Ticks bite when they are active, so your risk depends on temperature, moisture, habitat, and outdoor exposure rather than a specific calendar date.
In much of the United States, tick season is busiest from spring through fall. Many areas see especially frequent tick bites in late spring and summer.

You can still encounter ticks during mild winter weather. A quick tick check after outdoor time makes sense in any season.
Different ticks become active at different temperatures. Warm regions may have tick activity nearly year-round.
A bite does not automatically mean you will develop a tickborne disease. Prompt removal and symptom awareness help reduce risk.
Active Seasons, Weather, and Daily Exposure

Your local tick season changes with climate and species. Warm, humid conditions and time in vegetation raise exposure, while dry heat can reduce activity near the surface.
Why Spring Through Fall Is Often the Highest-Risk Period
In many U.S. regions, ticks become more active as temperatures rise in spring. Nymphs, which are very small and hard to spot, often create substantial exposure during late spring and summer.
Adult ticks may become more active again in fall. You are more likely to encounter ticks when hiking, gardening, camping, or walking through leaf litter, brush, and tall grass.
The Centers for Disease Control and Prevention’s tick guidance recommends exposure reduction to help prevent tickborne diseases.
Why Ticks May Be Active Outside the Usual Season
Ticks do not follow fixed start and end dates. In northern states, some adults become active during warm winter days.
Southern states may see activity for most or all of the year. Snow cover, freezing temperatures, dry conditions, and local habitat can limit activity.
A stretch of mild weather can bring ticks out earlier in spring or keep them active later in fall. Adjust your outdoor habits to local conditions rather than the calendar.
Do Ticks Bite at Night?
Ticks can bite at night. They do not need daylight to attach.
Evening exposure can happen when you camp, walk through vegetation, or bring ticks indoors on clothing or pets. Nighttime checks are especially useful after outdoor activities.
Use a bright light to inspect your skin, clothing, gear, and pets before sleep.
Where and How Tick Encounters Happen

Your risk rises when you enter tick habitat or brush against vegetation. Ticks often crawl upward after reaching you, so checking promptly can help you find a tick before it remains in place for long.
Risky Habitats and Outdoor Activities
Wooded areas, grassy areas, leaf litter, brush, and overgrown yard edges can support ticks. You may encounter them while hiking, hunting, gardening, camping, mowing, or playing with pets near vegetation.
Staying on cleared trails helps limit contact, though it does not eliminate risk. Ticks can also live close to homes, especially where lawns meet shrubs, woods, stone walls, or piles of leaves.
How Ticks Reach People and Pets
Ticks do not jump or fly. They wait on grass, shrubs, or leaf litter and attach when you brush past.
After reaching your clothing or skin, a tick may crawl for some time before finding a feeding site. Pets can carry ticks indoors on their fur.
Check dogs and cats after outdoor time. Ask your veterinarian about appropriate tick prevention for your pet.
Body Areas to Check After Outdoor Time
Inspect your socks, ankles, legs, waist, groin, and underarms. Also check your scalp, hairline, behind your ears, and the backs of your knees.
A shower can help remove unattached ticks. Use a mirror or ask someone you trust to inspect areas you cannot easily see.
What To Do After Finding an Attached Tick

Remove the tick promptly and carefully. Clean the area, record when and where you noticed the tick if possible, and monitor yourself for a rash, fever, or other symptoms.
How To Remove a Tick Safely
Use fine-tipped tweezers to grasp the tick as close to your skin as possible. Pull upward with steady, even pressure until the tick releases.
Do not twist, crush, burn, or cover the tick with petroleum jelly, nail polish, or other substances. After removing a tick, clean the bite site and your hands with soap and water or an alcohol-based cleanser.
If mouthparts remain in the skin and you cannot remove them easily, leave them alone and let the skin heal. Save the tick in a sealed container if your healthcare provider recommends identification.
Skin Care and Symptom Monitoring
Mild swelling, itchiness, or redness can occur at the bite site. A small spot that fades within a day or two is often a local reaction.
An expanding rash deserves medical advice. Watch for fever, chills, headache, fatigue, body aches, muscle pain, joint pain, swollen lymph nodes, or other flu-like symptoms during the days and weeks after the bite.
Not every tick carries a pathogen, and an attached tick does not guarantee Lyme disease or another tick-borne infection.
When To Contact a Healthcare Provider
Contact a healthcare provider if you develop an expanding rash, fever, or other symptoms after a bite. Mention when and where the exposure occurred, how long the tick may have been attached, and whether you identified the tick.
Seek medical advice if you notice symptoms that could indicate Lyme disease, Rocky Mountain spotted fever, ehrlichiosis, tularemia, or tick paralysis. Seek emergency care for signs of an allergic reaction or anaphylaxis, such as trouble breathing, facial swelling, faintness, or widespread hives.
Reducing Risk During Outdoor Time

You can lower exposure with repellent, protective clothing, smarter trail choices, and consistent checks. These habits matter during peak tick season and on mild days outside the usual seasonal window.
Repellents and Clothing That Help
Apply an EPA-registered insect repellent according to its label. Products containing DEET protect exposed skin, while permethrin-treated clothing and gear help repel or kill ticks on fabric.
Wear light-colored pants, long sleeves, and closed shoes when practical. Tuck pants into socks during higher-risk activities, and follow product instructions for children, skin, clothing, and pets.
Habits for Trails, Yards, and Pets
Stay near the center of cleared trails instead of brushing against tall grass or overgrown edges. In your yard, remove leaf litter, keep grass trimmed, and create a clear barrier between lawns and wooded areas when feasible.
Check pets after walks and use veterinarian-recommended prevention. Ticks can enter your home on animals, clothing, backpacks, and outdoor equipment.
Post-Activity Checks That Catch Ticks Early
Check your clothing and gear before you go indoors. If the fabric allows, put worn clothing in a hot dryer.
Shower soon after outdoor activity to remove unattached ticks. Use this time to do a full tick check.
Look over your entire body, including hidden skin folds, scalp, hairline, and behind your ears. If you find a tick, remove it promptly and watch for symptoms of tickborne diseases.
