, not a personal one.
This guide gives parents enough to mix and match the right options for their household. By the end you'll know which product belongs on a toddler, which belongs on a stroller cover, which belongs on hiking pants, and which belongs on the perimeter of the backyard.
Key Takeaways
- EPA-registered repellents with DEET (10-30% for kids), picaridin (20%), IR3535, or oil of lemon eucalyptus are all safe and effective when used per the label.
- CDC and EPA agree: don't use DEET or picaridin on infants under 2 months. Don't use oil of lemon eucalyptus on children under 3 years.
- CDC states pregnant and breastfeeding adults can use EPA-registered repellents, including DEET and picaridin, at appropriate concentrations per label.
- Permethrin's for clothing, gear, and tents only. Never on skin. Treated items hold up through several wash cycles.
- Professional yard barrier treatments reduce property-level mosquito pressure but don't replace personal repellent during peak biting hours or in heavily wooded areas.
The Family Protection Question
First warm evening of the season. The kids want to eat dinner outside, the dog needs a walk, and the mosquitoes have already found the back deck. A parent stands in front of the bathroom cabinet looking at a 3-year-old spray bottle of DEET, a newer picaridin pump, permethrin-treated camp pants from a recent trip, and a flyer from a company that treats the yard once a month. Which one's right for a 6-month-old, a 4-year-old, and two adults, one of whom is pregnant?
No single product solves the problem for the whole family. EPA-registered repellents have different age cutoffs, different application zones, and different interactions with plastics, synthetic fabrics, and sunscreen. Yard barrier treatments work at a different scale entirely. A safe family routine is usually a small stack: the right repellent on skin for each age group, treated clothing for higher-risk activities, and a property-level treatment when pressure is genuinely heavy.

Specific Safety Pointers for Each Option
Each option has a short list of practical rules pulled from EPA and CDC guidance and from how families actually use these products.
DEET (10-30% for Family Use)
DEET's EPA-approved for kids 2 months and older at concentrations of 10-30%. Apply once per outing, not repeatedly, and avoid spraying on the hands or face of small children (spray your own hands and pat it on instead). Skip cuts, irritated skin, and the area around the eyes and mouth. DEET can damage some plastics and synthetic fabrics, so keep it off watch crystals, sunglasses lenses, stroller canopies, and rain jackets. Wash it off with soap and water as soon as everyone's back inside, and run treated clothing through a regular wash before re-wearing.
For most family yard time, 20% DEET's plenty. Higher concentrations only extend duration, not the quality of protection.
Picaridin (20% for Family Use)
Picaridin at 20% delivers protection comparable to a similar concentration of DEET and is gentler on plastics, watch faces, sunglasses, and most synthetic gear. Same age guidance: not for infants under 2 months, and avoid hands and face on small children. Picaridin feels less greasy and has very little odor, which makes it easier to use daily with kids who don't want to be sprayed at all. Wash off with soap and water at the end of the day, and reapply per the label, not on a guess.
Picaridin's often the right default for families with young kids, electronics, and synthetic outdoor gear. It lasts long enough at 20% and doesn't damage the plastic on a stroller or backpack.
Permethrin-Treated Clothing (Never on Skin)
Permethrin's a different category. It goes on clothing, hats, shoes, gear, and tents, and it's never applied to skin. Once dry, it bonds to the fabric and continues to repel and kill mosquitoes and ticks through several wash cycles, depending on the product. Treat clothing in a well-ventilated area, away from cats (wet permethrin's toxic to cats; dried treated fabric's fine), and let everything fully dry before wearing. Pre-treated factory clothing is also widely available for families that'd rather not apply it themselves.
Permethrin clothing pairs well with picaridin or DEET on exposed skin. The clothing handles the covered areas while a skin repellent handles arms, neck, and ankles.
