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.

    We have bats living the crawl space above both bedrooms of our 2-story addition. They are interlocking tile drop ceilings. The bats are accessing area through a whole house can aluminum dome bent on the roof that the roofer failed to reinstall the screening on. Been up there about 5-6 yrs. I installed a steel mesh cage over the vent with a one way bag valve and witnessed 5 bats exit at dusk tonite. I have done due diligence in sealing up alternate gaps. How long should I wait to seal up the valve and can bats re-enter through these “one-way” valves?

    • Tori Bruce

      September 6, 2021 | Reply

      Hi, we recommend leaving the one way device up for at least a week with at least 3 days in a row with no rain and above 40 degrees. If the valve is installed properly, bats should not be able to enter. Many times you'll see them hanging around right outside it because they are persistent.

    I found a dead bat in my cellar. Nothing else, no sightings. Walked around the finished cellar, no sighs of urine or droppings that I can see. I have spaces where they could get inside the house. What do I do from here, wait and see if I see more?

    • Tori Bruce

      So it either flew in an open window or door and ended up down there (we hope it's this scenario), or there is a colony using the "spaces" to get in and this one got lost on the way out. We recommend doing a watch outside your house at dusk. If bats are using your home as their home, they will leave to eat at dusk, and hopefully you would see them. It sounds like you looked for signs of guano inside but also look for signs outside directly under the openings you mentioned.

      Hello, I'm sorry about your urgent bat situation. If you think your child or pets have been in the same room with the bat, you should call the child's pediatrician and ask for direction. I am unclear if the bat is still in your house, but if it is and you think there is any chance that it came into contact with anyone (including pets), you should try to capture it and contact animal control. We are an exclusion company for when people have a colony of bats, but we do not remove single bats that may have flown in through an open door or window.

    We see a small amount of what we think is bat droppings in the same place on our porch off and on. Sometimes a couple days in a row and then it may be 4-6 days without anything. Where the droppings are on the floor, there is no holes above. Do you think we have bats inside?

    • Tori Bruce

      July 7, 2021 | Reply

      It's always possible that they are inside, but they would need an exit of some sort. You could do a watch at dusk to see if you spot them leaving (they will leave every night). Another possibility is that they find your porch safe and comfortable for a temporary resting spot, but it's not where they spend their days. If you feel certain you are dealing with bats and would like more help, please don't hesitate to call our knowledgable customer service team at 877-264-2287.

    Do you have any suggestions for people who have done bat excursion and still have a problem? I live in Michigan. We paid 2 companies to seal up the entrinces/install one way doors, and clean up our attic. After the first company failed to fix the issue 3 years, we gave up on our warranty and called a, hopefully, more competent company. Last year was the first we didn't hear bats in our walls. As soon as I said I think they fixed the problem... we had another bat. They seem to be roosting on our front and back porches, so I haven't ruled out that one came in as we brought our dog in from outside. We are exhausted though, this has been a long process of 4+ years, and really expensive. We will have the company out again to check for gaps. Is there anything that can be done to make a house less desirable?

      I'm so sorry you've had such a long and difficult experience having your bats excluded. I would guess you had a very established colony and they spent enough time there that they are quite determined to get back in. Since they can't get in, they are settling for your porches. (this blog has some tips for moving them away from the porch https://www.getbatsout.com/a-bat-on-your-porch/ ) Bats instinctively desire to have their babies in the same place that they were born, and they live a long time so they will keep trying year after year. Bat exclusion is expensive! It's important to hire a company with lots of experience and one that offers warranty on their work. Sounds like you made very good effort on both of those points. There are things like home maintenance or really bad weather that can undo the exclusion technicians work. I really hope you are correct and your bat was brought in or flew in from the porch!

      If you've never had one before, it likely flew in an open door or window. However if more show up, you might have a bigger issue. It is a good idea to consult with your physician if you think there was any chance it was in the room with someone sleeping, or with children, or someone disabled.

    I have lived in my 120 year old house for 15 years. Over the years I've had anywhere from 2-3 bats in the house to none for years at a time. I've had a "bat expert" at the house who couldn't find a roosting spot. Just this week I've had 3 bats. One was unable to fly, but I'm not sure whether it was injury or illness. I should have called Animal Control but didn't. I'm now 70 years old & it is getting hard to help them get outside once I find them flying around the house. What do you suggest?

      From what you've said, it does sound like you have a bat colony. Our best recommendation is to bring in a new bat expert, as frustrating as that may be, perhaps a new set of eyes will find what the other fellow missed.

        I had a single bat get into my apartment about 2 months ago I called my landlord and it was removed. My wife just called tonight and said another one came through by our vent. That’s 2 bats within 2 months. Should I be concerned? My landlord had terminix come and patch up all the holes on the outside of the building after the first bat got into our apartment.

          If they sealed up the holes without installing one way exit devices, they very likely trapped the bats inside. Which is terrible in all respects because the bats will be desperate to get out (and may wander into the living space) or they just killed a colony (bats are endangered so you are always supposed to "exclude" not "exterminate".) If your landlord hired a company that deals specifically in bats, they would also be concentrating on clean up of guano to keep all the tenants safe from histoplasmosis.

    Live in upstate ny - Albany area- live in downtown area 100 year old brownstone-3 stories-have had bats in house over the past few years. Mostly one-offs- been very hot this summer and we had a few bats over the months- hired a bat control person who recently “sealed” the outside of the building- wire meshed the chimney - have had two bats in past two days.

      Sounds like they may have trapped them in. The bats are now desperate to find a new way out. Hopefully I'm wrong and they installed one-way doors because bats are endangered so a reputable company would never trap them in (which would kill most of them).

    I live in upstate NY and about 2 months ago I found a bat in my upstairs bedroom, I thought it flew inside when I went to go let the dog out and figured it was a fluke, tonight I found another batt flying around my house and never seeing a batt before 2 months ago I felt something must be going on that I now have seen 2 bats with in 2 months and figured they must be getting in somewhere. And then I read your story about the colony and hope that’s not the case. If it was a colony does it make sense this time of year that I would see 2 bats with in 2 months? I’m gonna check out the roof and see where they could be getting in, I don’t have an attic tho so my thoughts is they may be living in my basement.

      This is definitely bat busy season. So, yes, this is when bats will be most likely spotted inside homes. If you are going to do an outside inspection, watch for signs of guano (very similar to mouse droppings) and urine staining (or an ammonia-like odor), sometimes that is an indicator of where they come and go out of the house.

      July 30, 2020 | Reply

      It's possible that a bat can fly in through an open door or window. But if you have more than one sighting, the chances are greater that you may have a colony residing in your house. The first step would be examining the perimeter of your home, even having someone get up on the roof and look around. There are usually signs (guano or staining from urine) of where bats are entering and exiting. You can even do an evening watch, as it is dusk, bats will exit to eat. If you find the entry you need to bat proof WITHOUT trapping the bats inside. They are endangered and so you have to be very careful to not kill them. We would be so happy to tell you more or help you accomplish those steps if you call our customer service number. 877-264-2287

    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.
