A few summers ago, your whole family probably got a good laugh about the bat in the house that dad had to chase and catch while wearing his bathrobe. It was funny after the fact recanting mom running screaming from the room.

The summer after that, dad wasn’t quite as amused about having to capture another one in the middle of the night. And he really wasn’t amused when he had to catch another one a couple days later.

It’s spring now and there’s already been one in the living room. Dad’s not a happy camper and mom is petrified of the growing problem.

The logical question at this point is why do bats keep coming in my house? We have an answer, but you might not like it.

Multiple Bats in my House

One random bat in the house doesn’t always mean anything. Most of the people that call us have had at least two or three instances of bats in the house over the last few years though. Multiple bats in your house is a very strong indication of an infestation.

Most bat colonies found in houses are maternal colonies. Each mother bat gives birth to one pup each year, although sometimes twins are born and some species (though not many) give birth to more than one a year.

What this means is that each year the bat colony living in your attic or walls is roughly doubling. By the time most people start seeing bats inside their living space, the bats have been roosting in your home for at least a few years. By the time most people realize there is a problem the colony is anywhere from 20 bats to a few hundred bats in size.

That’s the easy answer to why do bats keep coming in my house. To explain in a little more detail, there are a few other factors that drive a bat inside instead of outside:

  1. Weather – If it’s been raining for days on end, the bats are likely to not want to go outside. They will be getting up and moving around and exploring for lack of a better way to put it. They may wander inside your living space. The other circumstance is if in the transition time between seasons, especially winter to spring, it gets warm and then cold over and over. The bats sense the temperature to decide when to wake up or go to sleep around hibernation season. This up and down pattern tends to confuse them and as they are disoriented, we get a lot of calls about bats inside homes.
  2. Pup Season – Remember being a young, dumb teenager? Most mammals go through that stage and bats are no exception. When pups are first learning to fly, they stick close to mom. As they get a little older (teenager) and braver, they venture off on their own. They just aren’t as smart as they think they are and often get turned around and end up inside your home instead of outside with the rest of the colony. Sounds about right for a teenager, huh?
  3. Colony Size – This one confuses people sometime. So as simply as I can put it, sometimes a colony outgrows the small space they are living in and they need to find more room. If they are in your attic this may mean they find a way down an inside wall cavity. As this is unfamiliar territory, they end up in weird random places like the first floor of a two-story house or in the basement. Bats like to be up high and it’s not normal for them to be found in these lower areas of your house. This may be an indication that the colony is quite large and outgrowing their current roosting space.

What’s the Next Step

We know that wasn’t the answer you wanted to find, but it’s not the end of the world. We encourage all of our customers to do a twilight watch and see if bats come flying out of your house. That’s the best (and totally free) way to know for sure. We are also happy to come do an inspection and get you a proposal to handle the problem once and for all.

Don’t sit and wonder why bats keep coming in my house. We can help you fix this issue once and for all. Call our customer service to set up an inspection at 877-264-2287 or click the button below and we’ll call you.

    Hello. I remember a bat in a house when I was younger. Tonight, I had the 2cnd bat in my house within a couple months. This one tonight seemed to be a larger/adult size bat. I believe it was coming from the basement tonight...... although, the last time I am not sure because it was in the middle of the night. Do you suppose I should get up before daybreak and perch outside to see if any bats leave from my my area? I have lived here for 9 years and never had any problems before. I live in an old farmhouse with a basement and an upstairs (plus an attic.... of course). Would appreciate any information possible to help with my situation so it will not get outta control. Thank you.

      Hi, Sometimes the "bat watch" at dusk is very beneficial, however where you live and how cold it is right now will greatly affect the results this time of year, even possibly making the watch irrelevant. I highly recommend that you call our customer service number at 877-264-2287 for more information. They can give you some good guidance on how to proceed with the information you have.

      Hi, yes, we can help. Having that many bats in indicates that it is likely that you have a bat infestation somewhere in the house. We can send a technician out to inspect around your house and find the spot that is likely their entry/exit. Please call our customer service number and we can give you more information. 877-264-2287
