If I find one bat in my house does that mean there's more?

Bats are peaceful animals. They are so quiet by nature that they can live in your house for a long time and not be discovered. Most bats love to crawl in between walls of houses where the temperature is not too hot or cold.  They are nocturnal animals therefore they only come out at dusk when you are likely not to see them. There are times, however, that you may see a bat flying around in your home, then you may begin to wonder if there are more bats taking abode in your attic or walls. There are many factors that determine if the bat you found is alone or is part of a colony living in your house.

The season

The first of those factors is the season of the year. During mating season, bats are usually with other bats roosting together until the female bats become pregnant. Once this happens, the male bat usually leaves during the maternity season and wanders off on its own or with a group of other males. During this season, it may venture into your home alone and be discovered by you. Similarly, the bat may fly into your house with a gang and form a colony in your attic or walls. The female may also leave its abode in search of adequate space to raise its young and locate your home in the process.

Bats Nesting

If you have invited them in

Sometimes, you do not have a bat problem. You simply have left a window or a door open and a bat entered through it. If this is what has happened, then the bat can quickly be relocated outside. When you spot a bat, it is better to avoid letting it stay inside as bats emit a unique scent that attracts other bats to your home. Before you know it, you will be dealing with more bats than you bargained for.

How can you tell if there are more bats?

If you see a bat flying around in your home, there is always the possibility that there is more. However, you won’t know for sure until you check. Use the guide below to help you in your search.

Search for dark abandoned places

Bats love to roost in dark places because they are extremely sensitive to light. When searching for bats, visit dark places you do not normally visit in your home such as the attic, top of high shelves, inside the walls of the chimney, edges where two walls meet, and so on. They can sometimes venture into the basement so be sure to cover that area too.


This is an obvious sign of a bat infestation. When you see bat droppings around your home or in hidden places, then it’s most likely that you have a bat infestation. Bat droppings are black in color and look like mouse droppings. They are, however, slightly bigger. Check your walls and ceilings for traces of bat urine as their urine may also stain walls and ceilings.

Sounds coming from the attic

Bats live a quiet life but sometimes you may hear them at night while they are trying to go out to hunt. They may also make scratching noises if they are trapped between walls or ceilings.

Evening sightings

One of the best ways to know if bats have taken residence in your home is to watch them. You may sit outside in the evening. Bats go out to feed in the evenings, so they may leave your house once it is dusk. If you see bats coming in and leaving your home, then they most likely live there.

If you follow these guidelines and do not see any traces of more bats, then your house may be bat-free. However, you may employ professional wildlife removers to do a thorough check so as to put your mind at rest once and for all.
