This summer I had some major issues with bats, raccoons, and mice. Since then I have had someone come out from here to treat my home to ensure that pests like this dont keep coming back. That was almost 2 months ago and I have not had a problem since. I have not seen any of these critters or any other one come back or cause an issue for me like they did before. You would be smart to have them critter proof your home as well.
