It can be easier to get bats out of a chimney than in other parts of the house.
The method is the same, which involves installing a one-way exclusion device that lets the bats fly out but not back inside. But how does one do that?
In this guide on how to get bats out of your chimney, I’ll tell you how to get rid of them. So, without further ado, let’s dive in!
If you’ve recently found out that you have a bat infestation in the chimney, the first thing to do is not panic!
You can let bats out of the chimney either from the top or through the bottom. Let’s take a look a the steps involved in ejecting bats out of a chimney:
Step 1: Figure Out How They Got Inside
Since bats are small, they need no more than 3/8th of an inch to wriggle their way inside. But, unlike other pests and rodents, they don’t chew on walls to make more wiggle room, which is a relief. This prevents costly repairs later on.
Here are some of the common areas targeted by bats for use as entry points:
- Around vents where pipes run inside and outside the building
- Corners and meeting points of walls and roofs
- Any cracked window panes, window screens, or busted windows
- The siding of the roof and its upper areas
- Missing or broken bricks
- Siding holes
Once you identify the entry point, fix it so that bats can’t enter through it again.
Step 2: Eject The Bats
As I mentioned earlier, using one-way exclusion devices is the only effective method to get rid of bats for good.
I don’t recommend lighting a fire inside the chimney if you were wondering whether the fumes would drive them away. Not all bats will be able to escape in time, and some of them will either suffocate from the smoke or burn to death, both of which are inhumane.
In addition to that, relying on repellants is not the best idea since sounds and lights don’t work on bats. However, using them in conjunction with exclusion devices might help your cause.
Another method I advise against using is fumigants and poison. It is illegal to do so in most places and inhumane. Moreover, there aren’t any legally registered products that I can recommend for the same.
Using traps won’t be efficient either since bat colonies can run into hundreds, and traps won’t get them all out. They also reproduce fast, and before you know it, you’ll have a whole clan living in the chimney.
Step 3: Sealing The Building
Seal the chimney properly to avoid them from moving to other parts of your house. Use wire wool, expanding foam, or hardware cloth as a sealant, and after that, install the exclusion device.
If you’ve managed to evict the bats successfully, remember to clean up any biological matter they might have left behind since that can attract other bats, maggots, rats, etc. Plus, it can cause severe disease and, not to mention, stink up the place.
But if the infestation seems too severe, it’s best to call a trained professional.
