Ticks are tiny arachnids that can attach to people and animals during hikes through grassy, brushy, or wooded areas. Some ticks carry bacteria, viruses, or parasites that can cause illnesses such as Lyme disease, Rocky Mountain spotted fever (RMSF), anaplasmosis, babesiosis, ehrlichiosis, and other tick-associated conditions. The good news is that a layered prevention routine before, during, and after your hike can greatly reduce your chances of being bitten.
Quick Answer
To avoid ticks while hiking, wear long clothing, use an EPA-registered repellent labeled for ticks, consider 0.5% permethrin-treated clothing and gear, stay in the center of trails, avoid brushing against tall grass and shrubs, and perform a full-body tick check as soon as you return home.
Key Takeaways
- Ticks usually climb onto hikers from grass, shrubs, leaf litter, animals, and other low vegetation; they do not fly or jump.
- Wear long sleeves, long pants, closed-toe footwear, and light-colored clothing so crawling ticks are easier to see.
- Use an EPA-registered skin repellent labeled for ticks and follow the product label carefully.
- Treat boots, clothing, and gear with a product containing 0.5% permethrin when appropriate, but never apply permethrin directly to your skin.
- After hiking, check your body, clothing, gear, children, and pets; shower soon after coming indoors and remove attached ticks promptly.
At a Glance
| Time Required | About 5–10 minutes of preparation before hiking, plus a careful post-hike tick check |
| Difficulty | Easy |
| Tools Needed | EPA-registered tick repellent, protective clothing, fine-tipped tweezers, dryer; optional 0.5% permethrin treatment |
| Cost | Low; varies by repellent, clothing, and whether you use pre-treated gear |
Warning: Tick-borne diseases cannot be diagnosed from an article or from the appearance of a tick alone. If you develop fever, an expanding rash, severe headache, unusual fatigue, muscle aches, neurologic symptoms, or other illness after a tick bite or likely tick exposure, contact a healthcare professional promptly.
Understand Where Ticks Are Most Likely to Be
Ticks live in grassy, brushy, wooded, and leaf-littered environments, and they can also be carried by animals. According to the Centers for Disease Control and Prevention (CDC), people can encounter ticks while hiking, camping, gardening, hunting, walking a dog, or simply spending time in their own yard.
Ticks do not fly or jump. Many species use a behavior called questing: they wait on grass, leaves, or shrubs with their front legs extended and climb onto a person or animal that brushes past. That is why contact with trail-edge vegetation, tall grass, brush, and leaf litter deserves more attention than overhead branches.
Tick exposure can happen throughout the year. Activity is generally highest during warmer months, and the CDC notes that ticks are especially active from roughly April through September. Some adult blacklegged ticks, however, may search for hosts whenever winter temperatures rise above freezing.
Risk also varies by region and tick species. Blacklegged ticks are widespread across much of the eastern United States, while western blacklegged ticks occur primarily along the Pacific Coast. Lone star ticks are widely distributed across the Northeast, South, and Midwest. Use the CDC’s regional information rather than assuming every tick species or disease is equally common everywhere.
Note: A county without a documented established tick population is not automatically tick-free. Local surveillance varies, so your state or local health department can provide more specific risk information.
Choosing the Right Clothing for Tick Prevention
When hiking in tick habitat, clothing provides a useful physical barrier. Wear long-sleeved shirts, long pants, and closed-toe shoes or boots when conditions allow. Tightly woven fabric can make it harder for ticks to reach your skin.
Light-colored clothing is useful because dark ticks are easier to spot while they are still crawling. Consider tucking your shirt into your pants and your pant legs into your socks or boots when you will be moving through especially brushy or grassy terrain.
Gaiters can add another barrier around the ankle and lower leg. A hat can also cover the scalp and make post-hike inspection easier, especially if you have long or thick hair. However, the main reason to cover your head is not because ticks commonly fall from tree branches; ticks usually get onto hikers after contact with vegetation or animals.
Pro Tip: Before leaving the trailhead, place a pair of fine-tipped tweezers in your first-aid kit. Prompt removal is safer than waiting until you can buy a removal tool later.
Using Insect Repellent Effectively
Use an EPA-registered skin-applied insect repellent that is labeled for ticks. Registered active ingredients include DEET, picaridin, IR3535, oil of lemon eucalyptus, PMD, and 2-undecanone, among others. Protection time varies by product and concentration, so read the label rather than assuming every repellent lasts the same amount of time.
Apply enough product to cover exposed skin and any clothing surfaces allowed by the label. Do not apply repellent underneath clothing unless the product label specifically directs you to do so. Avoid cuts, wounds, irritated skin, eyes, and the mouth.
When applying a spray to your face, spray it onto your hands first and then spread it carefully over exposed facial skin. Do not spray directly into the face. When using repellent on children, adults should apply it to their own hands first and then put it on the child as directed by the label. Do not allow young children to handle or apply the product themselves.
Some oil of lemon eucalyptus and PMD products carry age restrictions for children, so always check the exact label. EPA guidance also recommends washing treated skin after returning indoors.
