The presence of bats in your house may seem harmless, given their reputation for being cute, spooky, and harmless creatures. However, having bats in your home poses various health hazards, such as the transmission of diseases through their feces and saliva. Therefore, it is crucial to identify the signs of bat presence in your home to prevent health risks and call for professional help immediately. In this blog, we’ll discuss the common signs of bats in the house and how to identify them.

Bat Droppings

Bat droppings, also called guano, resemble mouse droppings but are larger and have a distinctive musky odor. These droppings are usually found in a concentrated area, such as walls, ceilings, and attics. They may pose a health risk as they contain Histoplasma capsulatum, a fungus that can cause respiratory infections. Therefore, if you notice bat droppings in your house, it is crucial to seek professional help to remove bats from your home.

Dark Spots on Walls and Ceilings

Bats tend to leave dark spots as they move around walls and ceilings in search of food, water, and shelter. These spots may be a result of their oily fur leaving behind stains wherever they go. If you notice dark spots on the walls and ceilings, especially near the attic, it could be a sign that you have a bat infestation in your home.

Unusual Noises

Bats are nocturnal creatures and usually fly out of their roosts at night to hunt for food. If you hear rustling noises or high-pitched squeaking sounds coming from your walls, ceilings, or attic, it could mean that bats have made their home in your house. These noises usually occur at night and are a sign that you need to call in bat removal professionals to get rid of the bats.

Bat Sightings

One of the most obvious signs of bats in your home is spotting them in or around your property. Bats usually enter your home through open windows, doors, or cracks in the walls and can be seen flying around your house during the night. While bats are not harmful, their ability to transmit rabies to humans makes it necessary to remove them from your home immediately when sighted.

Strong Odor

Bat droppings and urine can produce an unpleasant odor that can permeate your home and become persistent if left unaddressed. This odor usually worsens as the volume of their feces and urine increase, hence the need to seek professional bat removal services before the infestation worsens.


Identifying the common signs of bats in your house is crucial in preventing the potential health hazards they pose. If you notice any of these signs in your home, it is essential to seek professional help from bat removal experts rather than trying to remove them by yourself. Remember that bats are protected wildlife and removing them improperly or without permission may result in legal penalties. Stay vigilant and keep your home bat-free to stay healthy and safe.
