Tick repellent that actually works, and what to skip

Last updated 2026-08-14

What is the best tick repellent?

The best tick repellents on skin contain DEET, picaridin, IR3535, or oil of lemon eucalyptus (OLE), all registered with the EPA for use against ticks. The CDC states plainly that "EPA-registered insect repellents are proven safe and effective, even for pregnant and breastfeeding women, when applied as directed on the product label" ^[1]. That's an important distinction: safe and effective when used per the label, not safe in some absolute sense with no limits. For gear and clothing rather than skin, permethrin is the standout. It's a synthetic version of a compound found in chrysanthemum flowers, and the EPA and CDC both note that clothing treated with permethrin retains repellent and killing activity through multiple wash cycles, commonly cited around 6 washes for factory-treated items, though homeowner spray-on treatments vary ^[2]. Here's the honest tradeoff. DEET and picaridin work on skin and last a few hours depending on concentration. Permethrin doesn't go on skin at all; it goes on boots, pants, socks, and tents, and it keeps working through laundering. Most people who spend real time in tick habitat (tall grass, leaf litter, wooded trails) use both: permethrin on clothes, DEET or picaridin on exposed skin. No repellent, concentration, or brand eliminates tick contact entirely. Ticks quest from grass and brush and can still land on treated skin or fabric; the repellent's job is to make you a less attractive or less survivable landing spot, not to build a forcefield.

How do you get rid of ticks from your yard?

Getting ticks out of a yard starts with making the habitat less hospitable, then layering on treatment if the population is still a problem. Ticks need humidity and shade to survive; they don't do well in short, sunny, dry turf. The CDC and university extension programs recommend a specific set of yard modifications: keep grass mowed short, remove leaf litter and brush, create a 3-foot-wide barrier of wood chips or gravel between lawns and wooded areas to restrict tick migration, and keep playground equipment and patios away from yard edges and in sunny spots ^[3]. That wood-chip or gravel border is one of the more evidence-backed tips out there, because it physically interrupts how nymphal and adult ticks travel from leaf litter into the areas people actually use. Deer are a major tick host, so fencing them out or removing the plants that attract them can measurably reduce tick numbers over a season, though it's slow and imperfect. Discouraging rodents (stacked wood, bird feeder spillage, brush piles) helps too, since white-footed mice are a primary reservoir for the Lyme disease bacterium. For active infestations, licensed pesticide applications targeting the yard perimeter and shaded harborage areas (not the whole lawn) are the standard approach. Products used include synthetic pyrethroids; timing matters because tick activity peaks seasonally and treating right before nymphs emerge does more good than treating after populations have exploded. A barrier service typically focuses on leaf litter zones, stone walls, wood piles, and the yard's shaded edge rather than blanket-spraying open lawn, since that's where ticks actually live. If you want that assessed for your specific property, a free yard assessment will identify the harborage spots worth treating.

What plants repel mosquitoes and does anything similar work for ticks?

Certain plants, including citronella grass, lemon balm, marigolds, catnip, and lavender, contain compounds that have shown repellent activity against mosquitoes in lab studies, but the effect from simply having the plant growing in your yard is weak and short-lived compared to an applied repellent. The oils have to be extracted, concentrated, and reapplied to skin or fabric to do much; a potted lemon balm plant on the patio is not equivalent to lemon balm oil rubbed on your arms. For ticks, there isn't a comparable folk-plant tradition with real backing. Ticks don't fly toward you the way host-seeking mosquitoes do; they quest by climbing onto vegetation and grabbing passersby, so scent-based deterrents that might nudge a mosquito's flight path don't have the same mechanism to work with. The most plant-derived option with actual tick data is oil of lemon eucalyptus (OLE), and even then it's the refined, EPA-registered product (not garden-variety eucalyptus) that's tested and labeled for tick protection ^[1]. If you like the idea of a repellent-plant border, treat it as a nice-to-have alongside real prevention steps, not a substitute. For a broader rundown of which plants have some evidence behind them, see natural mosquito repellent and natural insect repellent for mosquitoes.

How do you get rid of ticks on your body or pet after being outdoors?

