Fine for deer but small rodents (mice/voles)may be even more important as vectors and the spray may not be able to de-tick them. I've read that one can put "traps" around one's yard - edge of woods preferable. Those traps are homemade, using cotton batting (or dryer lint, cheaper) with permethrin mixed in, then stuffed into cardboard tubes - TP centers work well, or paper towel cores cut in 2-3 pieces. Placed under a board so not ruined by rain, the material is eagerly collected by the tiny furbies as tick-killer nest material. Need to place them at about 10-ft intervals, and check weekly to see if they've been emptied.
Interior folks hitting their season averages.
Would need another 20"+, not impossible but very unlikely.
