When bats make their homes in residential areas, it can cause issues for both them and the homeowners. They are able to enter homes through gaps, cracks, missing shingles, and uncovered chimneys. Unfortunately, because bats prefer to live in colonies, if you see one, there are likely many others.
Besides actually spotting them with your own eyes, there are several other signs that can point to a possible infestation. They include scratching sounds behind your walls, screeching noises that sound as if they are coming from inside your home, and the appearance of bat droppings.
