You may be asking, are ticks getting worse? In much of the United States, the answer is yes.

tick activity is expanding into more places, staying active for more months, and exposing more people to tick bites.

Warmer winters, changing wildlife patterns, and growing awareness all contribute to the trend.

Are Ticks Getting Worse? What’s Driving the Rise

You can lower your risk by avoiding brush and tall grass, using an effective repellent, checking your clothing and skin, and removing attached ticks promptly.

The Centers for Disease Control and Prevention recommends reducing tick exposure as the best defense against tick-borne disease.

Why Tick Activity Is Expanding

Climate change affects tick survival, seasonal timing, and geographic range.

Acorns, mice, chipmunks, deer, and other hosts also shape local tick populations, while several tick species now appear in regions where you may not have expected them.

Warmer Winters and Climate Change

Ticks thrive when temperatures and moisture stay within a suitable range.

Warmer, shorter winters allow more ticks to survive and become active earlier in spring or later in fall.

You may encounter ticks during mild winter days, especially in leaf litter, wooded areas, and protected vegetation.

The pattern varies by location and species.

In the Midwest, including Ohio, changing temperatures help blacklegged ticks expand or remain active longer.

A longer tick season means more opportunities for outdoor exposure, even outside traditional peak months.

Acorns, Mice, Deer, and Other Hosts

Tick populations depend on animals that provide blood meals and transport.

Acorn-heavy years support larger populations of mice and chipmunks, which feed immature blacklegged ticks.

When those young ticks mature, they can transmit pathogens to people.

Deer help adult deer ticks move through landscapes and reproduce.

Birds, rodents, pets, and other wildlife can also carry ticks into new areas.

New Regions and Changing Tick Species

The blacklegged tick, also called the deer tick, is strongly associated with Lyme disease in the eastern and north-central United States.

Lone star ticks have expanded their range and may cause several illnesses, including alpha-gal syndrome.

Longhorned ticks have also established populations in parts of the United States.

A changing mix of tick species can alter your local risk.

Distribution maps from the CDC’s tick information show general ranges, though ticks may occur outside mapped areas.

Health Risks Beyond Lyme Disease

Lyme disease receives the most attention, yet it is only one of several tick-borne diseases and vector-borne diseases affecting people in the United States.

Your symptoms can vary by pathogen, tick species, location, and how quickly you receive care.

Symptoms That Need Medical Attention

Seek medical advice if you develop a spreading rash, fever, severe headache, unusual fatigue, muscle aches, joint pain, swollen glands, confusion, or flu-like symptoms after a tick bite.

Symptoms may appear days or weeks later, and you may not remember being bitten.

Ehrlichiosis, anaplasmosis, babesiosis, and Rocky Mountain spotted fever can become serious without timely treatment.

Powassan virus is rare but may cause severe neurologic illness.

Tell your clinician when and where you may have encountered ticks.

Diseases Linked to Different Ticks

Blacklegged ticks can transmit Lyme disease, anaplasmosis, babesiosis, and Powassan virus.

Lone star ticks are linked to ehrlichiosis, Rocky Mountain spotted fever in some regions, and alpha-gal syndrome, an allergic reaction to a sugar found in many mammalian products.

Tick-borne illnesses do not always produce a bull’s-eye rash.

The absence of a rash does not rule out disease, so your symptoms and exposure history still matter.

Why Fast Tick Removal Still Matters

Ticks may need time to transmit certain pathogens, so prompt removal reduces risk.

Use fine-tipped tweezers to grasp the tick close to your skin and pull upward with steady pressure.

Clean the bite area and your hands afterward.

Avoid burning the tick, covering it with petroleum jelly, or twisting it unnecessarily.

Record the date and location of the bite, then monitor your health.

The CDC’s guidance on tick bites explains removal and follow-up steps.

How to Lower Your Household Risk

Effective tick prevention combines yard maintenance, protective clothing, repellents, and a consistent tick check.

You can reduce contact without avoiding every outdoor activity.

Make Your Yard Less Tick-Friendly

Keep grass trimmed and remove leaf litter, brush, and unnecessary ground cover near play areas and outdoor seating.

Create a dry barrier of wood chips or gravel between lawns and wooded edges, and keep firewood neatly stacked in a sunny, dry location.

Discourage deer and rodents from entering your yard by securing trash, cleaning up spilled birdseed, and choosing deer-resistant landscaping.

Yard changes reduce favorable habitat, though they cannot eliminate every tick.

Choose Repellents and Treated Gear

Use an EPA-registered repellent containing DEET, picaridin, IR3535, oil of lemon eucalyptus, or OLE, according to the label.

Do not use OLE products on children younger than three years old.

Permethrin-treated clothing and gear can provide additional protection during hiking, gardening, or yard work.

Follow product directions, and check the Environmental Protection Agency’s repellent guidance for registered options and safe use.

Do a Thorough Tick Check

After time outdoors, inspect your clothing, gear, pets, and body.

Pay close attention to your hairline, scalp, behind your ears, armpits, waist, groin, backs of your knees, and between your toes.

Place clothing in a hot dryer before washing when practical, since heat can kill ticks.

Showering soon after coming indoors may also help remove unattached ticks.

What to Do After Finding a Tick

Remove an attached tick as soon as you notice it. Clean the bite site.

Take a clear photograph of the tick. Save the tick in a sealed container if a healthcare professional asks for identification.

Write down where and when you found the tick. Watch for symptoms during the following days and weeks.

Contact a clinician if you develop symptoms such as fever, rash, severe headache, breathing difficulty, or unusual weakness.
