How long will a bat live in my house?

When many people find a bat in their house, their first thoughts may be: it will eventually die if it has no access to food. This is however not true. The truth is bats can gain entry into the home and live there for months, sometimes even without the homeowner’s knowledge.  They can use secluded places in the home as their shelter and make use of small holes and cracks to get in and out of the building. Usually, bats enter the house through loose hatches and cracks or even through vents. It is very rare to see a bat flying in through the door or window.

Many bat species prefer to live in houses as opposed to the wild. This is because abandoned attics are preferable and safer than the wild. It is also a perfect spot to hibernate during the hibernation season. Bats also need safe environments to raise their young and so they choose dark and abandoned corners of the house to do this. They can live in walls, chimneys, attics, or even closets if they gain access to it. When a bat gains entrance into the home, it can survive for about 6 months without food or water depending on the climate and season. This state is a hibernation state called torpor. This normally happens during the cooler seasons such as winter.

 The bats are able to regulate their temperature, cooling it down thereby slowing down their metabolism. Moreover, the temperature in the home is optimized for living. This gives the bat an advantage over the harsh weather of the wild. If a bat gains entry into your home during the cold seasons, it may hibernate there and remain throughout the season.

In situations where the bat can gain access to exit points however, a bat can live out all of its life in your home. It only needs to go out every night, hunt for food, and then return at dawn to rest during the day. It will use the same opening to enter and exit your home and it will keep coming until the entry and exit points have been blocked. It is possible for bats to leave your house for a while and then return to it during roosting season.

Bats have been known to use the same location for roosting year in and year out, and they will remember the way even if they have been taken to other locations. This means that even if you try to catch the bat that has taken up residence at your house, releasing it into the wild alone will not guarantee that it will not return. The best thing to do after having the bat removed is to block off all access points to make sure that the bat does not gain access into your house again. Just make sure that all the work has been completed to make sure they do not come back after you have verified that all bats have indeed been removed.
