Does tick season in Maine end during the summer?

Tick season in Maine typically peaks between May and July, and again in October and November, according to the Maine Center for Disease Control and Prevention.

Human encounters with the two most common species of ticks in Maine — the deer tick and the American dog tick — tend to decline in August and September; the majority of human Lyme disease cases are reported in June and July.

Deer ticks, which spread Lyme disease, go through three life stages: larva, nymph and adult. Nymphs peak in activity in June and July. Adult deer ticks are most active in the spring and again in mid- to late fall. Tick larvae rarely bite humans.

Adult American dog ticks, which are unable to spread Lyme disease to humans, are most active from April to August.

The Maine CDC notes that ticks are active whenever temperatures are above freezing, particularly over 40 degrees Fahrenheit.
