Tick Season in New Hampshire

Active Season

April – November

Peak Danger

Tick Prevention Tips for New Hampshire

  1. 1

    Use EPA-registered tick repellent

    Apply DEET (20–30%) to exposed skin and permethrin (0.5%) to clothing, shoes, and gear.

  2. 2

    Wear protective clothing outdoors

    Long sleeves, long pants tucked into socks, and light colors to spot ticks.

  3. 3

    Do daily tick checks

    Check your body, children, and pets after outdoor activities. Focus on the scalp, armpits, groin, and behind ears.

  4. 4

    Shower within 2 hours

    Showering after coming inside can wash off unattached ticks and is a good time to do a tick check.

  5. 5

    Maintain your yard

    Keep grass short, remove leaf litter, and create a 3-foot gravel barrier between your lawn and wooded areas.

  6. 6

    Protect your pets

    Use veterinarian-recommended tick prevention year-round. Check pets daily for ticks.
