The ticks seem to go away, or estivate, or something from mid-July thru August. Our Parks and Lands peer review forest trip in 2019 was in southern Maine - Newcastle, Swan Island (with its huge deer population), Hebron and Skowhegan, 40 people walking in tick-infested areas in mid-August. I figured we would have a tick-pickin' horror show but, if anyone saw a tick, I never heard about it. (And I was responsible for listening and writing up the trip notes.) Since then, the tick-free Augusts have continued. My personal record was 26 deer ticks at the Topsham lot, but that was in late October. I was tossing them out the window as I drove up I-295 toward Augusta.
