Tick Season in Maryland
Active Season
April – November
Peak Danger
May – July
During peak months in Maryland, nymph-stage ticks (the size of a poppy seed) are actively feeding. These tiny ticks are responsible for most disease transmission because they're difficult to spot. Always do thorough tick checks after spending time outdoors, especially during May – July.
See month-by-month tick activity guide →Tick Prevention Tips for Maryland
- 1
Use EPA-registered tick repellent
Apply DEET (20–30%) to exposed skin and permethrin (0.5%) to clothing, shoes, and gear.
- 2
Wear protective clothing outdoors
Long sleeves, long pants tucked into socks, and light colors to spot ticks.
- 3
Do daily tick checks
Check your body, children, and pets after outdoor activities. Focus on the scalp, armpits, groin, and behind ears.
- 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
Maintain your yard
Keep grass short, remove leaf litter, and create a 3-foot gravel barrier between your lawn and wooded areas.
- 6
Protect your pets
Use veterinarian-recommended tick prevention year-round. Check pets daily for ticks.