Yard Barrier Treatment (Property-Level Tool)
A professional yard barrier treatment targets resting mosquitoes in shaded vegetation, dense shrubs, and around fence lines. A typical visit cuts pressure on the property for several weeks, but it's not a substitute for repellent during peak biting hours or in wooded areas off-property. Ask the provider what active ingredient they apply, what the re-entry interval (REI) is for kids and pets, and how long after treatment everyone should stay off the wet grass. Most products dry within 30 minutes to a few hours, after which families can return to normal use.
Schedule treatments early in the day so the product dries before evening outdoor time. Confirm the REI in writing for any household with infants, pregnant adults, or pets.
Infant Guidance (Under 2 Months)
EPA and CDC are explicit: don't use DEET or picaridin on infants under 2 months. For this age group, the approach is physical exclusion. Use mosquito netting on strollers, carriers, and cribs, dress the infant in lightweight long sleeves and pants, and keep them out of heavy mosquito areas at dawn and dusk. Permethrin-treated stroller covers and netting are an option for the gear, since the active ingredient stays on the fabric and away from the baby's skin.
A fitted mosquito net over the stroller or play yard is the most reliable protection for an infant, even on a treated property.
Pregnancy and Breastfeeding
CDC states that pregnant and breastfeeding adults can use EPA-registered insect repellents, including DEET and picaridin, at appropriate concentrations per the product label. Mosquito-borne illnesses like Zika and West Nile virus pose a meaningful pregnancy risk, and bite protection is part of routine prenatal guidance. Apply the repellent to your own hands first and pat it on, avoid the face and any irritated skin, and wash it off when you come inside. The risk of skipping repellent in a high-mosquito area is generally higher than the risk of using one as directed.
If you'd prefer a non-DEET option during pregnancy, picaridin at 20% is widely used and follows the same EPA-registered label guidance.
After Coming Inside
Wash repellent off with soap and water as soon as everyone's back indoors for the day. Run treated clothing through a regular wash before re-wearing if it was sprayed with DEET or picaridin (permethrin-treated clothing follows its own product instructions, usually multiple washes per treatment). Store products out of reach of children and away from heat. Avoid combination sunscreen-plus-repellent products in most cases. Sunscreen needs reapplying more often than repellent does, and re-spraying repellent every 90 minutes is more than the label calls for.
Apply sunscreen first, let it absorb, then apply repellent on top. This sequence matches CDC guidance and avoids over-applying the repellent.
Stacking Options for a Real Family Routine
The biggest mistake families make is treating these options as competitors. They're not. Picaridin on the toddler's arms, permethrin on the parent's hiking pants, mosquito netting on the infant's stroller, and a yard barrier treatment around the perimeter all do different jobs at different scales. The right routine is usually a stack of two or three of these, chosen for the activity and the ages involved.
A useful planning move is to separate decisions by zone. The yard is one zone, handled by a property-level treatment if pressure justifies it. Clothing and gear is another zone, handled by permethrin or pre-treated fabrics for older family members. Exposed skin is the third zone, where DEET or picaridin do most of the work for everyone over 2 months old. When a family thinks in zones rather than products, the choices stop competing and start covering each other.
Two Mistakes Families Make With Mosquito Protection
Spraying Permethrin on Skin
Permethrin's engineered for fabric, not skin. The label is explicit, but every season some families spray it directly on arms or legs because the bottle looks similar to a regular repellent. Apply permethrin to clothing only, in a ventilated area, and let it fully dry before wearing. For exposed skin, switch to a DEET or picaridin product appropriate for the ages involved.
Skipping Repellent During Pregnancy
Some pregnant adults skip repellent entirely out of caution and end up exposed to mosquito-borne illnesses that pose a much greater risk than the repellent itself. CDC guidance is clear that EPA-registered repellents at appropriate concentrations are safe during pregnancy. Picaridin at 20% is a common pick for pregnant adults who want a non-DEET option, and the same application rules apply: avoid the face, wash it off when coming inside, and follow the product label.
