Four Signs Of A Bat Infestation

Posted on

Bats are a common household pest whose presence can be quite disrupting, as they can carry diseases and cause structural damage to your home. Understanding some of the early warning signs associated with a bat infestation can help you identify the problem early so that you can have it dealt with by a professional before any serious repercussions come about.

Black Spots

If you notice that there are black or brown stains on certain areas of your home, especially around chimneys, vents, or any other openings on your roof, siding or exterior, you may have bats present within your homes. These stains are caused by the dirt and grease present on a bat's body fur rubbing against your home as they enter and exit every night. These stains will also point you to which areas of your home will have to be repaired in order to prevent future bat populations from taking up residence.


Another clear indication that you have bats in your home is if you notice guano buildup either in your attic or another room in your house, or in the area around your roof and yard. Guano is bat feces and is usually quite noticeable in that it is a strong smelling, white substance that will harden over time, creating a layer of excrement that can be hard to remove and can cause damage to your home if left alone for too long.


Another fairly clear indication that you have bats living in your attic is if you notice that there are strange noises and sounds coming from behind the walls or in the ceiling. Bats will squeak to communicate, and will also scratch at wooden structures as they move around and roost. These sounds will become most prevalent around sundown and sunup, as they leave and enter your home, respectively, though you may notice some activity throughout the day depending on the size and severity of your bat problem.

Strong Smells

If you notice that there is a strong earthy and pungent smell coming out of your attic, crawlspace, or other areas in your home, you may have bats sleeping there during the day. Keep in mind that a strong and unpleasant smell can point to a number of different issues, from multiple types of pests to mold growth to a simple lack of ventilation – so keep an eye out for the other warning signs on this list to determine if bats are too blame.