Check your whole body within two hours of coming inside, focusing on the scalp, behind ears, armpits, waistband, and behind knees, since the CDC lists these as ticks' favorite hiding spots ^[3]. Shower soon after coming indoors; it may help wash off unattached ticks and gives you a natural moment to do a visual check. If you find an attached tick, use fine-tipped tweezers, grasp it as close to the skin's surface as possible, and pull upward with steady, even pressure. The CDC specifically warns against folk removal methods: "Avoid folklore remedies such as 'painting' the tick with nail polish or petroleum jelly, or using heat to make the tick detach from the skin. Your goal is to remove the tick as quickly as possible, not waiting for it to detach" ^[4]. After removal, clean the bite area and your hands with rubbing alcohol or soap and water. Watch the site for a rash over the following days to weeks; a expanding red rash, sometimes with central clearing, can signal Lyme disease and warrants a call to your doctor, especially in regions where blacklegged ticks are established. Dispose of a live tick by putting it in alcohol, a sealed bag, or flushing it; some people save it in a labeled bag in case testing becomes relevant later. Dogs and cats need their own tick checks too, run your hands over their coat, especially ears, neck, and between toes, since pets can carry ticks into the house even if the pet itself is protected by a preventive. Ask your vet about a tick preventive product for pets specifically, since human repellents like DEET are not labeled or safe for animal use.

How to keep mosquitoes away and ticks away at the same time

Mosquitoes and ticks like different microhabitats, so a single strategy rarely handles both, but a few overlapping moves cover a lot of ground. Eliminating standing water addresses mosquito breeding almost entirely on its own, while short grass and reduced leaf litter address tick habitat; doing both at once tends to be more effective than either alone, because moist, overgrown yards support both pests. Barrier pesticide treatments applied to vegetation, especially on a recurring cycle through the season, knock down populations of both mosquitoes and ticks that are resting in shrubs, tall grass, and shaded edges. These treatments don't eliminate either population; they reduce numbers for a couple of weeks at a time, which is why services typically re-treat on a 10 to 14 day cycle through the season rather than doing a single spray. If you want the specifics on how that cycle and product selection works, see mosquito control. Personal repellent is still the last line of defense for whichever bugs get past the yard-level controls, and it's worth applying both DEET/picaridin on skin and permethrin on clothes if you're gardening, hiking, or doing yard work in brush or tall grass, more than at dusk for mosquitoes.

How to get rid of mosquitoes and mosquitoes in backyard

Standing water is the single biggest lever for backyard mosquito control, because most common backyard species need still water to complete their life cycle, and some species can go from egg to biting adult in about a week under warm conditions ^[5]. Dump or empty anything holding water after rain: saucers under pots, clogged gutters, kids' toys, tarps, old tires, and birdbaths that aren't changed regularly. For water you can't drain (ornamental ponds, rain barrels), the EPA and CDC both point to mosquito dunks or granules containing Bti (Bacillus thuringiensis israelensis), a naturally occurring bacterium that targets mosquito larvae specifically and is considered low-risk to fish, pets, and beneficial insects when used per label directions ^[5]. Beyond water removal, backyard-scale reduction usually needs a barrier treatment on vegetation, since adult mosquitoes rest on the undersides of leaves in shady, humid spots during the day. A licensed applicator (or a careful homeowner with an EPA-registered product) treats shrubs, tall grass edges, and shaded areas, not open lawn, on a repeat schedule because the treatment breaks down and new adults migrate in from neighboring properties. That's the core of a seasonal barrier plan; see mosquito control near me if you're trying to figure out whether DIY or a hired service makes more sense for your situation. Box fans and porch fans genuinely help too, since mosquitoes are weak fliers and struggle against moving air, which is a low-cost fix for patios and decks that doesn't involve any pesticide at all.

How to get rid of mosquitoes in the house

Indoor mosquitoes almost always trace back to either an opening (torn screen, gap under a door) or a small water source inside, like a plant saucer, a forgotten glass, or a clogged floor drain. Find and fix the entry point first; repeated indoor mosquitoes usually mean something is letting them in repeatedly, not a single unlucky bug. Check window and door screens for tears and gaps, and look at door sweeps, since a quarter-inch gap is enough for mosquitoes to get through. Indoor standing water is worth a real hunt: unused vases, pet water bowls left too long, humidifier trays, and even the tray under houseplants can support larvae if the water sits for a week or more. For mosquitoes already inside, a simple approach is a wet-vac or vacuum to physically remove resting adults from curtains, corners, and under furniture, since mosquitoes rest in dark, still areas between blood meals. Indoor foggers and aerosol insecticides labeled for flying insects can help for an active problem, but always follow the label for room size, ventilation, and re-entry time; these products are EPA-registered for indoor use specifically when applied as directed, not a general-purpose spray for any surface. Citronella candles and plug-in devices offer only modest, localized effect indoors and won't solve a real infestation on their own. If mosquitoes keep coming back despite fixed screens and no standing water, the source is probably outside your door, meaning yard-level control matters even for an indoor problem; see mosquito repellent for repellent options to use in the meantime.

When do mosquitoes go away for the season?

