"An even wetter winter is expected to follow a record-setting hot and wet summer in the Northeast and New England, which is expected to cause ticks to remain active longer than normal."
Just anecdotally, I stopped wearing my permethrin treated clothes about two weeks ago and haven't gotten any new bites, even though i have ventured into the underbrush almost daily. Haven't seen a tick in weeks.
Saw this article a few days ago

Losses in midsummer, when these insects are most numerous, exceeded 80 percent."
