No snakes yet at our place but I know they are there. Last year we had to kill a couple of Copperheads and a Rattlesnake. We use Ortho Snake B Gone around the coops and it seems to work pretty well. Skunks? This season was really bad. Hundreds of dead baby skunks on the roads. I don't miss them but they sure make a stink. No Raccoon yet this season either. Maybe having a bunch of dogs and geese works.
