How Do Bats Get In?
Although bats may appear large when in flight, they are not big creatures and can enter a home, whether accidentally or not, through very small spaces.
Usually, a bat will enter a building through a very small opening in or near the roof or chimney. Bats do not need a very large opening to get through; they can use an opening as small as ¼ x 1 ½ inch wide. If you have an older house, or storm damage to a newer house that has not been addressed, it is common to find holes this large leading in to your home.
An opening that is frequented by bats, and therefore needing immediate attention, will usually have “rub marks”. The entry point will have a smooth, polished appearance and be stained. The stain is from the oils from the bats’ fur mixed with dust. If you have noticed one or more “rub marks” on your home or other structure, you may have an opening which has been used heavily by bats, indicating a roosting point of large numbers. You should call a Wild Animal Management expert to diagnose the problem right away.
If you have a bat in your house, your best bet for getting rid of bats that you can’t seem to control is to call a professional in to do the job for you. A professional animal control company can exclude them from the premises and make sure they can’t get back in, while thoroughly cleaning the biohazardous droppings that they leave behind. Experience counts when working on bat jobs, and it takes a skilled eye to get the job done right the first time.
