When to be most careful
Ticks are most active from spring through early fall. If you develop a rash or fever after a tick bite or after traveling to high-risk areas such as the Northeast or upper Midwest, tell your doctor.
How to protect yourself
- Use an EPA-registered insect repellent (such as DEET, picaridin, IR3535, oil of lemon eucalyptus, PMD or 2-undecanone).
- Treat clothing and gear with permethrin.
- Check your body, children and pets for ticks after being outdoors.
- Shower soon after coming inside, and tumble dry clothes on high heat for 10 minutes to kill ticks.
