As average temperatures climb, ticks are expanding their reach and becoming more active for longer parts of the year. Experts warn that warmer winters and earlier springs are changing tick behavior and increasing the risk of bites for people and pets. Knowing where ticks hide, how to avoid them, and what to do after a bite can reduce your risk of infection.
Why milder climates favor tick growth and spread
Ticks thrive when winters are mild and humidity is sufficient. These conditions help their eggs hatch and their juvenile stages survive.
Lifecycle and weather links
- Ticks progress through egg, larva, nymph, and adult stages.
- Mild winters raise survival rates for off-season stages.
- Longer warm seasons mean more time for ticks to feed and reproduce.
Range expansion and new hotspots
- Warmer temperatures push ticks into northern and higher-altitude areas.
- Suburban growth and fragmented forests increase human exposure.
- Deer and small mammals transport ticks into populated zones.
Diseases carried by ticks and what to watch for
Ticks transmit a range of bacterial, viral, and parasitic infections. Early recognition improves outcomes.
- Lyme disease — fever, fatigue, headache, and a bullseye rash in some cases.
- Anaplasmosis — flu-like symptoms and low white blood cell counts.
- Babesiosis — malaria-like symptoms; can be severe in older or immunocompromised patients.
- Other pathogens include ehrlichiosis, Powassan virus, and Rocky Mountain spotted fever.
If you develop fever, rash, or unexplained fatigue after a tick bite, contact a clinician promptly.
Proven ways to protect yourself outdoors
Simple habits cut your exposure to ticks during hikes, yard work, and play.
- Wear light clothing so ticks are visible.
- Tuck pants into socks and shirts into pants in tick-prone areas.
- Use EPA-registered repellents containing DEET, picaridin, or IR3535.
- Apply permethrin to clothing and gear only, not to skin.
- Walk in the center of trails and avoid tall grass and brush.
Daily tick checks after being outdoors reduce the chance a feeding tick transmits infection. Showering within two hours can help remove unattached ticks.
How to remove a tick safely and what steps matter most
Removing a tick quickly and correctly lowers infection risk.
- Use fine-tipped tweezers to grasp the tick as close to the skin as possible.
- Pull upward with steady pressure. Do not twist or crush the tick.
- Clean the bite site with soap and water, iodine, or rubbing alcohol.
- Save the tick in a sealed bag or container if testing is needed.
- Remove a tick within 24 hours when possible; this greatly reduces risk for Lyme disease.
Protecting pets and managing your yard
Pets bring ticks into the home. Combine treatments and landscape changes for the best protection.
- Talk to your vet about monthly oral or topical preventives and tick collars.
- Check pets daily and remove ticks quickly.
- Keep lawns mowed and remove leaf litter and brush near the home.
- Create a gravel or wood-chip buffer between lawn and wooded areas.
- Consider professional yard treatments in high-risk locales.
When to see a doctor and testing options
Not every tick bite needs antibiotics. Clinical judgment depends on risk factors and symptoms.
- Seek care if you notice a fever, rash, joint pain, or flu-like illness after a bite.
- Bring the removed tick if possible to help identify species and infection risk.
- Blood tests for Lyme and other tick-borne diseases may be ordered based on symptoms and timing.
- Some doctors prescribe preventive antibiotics in selected high-risk bites.
Public health steps and community guidance
Local health agencies track tick-borne disease trends and advise the public on prevention.
- Stay updated on local tick maps and seasonal alerts.
- Support neighborhood efforts for deer and rodent control when appropriate.
- Encourage schools and parks to maintain trails and remove tick habitat.
- Report suspected tick-borne illnesses to help improve surveillance.