Staying on Marked Trails and Avoiding Tall Grass
| Trail Situation | Exposure Concern | Safer Choice |
|---|---|---|
| Center of a clear trail | Less contact with vegetation | Stay centered whenever practical |
| Brushy trail edge | Ticks may be waiting on leaves or stems | Avoid brushing legs and arms against vegetation |
| Tall grass or leaf litter | Greater opportunity for tick contact | Reroute when possible or use full protective measures |
| Hiking with a dog | Pets can pick up ticks and carry them home | Keep the dog controlled and check it carefully afterward |
Staying in the center of a maintained trail is one of the simplest ways to reduce contact with tick habitat. Avoid brushing your legs, arms, pack, or clothing against tall grass, shrubs, and dense undergrowth whenever you can.
If a trail becomes overgrown and you have no practical alternate route, make sure your protective clothing is secured, your repellent is still within its labeled protection period, and you inspect yourself once you are back in a clear area.
When hiking with pets, keep them under control rather than allowing them to roam through dense brush. Pets can become ill from tick-borne diseases and can also carry ticks back into a vehicle or home.
Checking for Ticks After Hiking
Perform a full-body tick check as soon as practical after leaving a tick-prone area. A mirror can help you inspect places that are difficult to see.
The CDC recommends paying particular attention to:
- Under the arms
- In and around the ears
- In and around the hair and scalp
- Inside the belly button
- Around the waist
- Between the legs and around the groin
- Behind the knees
- Around sock lines, ankles, and other clothing edges
Check children carefully as well. Ticks can be extremely small, especially during the nymph stage, so look and feel for tiny bumps rather than searching only for large adult ticks.
Inspect clothing, hats, backpacks, coats, trekking gear, and other items that brushed against vegetation. A crawling tick on gear can attach later even if it never reached your skin during the hike.
How to Remove an Attached Tick Safely
If you find an attached tick, remove it promptly. The CDC advises that you do not need to wait for a healthcare provider simply to remove an ordinary attached tick.
- Use clean fine-tipped tweezers. Grasp the tick as close to the skin’s surface as possible. If fine-tipped tweezers are unavailable, regular tweezers can also be used.
- Pull upward with steady, even pressure. Do not twist or jerk the tick.
- Do not squeeze the tick’s body. Grip close to the skin instead.
- If mouthparts remain, remove them with tweezers if they come out easily. If they cannot be removed easily, leave them alone and allow the skin to heal.
- Dispose of the tick safely. Place it in a sealed container, wrap it tightly in tape, put it in alcohol, or flush it down the toilet. Do not crush it with bare fingers.
- Clean the area. Wash the bite and your hands with soap and water, rubbing alcohol, or hand sanitizer.
- Check the rest of your body. Finding one tick means another may also be present.
Warning: Do not cover an attached tick with petroleum jelly or nail polish and do not apply heat in an attempt to make it detach. Current CDC guidance advises against these methods because they can agitate the tick. Use mechanical removal instead.
Showering and Washing Clothes After Hiking
Shower Within Two Hours
Shower as soon as practical after coming indoors. CDC guidance notes that showering within two hours has been associated with a lower risk of tick-borne disease and gives you another opportunity to find ticks that are crawling on your skin but have not attached.
Use the shower as a second full-body inspection rather than assuming water alone will remove every tick.
Wash and Dry Clothes
Handle hiking clothing promptly. If your clothes are already dry, the CDC recommends tumble-drying them on high heat for 10 minutes to kill ticks. Damp clothing may require additional drying time.
If the clothing needs to be washed first, use hot water when the fabric allows it. CDC guidance notes that cold and medium-temperature water may not kill ticks. After washing, dry the clothing thoroughly according to the garment-care instructions.
Reduce the Risk of Tick Bites
Inspect backpacks, jackets, hats, footwear, trekking poles, camping equipment, and other gear before storing them. Ticks can ride into a home on clothing, equipment, or pets and attach to someone later.
Check dogs and other outdoor pets carefully after a hike. The CDC recommends daily tick checks for pets that spend time outdoors. Talk with your veterinarian about an appropriate preventive product for your animal.
Warning: Never assume a flea-and-tick treatment that is safe for a dog is also safe for a cat. Cats can be extremely sensitive to certain chemicals, so ask a veterinarian before applying a tick-control product to a cat.
Treating Gear with Permethrin
Permethrin is used on clothing and gear rather than directly on exposed skin. The CDC recommends products containing 0.5% permethrin for treating items such as boots, pants, shirts, socks, and camping gear when used according to the product label.
You can buy factory-treated clothing or use a consumer permethrin product that is specifically labeled for treating fabrics. Follow the manufacturer’s directions for application, drying time, retreatment, washing, storage, and disposal.
Permethrin-treated items can continue providing protection through multiple washings, but the exact duration depends on the product. Check the label rather than assuming treatment remains effective for a fixed number of weeks or months.
Warning: Do not apply clothing-treatment permethrin directly to your skin. Use it only on items allowed by the product label and let treated gear dry completely before use when the label instructs you to do so.
