Bat removal can be permanent if you know what you are doing, but it is not easy task even if you are experienced. I’ve trained with an expert for two years, received my Bat Conservation International certification, but it still took many jobs before I was proficient in removing bats.

First you’ll want to find out how the bats are getting and in out of your home or building. Inspect your property to find where the bats are living, what kind of damage has been caused and what species of bat. Typically bats will fly out of their nest at dusk and then fly back home at dawn, but they won’t do it all at once, most of the time they’ll make several trips throughout the night. Typically tight and hot areas of the home or building are where bats roost, which means that the most common place to find them is in attics. Most likely you won’t find them out in the open, rather they can be found down walls, wedged into gaps between wood beams and even facia boards.
Typically, bats will leave millions upon millions of droppings (guano) all over your attic.
Bats come in all different sizes, shapes, species, behaviors and have varying birthing seasons. It is very important to understand the exact species of bat when performing a proper exclusion. Click here to learn more on how to perform a bat inspection.
If it turns out that it isn’t birthing season for the bats, a removal project can proceed. It is very important to not remove any bats during their maternity season because there will be young and flightless bats within the attic, which can result in a disaster.

Bats will usually have several holes and gaps that they use to get inside your house or building. One of the key aspects of bat removal is finding all of the areas that the bats are using. Typically the hole and gaps are very small, about a half and inch in size, and are very easy to overlook.
The best method to remove the bats is to funnel them out through their primary entry / exit point. However, there since there may be dozens of other non-primary entry/exits, you would want to seal all of those off before hand.
This way the bats that have been excluded won’t have another way in. *Important* Do not seal the primary entry / exit spot before doing this exclusion process. Click here to read more on how to seal your house against bats.
With this step, we’ll need to install one-way exclusion devices on the primary entry / exit areas that we’ve previously identified in the last step. The type of exclusion method depends on the architecture which may include: exclusion netting, funnels, screening or cones. Since ever building is different, the bats will relate to the architecture in a certain way which will require proper selection of exclusion devices. Exclusion netting or funnels are set up in such a way that the bats are able to fly out at night, but will not be able to fly back in.
This concept sounds really simple, but it is very hard to get it spot on. If not done correctly, you’ll still have a bat problem on your hands. Click here to read more about the bat exclusion process.
This step requires you to be 100% certain that all the bats are out, it is time to remove the exclusion devices and seal up the entry / exit hole. Bats do live for a long time and have a very good memory. They will make the attempt to re-enter the building or home for a while up to the next few seasons.
Bats are very fragile animals so they won’t be able to claw or chew their way back into your building, and if you did the job properly, you won’t have bats inside your building again.
The following materials work very well for sealing up the holes such as: plastic, metal screening, caulk, and high density polyurethane.
The hardest part about all of this is being meticulous and not missing one single area. Sometimes access to seal up the hole can be hard and it isn’t easy to get right the first time. Be meticulous and take your time to make sure that it is perfect.
There is a very high chance that the bats will have left millions of droppings in your attic or walls. Bat urine is also possible, but this is typically in small amounts so it shouldn’t be too big of an issue. On average there may be enough to cause the wood to rot and drywall to grow mold.
It is unlikely, but mold can cause health problems for people so it must be mentioned. I almost all cases, the bats will have left behind a very strong odor as well.
The attic, walls and any other areas that the bats have been in contact with should be thoroughly cleaned. This would typically involve vacuuming the droppings, replacing insulation and fogging the attic with enzyme cleaner. Click here to read more about cleaning up bat droppings.
Those are just the basics of bat removal, it is very important to understand that a bat removal job is not in any way a simple one. The best method to removing bats is using the live exclusion method. Most repellent products and devices have a very low success rate if any at all. If you attempt to trap or kill the bats, you’ll most likely fail or end up frustrated in the end. It is also illegal to kill bats, so don’t attempt anything other than a proper live exclusion during the non-maternity season. I understand what is necessary to do the job right and the consequences of what happens if there is failure. I cannot stress this enough that hiring a professional with a lot of experience is necessary.

PRO TIP: I often do my bat exclusion and seal up work at night! Why at night you might ask? It is easier to spot gaps and cracks at night using a headlamp or flashlight. You’d be amazed at how many holes that you find at night that you won’t catch during the day. It is best to do this project during the middle of the night, it gives us the advantage to do the job perfectly.
