Frequently Asked Questions

Are bats a protected species?

Bats are a protected species in Wisconsin, and killing them is illegal. Big brown and little brown bats are some of the most common species in Wisconsin, and both bats are on the threatened species list because of a disease called white-nose syndrome that has caused a significant decline in bat populations.

Advanced Wildlife and Pest Control follows all local, state, and federal regulations to ensure bats are protected throughout the removal process. All exclusion techniques cause no physical harm.

What are signs of a bat in my house?

You may have a bat problem if you hear a scratching sound at night, smell ammonia, or see stains on your siding. Bats do not chew or claw their way into a structure; instead, they gain access through structural openings. Bats look for warm, protected places to rest during the day, hibernate in the winter, and raise their young in the spring and summer.

I have bats living in my attic/home; "What Do I Do?"

Bats are commonly found roosting in buildings and do find their way into attics and walls of homes. In order to get the bats out, a bat exclusion should be completed, as bats in Wisconsin are protected, and it is illegal to kill them. Bat exclusions involve installing one-way doors that allow the bats to leave naturally but prevent re-entry into the building.

Advanced Wildlife & Pest Control performs more bat exclusions than any other wildlife and pest control company in Wisconsin. We are also the largest animal removal and pest control company in Wisconsin. We stand by all the work we perform and provide a 2-year guarantee for all our bat exclusions.

I have a bat flying around my house; "What Do I Do?"

Bats will occasionally find their way into living spaces, especially in late summer, as bats born in June learn to fly and find their way into new places. The safest course of action is to close the bat in an isolated room. If the room has windows to the outside, open them up. Place a towel under the door to prevent it from escaping the room, and then call us at 262-242-4390 to come and remove the bat. We provide 24/7 emergency services for bats flying around in living spaces. 

What should I do about a possible rabies exposure?

Anyone who is bitten or scratched by a bat must receive the rabies vaccination! DO NOT pick up a bat that is lying on the floor. Often people assume that the bat is dead, which is the most common way to get bit by a bat. Many of our customers have been bitten by a bat when trying to get rid of the bat by themselves. The rabies vaccination can cost between $1000-6000 for the four shots.


What if you are not sure?

If you wake up and find a bat in your room, the bat should be safely captured and tested. We would also strongly recommend getting the rabies vaccination just for precaution. The same precautions should be used if you find a bat in a room with an unattended child or disabled individual that can not properly communicate an interaction with a bat. 

Over 30 years, we have captured approximately ten bats that turned out positive for rabies. Under no circumstance should you release a bat that has bitten or scratched you.

Will bats go away on their own?

Not likely. The opposite will occur. The bat population will continue to grow as the female bats have their babies in late spring. Some bat colonies will leave for the winter and hibernate elsewhere. However, if a colony of bats has nested in your home, they will return to the same spot, year after year.

What are the health risks of having a bat colony in my house?

Bats are beneficial creatures outside but are problematic pests inside. When a bat colony resides in a house, it is only a matter of time before one of the bats finds its way into the living space. This poses a serious health risk because bats are considered a high-risk animal for carrying rabies.

Bats in your house will also produce piles of bat droppings in the spaces they inhabit. Bat guano is particularly hazardous due to the Histoplasma fungus found in them. Histoplasmosis is a disease that attacks the respiratory system when someone breaths in the fungus particles.

Why do I need professional bat removal?

A colony of bats living in a house presents many health hazards to you and your family. The most effective and safest way to remove bats is by utilizing bat valves along with a home exclusion. Bats are also protected in Wisconsin, and it is illegal to kill them. 

Advanced Wildlife & Pest Control performs more bat exclusions than any other wildlife and pest control company in Wisconsin. We are also the largest animal removal and pest control company in the state. We stand by all the work we perform and provide a 2-year guarantee for all our bat exclusions. 

Is the bat removal process safe?

Our bat exclusion services are completely safe for you, your family, and your pets. There are no chemicals used whatsoever. There is also no need for anyone in the house to leave while the bat exclusion job is in process. Our bat exclusions are the most effective and safest way when dealing with your bat infestation. 

How long does a bat exclusion take?

Once the building has been sealed and bat valves have been installed, it usually takes 4-8 days for all the bats to leave. In colder months, it will take longer for bats to leave due to hibernation and low activity levels. 

Why should we protect bats?

Bats are nature’s bug control. They are exceptional at getting rid of unwanted bugs around your property. They eat mosquitoes, moths, gnats, flies, and other pesky insects. A single bat can eat up to 1,000 mosquitoes in an hour! Bat guano is rich in nitrogen, which makes it an excellent fertilizer for gardens and crops. Bats are also pollinators. Over 500 species of plants rely solely on bats for pollination. Without bats, we would not have tequila, bananas, or chocolate. 

What is Wisconsin doing about white-nose syndrome?

The Wisconsin DNR has been inventorying and monitoring bat populations across the state via volunteer efforts, colony surveys, acoustic surveys, and on-the-ground fieldwork. Due to these efforts, Wisconsin has baseline information about where bat populations are, what population levels are normally found at each site, and what is considered normal bat behavior prior to White Nose Syndrome. This information helps the bat program track WNS as it spreads through the state, provides the opportunity to study the disease and possible treatment options, and helps further the understanding of the true impacts of White Nose Syndrome.
