No. 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. Ticks are active whenever temperatures are above freezing, particularly over 40 degrees Fahrenheit.
