What Equipment is Needed for Bat Exclusion?
Bats are brilliant at keeping insect numbers down, capable of eating up to a thousand mosquitoes in an hour. However, due to the diseases and parasites that they carry, they aren’t very popular as housemates. If you have bats in the attic, then exclusion is your best means of control.
If you want to do the exclusion yourself, you’ll need some basic equipment. You’ll need a ladder to be able to access high points on the exterior of your house, as well as the tools and materials to make the necessary repairs.
Bat exclusion is a fairly simple process. First, identify where the access points are and then seal all but one. The last entry point needs to be the main one, and instead of sealing it, install the exclusion door. An exclusion door is a piece of steel mesh or other material fastened in such a way that allows the bats to leave the building but prevents them from getting back in.
It’s the best means of bat control because it forces the bats to find a new home without you coming directly into contact with them.
Equipment needed for bat exclusion
The first piece of equipment that you’ll need is a ladder. To find all the potential access points that bats can use, you’ll need to be able to get up and inspect the soffits, eaves, and roof. It would be best if you did this before heading to the department or hardware store to get the rest of the equipment so that you know which materials you need.
For example, bats can fit through tiny crevices (anything the size of a dime or larger), which you can seal with silicone caulking. Larger openings, however, will need to be covered by materials such as hardware cloth, or steel mesh, or metal flashing.
Once you know the size of the gaps, you’ll have a better idea of the specific equipment you need to do the job. You won’t need every item on this list as long as you have the right materials and tools to repair the holes, and either the equipment to make the exclusion door or a pre-built exclusion device.
- Silicone caulking
- Caulking gun (or buy the caulking in a tube that makes for easy application)
- Hardware cloth, steel mesh or metal flashing
- Drill and screws
- Bat exclusion device, or bat netting
How to exclude bats from your home
To successfully exclude your bats, follow these steps.
- Observe the bats exiting at dusk. You’ll be able to see where their main access points are and where you will need to install the exclusion door.
- Seal all the previously identified openings, except the main entrance.
3. Install either a pre-built bat exclusion device (such as an exclusion cone) or bat netting. If installing netting, attach it to the wall along the top and side of the net, leaving an area loose at the bottom for the bats to crawl out.
4. Leave the exclusion device in place for at least seven days to be sure that all the bats have left before sealing that as well.
