Tips for trying to make your home less attractive to rodents
Picture this: You’re getting ready to snuggle up on the couch and binge-watch your favorite show. You head over to the fireplace to turn the gas logs on for some extra ambiance when a rodent runs across your hearth. Your evening’s probably shot, huh?
Well, like it or not, there is a chance of finding a rodent, whether it be a rat, squirrel or mouse, in your fireplace. The cooler temperatures of autumn and winter mean rodents may seek food, warmth and shelter in your home. And you might be surprised to learn they can find access points through your chimney or via cracks or holes in your mortar, whether you have a gas or wood-burning fireplace.
Learn what you can do to try to keep these rodents out, as well as who to call if you find rodents in your chimney.
