We often get calls from people that they can “hear bat sounds” in their home. Believe it or not, bats are actually very quiet animals. Most people do not know they have a colony of bats living in their attic until they see signs of guano scattered about their home or have one accidentally wind up in their living room.

Bat sounds are indicative of a larger scale problem. Once they get to the point where you can hear them, you most likely have more of a problem than you may realize.

3 Signs You Can Spot Before Hearing Bats

Before hearing the tell tale squeaks and scratching noises bats can make, there are three things you can spot beforehand.

  • Bats flying around outside your home – It is perfectly normal and natural to see bats flying around outside at night foraging for food and water. What is not normal is seeing bats constantly hanging around close to your house. Homeowners will sometimes report bats hanging on their fences, the eaves of their house, or on a porch or balcony. If you are uncertain if there are just bats hanging around or if they are actually living inside your home, set up a “twilight watch”. At sunset, take a lawn chair outside, sit down, and look up at your house. Just sit back and watch for bats leaving their roost for the night. If you do have bats in your house that’s one way you may see them.
  • Unexplained stains on walls and ceilings – If bats are roosting in your walls or attic, stains from bat urine may be found on the walls or ceiling. Bat urine also has an unpleasant odor… One particular lady I spoke with said, “Oh, so that’s what the wet spot is on my ceiling. I wipe it off every week and every week it comes back.”
  • Rub marks on the outside of the building around areas with holes or cracks – Bats carry oil and dirt on their fur. As they are entering or exiting your home over time they will leave this oil and dirt behind. Giving your home a tasteful “dirty” look.

I Think I Hear Bat Sounds in My House

We recently posted a blog about Chimney Swifts. These are noisy little birds that people often mistake for bats in the chimney. We have a great audio file of some Chimney Swifts we found on an inspection last month. Check out our YouTube channel here to listen to that.

Bat sounds are easy to mistake as being something else. Most people think they are mice or even roaches. Listen to one homeowners audio of bats in his walls here. https://youtu.be/q4t704ShqaA

If you aren’t sure if your sounds are bats, birds, or mice we are happy to come investigate for you.