Most mosquito species become inactive once temperatures consistently drop below about 50°F, since their metabolism and flight activity slow dramatically in cold weather, though the exact cutoff varies by species ^[6]. In much of the northern and midwestern U.S., that typically means a hard drop-off after the first sustained frost in fall, while the Gulf Coast, Florida, and parts of the Southwest can see mosquito activity nearly year-round because temperatures rarely stay below that threshold for long. Mosquitoes don't actually die off entirely when it gets cold; many species overwinter as eggs (laid in a location that will flood in spring), while some adult females of certain species find sheltered spots like culverts, hollow logs, or crawl spaces and enter a dormant state called diapause, re-emerging when temperatures warm up ^[6]. That's part of why a mild fall doesn't necessarily mean an early end to mosquito season, and why a series of unusually warm days in what's normally the off-season can bring a temporary population spike. Because the actual cutoff temperature and season length depend heavily on your local climate and the specific mosquito species present, your county or state extension service or health department is the most reliable source for typical local season dates, and they often track it year to year with real trap data rather than a generic rule of thumb.

DEET vs. picaridin vs. permethrin: how do tick repellents actually compare?

Repellent	Where it goes	Typical protection time	Notes
DEET (20-30%)	Skin, clothing	Several hours; higher concentration extends duration, not intensity [1]	Most-studied repellent; avoid under clothing, on cuts, or near eyes
Picaridin (20%)	Skin, clothing	Comparable duration to DEET at similar concentrations [1]	Odorless, less likely to damage plastics/synthetics than DEET
IR3535	Skin	Varies by formulation	EPA-registered; found in some sunscreen-repellent combos
Oil of lemon eucalyptus (OLE) / PMD	Skin	Shorter than DEET/picaridin in most testing	Not recommended for children under 3, per CDC guidance [1]
Permethrin	Clothing, boots, tents, gear only	Through several wash cycles for factory-treated gear [2]	Never apply to bare skin; kills ticks on contact with treated fabric	The practical read: concentration changes how long a skin repellent lasts, not how well it works while it's active. A 10% DEET product and a 30% DEET product both repel ticks effectively; the 30% version just needs reapplying less often. The EPA has a repellent search tool that lets you filter by active ingredient, protection time, and pest type if you want to compare specific registered products rather than guessing from a label alone [7]. Permethrin is the odd one out because it's not a personal repellent at all in the traditional sense; it's a contact insecticide for fabric. Ticks that touch permethrin-treated clothing typically become impaired or die rather than just being repelled, which is a meaningfully different (and often more effective) mechanism for tick-heavy environments like tall grass and trailheads.

Are natural or DIY tick repellents worth using instead?

Some natural-derived repellents have real EPA registration and lab-tested effectiveness, notably oil of lemon eucalyptus (OLE, the refined PMD compound) and IR3535, both of which show up on the CDC's list of repellents effective against ticks ^[1]. These aren't home remedies; they're regulated active ingredients that happen to be plant-derived, and they went through EPA's registration process like DEET and picaridin did. What's genuinely not well-supported: home mixtures of essential oils (citronella, cedarwood, rose geranium, tea tree) applied without EPA registration or concentration testing. Some of these compounds show repellent activity in a lab against certain insects at certain concentrations, but there's no reliable field data on how long they last, how well they hold up to sweat and movement, or their actual protection rate against ticks specifically outdoors. If a bottle doesn't have an EPA registration number, there's no guarantee behind its effectiveness claims or its safety data at all. The honest tradeoff: DIY essential-oil blends smell nicer and avoid synthetic chemicals, but you're trading measured, tested protection for an unknown and probably shorter window of effectiveness. For a short walk in short grass, that might be an acceptable risk to some people. For a hike through brush in a Lyme-endemic county, it's not the choice I'd make personally, and it's not what the CDC recommends as a primary strategy ^[1].

When should you treat your yard for ticks and how often?

Tick season timing depends heavily on species and region, but in much of the eastern and midwestern U.S., blacklegged tick (deer tick) nymphs, the life stage most responsible for Lyme disease transmission, are most active from late spring through summer, roughly May through July, while adults are more active in fall and on warmer winter days . That nymphal peak matters because nymphs are tiny (about the size of a poppy seed) and easy to miss during a tick check, which is part of why that window drives the most disease transmission even though adult ticks are more visible. A barrier yard treatment timed just before that spring nymphal emergence tends to have the most impact per application, though a full-season plan with repeat treatments through summer and into fall covers both nymph and adult activity windows rather than betting on one perfectly timed spray. This is the same logic behind a recurring 10 to 14 day treatment cycle used for mosquito barrier programs; ticks don't need re-treatment quite that often since they're less mobile than adult mosquitoes, but the vegetation treatment itself breaks down and needs refreshing through the season regardless of which pest it's targeting. Because tick species, peak months, and disease risk vary a lot by region (the Pacific Northwest deals with different species and timing than the Northeast or upper Midwest), your local health department or state extension office is the most reliable source for when nymphs typically emerge in your specific county, and many track it with real surveillance data rather than a national average.

