How to Get Rid of Bats in an Attic
There are several ways to get rid of bats in an attic. If there are just a few bats, and it appears that there is no colony present or if there is a solitary bat in the attic, they can be physically removed by a trained professional who has proper protective equipment.
There are several different approaches to remedying a bat infestation in an attic. However, it is important to note that many states have laws or regulations that address bat control and which provide specific requirements and protections for these animals. It is important to avoid using any home remedies to control bats, including those which involve mixing chemicals.
If you encounter such a problem, it is highly recommended that you contact a pest control professional who is trained in bat removal.
If there is a bat colony in the attic, it is best to exclude the bats from returning. Some social bats develop maternity colonies, or colonies of females gathered to have their young. The young are dependent on their mothers for some time. No colony should be excluded from return until the young are capable of flying. Prior to this, the adults return each morning and feed the young. Restricting access of the females to the young will prevent feeding of the young and they will die. Check the local bat species to determine when it is safe to exclude the colony. Usually state universities will have sections of their websites dedicated to locally found bats and when the young are reared.
When exclusion work is to be done, observing the structure at dusk will give an indication as to the entry and exit points. After the bats have left, the holes can be sealed. Check inside during the day and look for daylight after sealing. Also check for air currents which may disclose other access points.
One-way tubes, cones or other devices can be installed when the entry point is found. These devices can be placed over the entry and when the bats emerge, they cannot return back to the colony. These are very effective. Some people prefer to place bat houses nearby but the likelihood of the displaced bats roosting there is limited.
After the bats are removed, it is best to clean up any guano or urine to prevent spread of disease. Always use personal protection when cleaning up guano or urine.
