I live in an expensive suburb right next to a wood. Field rats dug a tunnel under my garbage shed. Had to demo the shed and get a fully contained shed from Costco. Now, I have field mice that winter in my attic. Didn’t know brick homes have weep holes. I put a few jars of pepper mint oil up there. And filled the weep hole with copper wool. Not to mention the other critters that stop by like: squirrels, raccoons, skunks, chipmunks, groundhog, deers, stray cats, lizards, newts, shrews, and coyotes.
