Instructions on How to Remove Bats In a Attic
Visual Inspection: A visual inspection is needed to determine how the bats are getting in and out of the structure. They will usually fly out at dusk or right at dark. Sounds of high pitched chirping or squeaking can be heard giving away their roosting areas before they drop out. Once in a attic, bats will often not be found in the open, but will be tucked away in a confined area of the soffit, wall, or a vent. Often, guano or bat droppings will be present under the roosting area. You will need to pay special attention to species of bat, as some are state and federally protected, and to the time of year, as some areas forbid disturbing bats during maternity season.
Pre-Sealing The Outside Of The Home: For proper exclusion to be successful, before bats are excluded, all secondary entry points must be sealed. This would include all openings that are 3/8″ and larger around the top half of the home. You’ll want to leave the primary opening the bats are using alone. All secondary openings must be correctly closed to prevent excluded bats finding a way to gain re-entry. This is often easier said than done, unless you have a “wildlife eye”.
Installing Bat Excluders: Install the excluders over the primary opening of the home. Excluders can be cones, netting, funnels, or other material, that safely allow the bats to fly out, but will not allow them to fly back in. Determining the excluder to use will greatly vary on the location of the primary opening. Normal architecture will only allow some excluders to be conducive, where other devices it may not. This is often the biggest challenge with a bat job, as a improperly hung excluder can allow bats re-entry. Bats will not come out of a primary opening every night, so it is important to understand that bat excluders to remain in place a minimum of 4 – 5 days, or until all the bats are out.
Sealing The Primary Opening: Once you are 100% positive all the bats are out of the attic, you can take down the bat excluder. Now, it is time to seal the primary opening. This is the most important opening to seal, and will require experts skills to ensure there is no gaps left. Because bats are excluded, they will try to gain re-entry, so you must ensure everything is tight and secure. Bats have excellent homing abilities and will return to that opening over time. Bats do not chew to gain re-entry, but will land on the structure, crawl around, and search for a small gap to enter. So it is very important to ensure there is no openings left unsecured, or they will get back in.
Guano Removal and Disinfecting: Bats, even though very small in size, have one of the quickest accumulating droppings of any mammal. Because a single bat can consume up to 500 mosquitos in a night, they can match that with droppings. If you have had a large colony of bats, the droppings can accumulate. Disinfecting and sanitizing services for bat jobs are needed when there is odor from the guano accumulation, there is urine staining, to remove attractants as bats have excellent homing abilities, and to thoroughly clean and disinfect the attic. That can include insulation removal and replacement and other restoration services performed by Animal Pros. This is a important step, as bats will continually be attracted to a roosting area that sells like bats. Contact a Animal Prosspecialist for an evaluation today.

Why are Bats Attracted To a Attic?
Bats will commonly be attracted to man-made architectural buildings and homes, as they create a perfect roosting area, rather than a tree, outside. Structures offer protection from predators and the elements, much like a cave, while providing a suitable spot during the day to roost. Bats will also utilize structures as a nursery during maternity season mid April – August. The most common bats to utilize structures include the Big Brown Bat, Little Brown Bat, and the Mexican Free-tail Bat. Bats are capable of surviving in a structure, as a attic provides a stable high temperature year round. Soffit voids, roofline gaps, and open vents provide excellent crevices that bats can enter.