Mosquito Protection Options Compared
Four options, each with a different role in a family routine. Concentrations and age cutoffs reflect EPA and CDC guidance.
| DEET (10-30% on skin) | Picaridin (20% on skin) | Permethrin (clothing only) | Yard Barrier Treatment | |
|---|---|---|---|---|
| Where it goes | Exposed skin and over clothing | Exposed skin and over clothing | Clothing, gear, tents (never on skin) | Yard perimeter, shrubs, shaded resting spots |
| Minimum age (per EPA/CDC) | 2 months and older | 2 months and older | Any age (treated clothing only) | Property-level, not age-specific |
| Pregnancy guidance | CDC: safe at appropriate concentrations per label | CDC: safe at appropriate concentrations per label | Safe on treated clothing only | Stay off the lawn until treatment's fully dry |
| Effect on plastics and synthetics | Can damage plastics, watch faces, some synthetic fabrics | Gentler on plastics and gear | Bonds to fabric, low impact on plastics | Not applied to personal items |
| Typical hours of protection | About 2-6 hours at 10-30% | About 8-14 hours at 20% | Multiple wash cycles per treatment | Several weeks per professional visit |
| Best role in family routine | Short outdoor windows in heavy mosquito areas | Daily wear-and-tear, gear-friendly families | Hiking, camping, yard-work clothing | Backyard reduction during outdoor entertaining season |
Concentrations and durations are general references based on EPA-registered product labels and CDC guidance. Always follow the specific product label for the item you have on hand.
What EPA and CDC Say About Family Repellent Use
EPA and CDC guidance: don't apply DEET or picaridin to infants under 2 months. For this age group, use mosquito netting and protective clothing instead of chemical repellents.
CDC states pregnant and breastfeeding adults can use EPA-registered insect repellents, including products containing DEET and picaridin, at appropriate concentrations per the product label.
EPA registers permethrin for use on clothing, gear, and tents, not on skin. Once dry, treated fabric continues to repel mosquitoes and ticks through several wash cycles, depending on the specific product.

Three Factors That Decide Your Mix
Three variables drive the right combination of repellent, treated clothing, and yard treatment for any household. Match each to your situation before picking products.
-
Ages in the Household
Infants under 2 months rely on netting and clothing, not chemical repellents. Kids 2 months and older can use DEET or picaridin at family-appropriate concentrations. Oil of lemon eucalyptus waits until age 3. The youngest age in the house often sets the strictest rule.
The Bottom Line
Family mosquito protection is a layered question, not a single-product question. Picaridin and DEET both work on skin for everyone over 2 months old, with picaridin generally easier on plastics and synthetic gear. Permethrin handles clothing and tents and never goes on skin. A professional yard barrier treatment knocks down property-level pressure during heavy mosquito season, but doesn't replace personal repellent.
The simplest version of a safe family routine: protect infants under 2 months with netting and clothing, use 20% picaridin or an appropriate DEET concentration on older kids and adults, treat hiking and yard-work clothing with permethrin, and book a yard treatment if your property genuinely has heavy pressure. Read the label on each product, follow the application rules, and call a professional when property-level pressure is more than personal protection alone can manage.
Mosquito Protection Safety FAQs
Common questions about DEET, picaridin, permethrin, and yard barrier treatments for families.
-
Is it safe to use DEET on my toddler, or should I switch to picaridin? Toggle answer for: Is it safe to use DEET on my toddler, or should I switch to picaridin?
EPA and CDC both list DEET as safe for children 2 months and older at concentrations of 10 to 30 percent when used per label. Apply once per outing, not repeatedly, skip the hands and face on small kids (spray your hands first and pat it on), and avoid cuts or irritated skin. For most family yard time, 20 percent DEET is plenty.
Picaridin at 20 percent gives comparable protection, is gentler on plastics and synthetic gear, feels less greasy, and has very little odor. It follows the same age guidance: not for infants under 2 months. Many parents default to picaridin for daily use because kids tolerate it better and it does not damage stroller plastic or sunglasses lenses.
