How to get rid of bats and save your sanity Try a bat removal device or repellent. A bat excluder works very well if you know where bats enter. When in doubt, call a professional. To remove them, identify their entry and exit points, making sure not to seal them while the bats are inside.
Killing them is both inhumane and will create an uninhabitable environment due to the smell of a colony of decaying bats. To gradually exclude bats from your home, start by closing every entry point you've found, except for what appears to be the main entrance. If all the alternative entry points have been closed and the one-way door works, all bats should be out in three or four nights. Ecolocation can direct bats directly to their favorite entry points, so you'll want to place a bat house as close as possible to the old “bat door” as a powerful deterrent.
There are a lot of creatures you don't want to have in your home: termites, snakes, rats and bats, for example. It is imperative to seal off all possible entrances to keep bats away, as bats prefer to return to the same shelters year after year. They can also examine the outside of the house for small brown stripes and small black balls, evidence of bat urine, and guano. The smoke will come out of the attic showing you the holes, and the bats will come out through the holes where the smoke comes out because they assume that the house is on fire and cannot breathe in the attic.
The first thing you should know about how to get rid of bats is that they cannot be eliminated with poison. When your bat problems are over, you'll need to restore areas damaged by bats or the removal process. Aerosols, animal urine, noise generators, and lights sometimes work as temporary deterrents, but there are no easy solutions when it comes to eliminating bats. Neutralizing odor is not only desirable, but essential because the scent attracts bats back to the chicken coop.
If kept at an appropriate distance, bats can be excellent neighbors, the kind that emerge from their sleep every night to act as a natural mosquito repellent, even. The bats will return as they follow the smell of faeces and urine, so it will need to be cleaned and the hole sealed. Because pesticides and the killing of bats are illegal, pest control companies use a process called exclusion.
