What noises will bats cause in the attic?

You lie in bed after a hard day’s work and try to close your eyes, only to start hearing strange sounds coming from the attic above you. Many homeowners have experienced this. The attic of the home is an easy spot for animals to invade. For one, they are mostly abandoned. Many homeowners just keep things they want stored away in the attic and rarely visit that part of the house. It therefore makes it easy for animals to stay there for an extended period of time without the homeowners noticing.

The trouble starts however, when their activities start to disrupt that of the owner. Bats are nocturnal animals; this means that they are most active at night when the homeowners are trying to sleep. The differences in sleep patterns between the bats and the humans can put quite a bit of tension on the cohabiting relationship. When bats are awake at night, they try to hunt for food and eat before retiring just before daybreak. Their activities can be heard from down below by people because it is especially quiet at night. If you hear the following noises in your attic, you most likely have a bat infestation.

One-Way Bat Exclusion; Bat Noise In Attic


Bats can scratch at your attic wall if they get stuck while trying to move around. They can also scratch if they find an animal like mice and they chase it around. Scratching noises can be very annoying for the occupants of a house. There is also the fact that scratching at walls can lead to structural damage to the house.


It’s not uncommon to hear squeaking noises coming out from the attic at night. Bats are silent flyers so you will most likely not hear them whilst they are flying. They can however cause squeaky sounds when they try to cross the attic. They may also be trapped within walls or air vents and you may hear them hitting the walls trying to escape.

As well as being a silent flyer, bats also make slight noises in the attic. They may be up in the attic for quite a while before being noticed. The major noise they make is as a result of colliding with objects or trying to get out of a crawl space. Bats transmit lots of diseases; therefore, you should act fast if you suspect that there might be bats in your attic. They are also colonial animals, preferring to fly in groups of two to over 100. You may therefore not be looking at one bat in your attic but a colony of them. This ultimately results in more damage and more cost of fixing up the space.