Frequently asked questions

What is the best tick repellent for skin?

Products containing 20-30% DEET or 20% picaridin are the most consistently effective skin repellents against ticks, according to CDC and EPA guidance. Oil of lemon eucalyptus (OLE/PMD) and IR3535 are also EPA-registered and effective but typically offer shorter protection windows. Always apply per the product label; higher concentrations extend duration, not strength.

Does DEET actually keep ticks away?

Yes. DEET is EPA-registered specifically for tick protection and is the most studied repellent active ingredient in the U.S. The CDC lists it among repellents proven effective against ticks when applied per label directions. It doesn't create a total barrier, ticks can still contact treated skin, but it measurably reduces attachment.

Can I put permethrin on my skin?

No. Permethrin is registered for use on clothing, boots, and gear only, never directly on skin. It works as a contact insecticide that impairs or kills ticks that touch treated fabric, and factory-treated clothing can retain effectiveness through multiple wash cycles. Use DEET, picaridin, or another EPA-registered skin repellent on exposed skin instead.

How do you get rid of ticks in your yard naturally?

Mow grass short, remove leaf litter and brush, and build a 3-foot barrier of wood chips or gravel between lawn and wooded areas, a CDC-recommended step that restricts tick movement. Keep play areas and patios in sun, away from yard edges, and discourage deer and rodents, both major tick hosts.

How often should a yard be treated for ticks?

There's no single national standard, but many services time a first treatment before spring nymphal emergence (often May in the eastern U.S.) and re-treat through the season as vegetation treatments break down. Confirm typical local timing with your county extension office or health department, since species and peak months vary by region.

What plants repel mosquitoes and do they work for ticks too?

Citronella grass, lemon balm, marigolds, and catnip show some repellent compounds against mosquitoes in lab tests, but just growing them provides weak, short-lived protection compared to applied repellent. There's no comparable evidence base for plants repelling ticks, since ticks quest by climbing vegetation rather than flying toward scent cues.

How do I get rid of a tick that's already attached?

Use fine-tipped tweezers, grasp the tick close to the skin, and pull straight up with steady pressure. The CDC specifically warns against nail polish, petroleum jelly, or heat to remove ticks, since the goal is fast removal, not waiting for the tick to detach on its own. Clean the area afterward with alcohol or soap and water.

When do mosquitoes go away for the year?

Most mosquitoes become inactive once temperatures consistently drop below about 50°F, though the exact point varies by species. In colder regions that usually means after the first hard frost; in warm climates like Florida or the Gulf Coast, mosquitoes can stay active nearly year-round. Confirm local season length with your county extension service.

How do you get rid of mosquitoes in the house fast?

Check screens and door sweeps for gaps, remove any indoor standing water (vases, plant saucers, pet bowls), and vacuum resting adults from curtains and dark corners. For active problems, an EPA-registered indoor aerosol labeled for flying insects can help when used exactly per label directions and ventilation instructions.

How do I keep mosquitoes out of my backyard?

Eliminate standing water weekly (planters, gutters, toys, birdbaths), treat water you can't drain with Bti dunks, and consider a recurring barrier spray on shrubs and shaded vegetation where adults rest during the day. Fans on patios also help since mosquitoes fly poorly in moving air.

Is oil of lemon eucalyptus safe for kids?

The CDC advises against oil of lemon eucalyptus (OLE) products for children under age 3. For younger kids, EPA-registered options at appropriate concentrations, or physical prevention like long sleeves and permethrin-treated clothing (kept off bare skin), are the safer route; check the specific product label for age guidance.

Do ultrasonic or plug-in devices repel ticks or mosquitoes?

There's no reliable field evidence that ultrasonic pest-repellent devices work against ticks or mosquitoes; EPA-registered repellents rely on chemical, not sound-based, mechanisms. Plug-in and candle-based products (like citronella) offer only modest, localized reduction and aren't a substitute for EPA-registered skin repellents or yard-level source reduction.

What's the difference between a mosquito barrier spray and a misting system?

A barrier spray is a scheduled treatment, often every 10-14 days, applied to vegetation and resting sites by a technician. A misting system is a fixed installation that releases pesticide automatically on a timer from nozzles around the property. Both knock populations down temporarily rather than eliminating them; a free yard assessment can help determine which fits your property.
