One way to get rid of mice is by eliminating all possible entry points into your home. While it won’t help any current infestations it will stop any new mice from getting in and starting the process all over again. To do this, look for any cracks or holes on the exterior of your home and seal them with caulk or steel wool. Avoid using plastic, rubber, wood, or anything else mice can easily gnaw through as sealants. Get weather stripping for door and window gaps and make sure the sweep on your door creates a seal against the threshold when it’s closed. Mice can squeeze through some pretty small spaces, so make sure to check all nooks and crannies!