-
How do I protect a baby under 2 months old from mosquitoes if I can't use repellent? Toggle answer for: How do I protect a baby under 2 months old from mosquitoes if I can't use repellent?
EPA and CDC are explicit: DEET and picaridin should not be applied to infants younger than 2 months. The recommended approach for that age group is physical exclusion. Use a fitted mosquito net over the stroller, carrier, crib, or play yard, dress the baby in lightweight long sleeves and pants, and avoid heavy mosquito areas at dawn and dusk.
Permethrin-treated stroller covers and netting are an option for the gear itself, since the active ingredient stays bonded to the fabric and never contacts the baby's skin. A net plus permethrin-treated covers is the most reliable layered protection for an infant, even on a property that has been professionally treated.
-
Can I spray permethrin on my arms and legs like regular bug spray? Toggle answer for: Can I spray permethrin on my arms and legs like regular bug spray?
No. Permethrin is registered for clothing, gear, and tents only and is never applied to skin. Once it dries on fabric it bonds in place and continues to repel and kill mosquitoes and ticks through several wash cycles, depending on the product. The bottles can look similar to skin repellents, so check the label before spraying.
Apply permethrin in a ventilated area, away from cats while wet (dry treated fabric is fine for cats once it has cured), and let everything dry fully before wearing. For exposed skin, switch to DEET or picaridin in age-appropriate concentrations.
-
Is picaridin safe to use during pregnancy? Toggle answer for: Is picaridin safe to use during pregnancy?
CDC states that pregnant and breastfeeding people can use EPA-registered insect repellents, including picaridin and DEET, at appropriate concentrations and per the product label. Mosquito-borne illnesses such as Zika and West Nile virus pose a meaningful pregnancy risk, and bite protection is part of routine prenatal guidance.
Picaridin at 20 percent is a common pick for pregnant adults who want a non-DEET option. The application rules are the same: avoid the face, do not spray on irritated skin, apply to your own hands first and pat it on, and wash it off when you come back inside.
-
Does a professional yard treatment replace bug spray for the family? Toggle answer for: Does a professional yard treatment replace bug spray for the family?
No. A yard barrier treatment targets resting mosquitoes in shaded vegetation, dense shrubs, and along fence lines, and it can knock down property-level pressure for several weeks per visit. It does not replace personal repellent during peak biting hours, in heavily wooded areas, or once anyone leaves the property.
Think of it as one layer of a stack: yard treatment for the property, picaridin or DEET on exposed skin, permethrin-treated clothing for hikes and yard work, and netting for any infant under 2 months. Each tool covers what the others cannot.
-
How long after a yard mosquito treatment can my kids and pets go back outside? Toggle answer for: How long after a yard mosquito treatment can my kids and pets go back outside?
Most professional yard barrier products are dry within 30 minutes to a few hours, and once dry the treated areas are typically fine for normal use. Ask your provider in writing for the specific re-entry interval (REI) for the product they applied, and confirm any extra precautions for households with infants, pregnant adults, or pets.
A practical move is to schedule treatments early in the day so the product can fully cure before evening outdoor time. Avoid letting kids or pets onto wet grass right after application, and follow whatever the technician puts on the door tag.
-
Should I use a combo sunscreen-and-bug-spray product on my kids? Toggle answer for: Should I use a combo sunscreen-and-bug-spray product on my kids?
CDC guidance discourages combination products in most cases. Sunscreen needs to be reapplied every 90 minutes to two hours, while DEET and picaridin do not. Re-spraying a combo product on the sunscreen schedule means over-applying the repellent, which the label does not call for.
The recommended sequence is sunscreen first, let it absorb for 15 minutes, then apply the repellent on top. Reapply sunscreen as needed without reapplying the repellent unless the label calls for it.