Being Aware of Tick-Borne Diseases and Seeking Medical Attention
Different tick species transmit different pathogens, so a tick bite does not automatically mean you will develop Lyme disease or any other illness. Still, knowing what to watch for can help you seek care promptly.
Lyme disease in the United States is mainly spread by infected blacklegged ticks. In most cases, an infected blacklegged tick must remain attached for more than 24 hours before transmitting Lyme disease bacteria, which is one reason prompt removal matters. That timing does not apply equally to every tick-borne disease, so never use the “24-hour rule” as a reason to ignore symptoms after another type of tick exposure.
CDC estimates that roughly 476,000 people are diagnosed and treated for Lyme disease in the United States each year, underscoring why bite prevention remains important for hikers.
Early Lyme disease may cause fever, chills, fatigue, headache, muscle or joint aches, swollen lymph nodes, and an expanding rash called erythema migrans. The rash can have many appearances. Some develop central clearing and resemble a target or “bull’s-eye,” but many do not.
RMSF can cause fever, severe headache, nausea, muscle pain, abdominal symptoms, and rash. Importantly, the rash may not appear during the first few days. The CDC warns that RMSF can progress rapidly, so people should not wait for a rash before seeking care when compatible illness follows likely tick exposure.
Ticks are also associated with anaplasmosis, babesiosis, ehrlichiosis, tularemia, Powassan virus disease, and other illnesses. Certain tick bites can also contribute to alpha-gal syndrome, a potentially serious allergy to alpha-gal found in mammalian meat and some other products.
What to Do After a Known Tick Bite
After removing the tick, note when the bite occurred and where you probably picked up the tick. A clear photograph can be useful for identification discussions, although identification alone cannot tell you whether you became infected.
Monitor your health over the following days and weeks. If you develop fever, an expanding rash, severe headache, unusual fatigue, muscle or joint pain, facial weakness, neurologic symptoms, or other concerning illness, tell your healthcare provider:
- That you had a recent tick bite or likely tick exposure
- When the exposure occurred
- Where you were hiking or traveling
- When your symptoms began
Do not rely on a commercial test of the removed tick to decide whether you need treatment. The CDC generally does not recommend routine tick testing for treatment decisions because a positive tick does not prove that transmission occurred, and a negative result can provide false reassurance.
In some circumstances, a healthcare provider may recommend a single preventive dose of doxycycline after a high-risk blacklegged tick bite in an area where Lyme disease is common. That decision depends on specific clinical factors, so preventive antibiotics should be discussed with a healthcare professional rather than taken automatically after every tick bite.
Note: Medical tests for tick-borne illness are not equally useful at every stage of infection. Diagnosis may depend on symptoms, exposure history, physical findings, timing, and laboratory testing. For illnesses such as suspected RMSF, clinicians should not delay appropriate treatment simply while waiting for test results.
When planning a longer trip, prevention is easier when your gear is organized and accessible. The article “Best Hiking Backpack for Multi-Day Trek” explains how to choose a pack for longer outdoor adventures, including space for essentials such as repellent, spare clothing, and a first-aid kit.

Frequently Asked Questions
What are ticks?
Ticks are arachnids that feed on blood. Some species can transmit bacteria, viruses, or parasites to people and animals while feeding, although not every tick carries a pathogen and not every bite causes disease.
Where are ticks commonly found?
Ticks commonly live in grassy, brushy, wooded, and leaf-littered environments and can also travel on animals. They can occur on hiking trails, in parks, in gardens, and around homes.
How can I avoid ticks while hiking?
Wear long clothing and closed-toe footwear, use an EPA-registered repellent labeled for ticks, consider 0.5% permethrin-treated clothing or gear, walk in the center of clear trails, avoid brushing against vegetation, and perform a thorough tick check after the hike.
Are there specific areas where ticks are more prevalent?
Yes. Tick species and tick-borne diseases vary across the United States. Blacklegged ticks are common across much of the East, western blacklegged ticks occur along the Pacific Coast, and lone star ticks are widespread across the Northeast, South, and Midwest. Local health departments can provide more specific information.
What should I do if I find a tick on my body?
If it is attached, grasp it close to the skin with clean fine-tipped tweezers and pull upward using steady, even pressure. Do not twist, jerk, burn, smother, or coat the tick with nail polish or petroleum jelly. Clean the bite area and your hands afterward.
How can I protect my pets from ticks while hiking?
Keep pets controlled on the trail, prevent unnecessary roaming through brush, check them carefully after outdoor activity, and use a veterinarian-recommended preventive product. Never use a dog tick treatment on a cat unless a veterinarian confirms that the product is safe for cats.
Do ticks jump or fall from trees?
Ticks do not fly or jump. Many ticks wait on grass, leaves, and shrubs in a position called questing and climb aboard when a person or animal brushes past. Focusing on contact with vegetation is more useful than worrying about ticks dropping from overhead branches.
Should I have a removed tick tested for disease?
Routine commercial tick testing is generally not recommended by the CDC for treatment decisions. A positive tick does not prove that infection was transmitted, and a negative result can provide false reassurance. Monitor for symptoms and contact a healthcare provider when appropriate.
