How Long Does Bat Removal Take?


Bat Removal Services

How long does bat removal take? As much as we would like it to be a one-day process, the length of time it takes for bat removal from a house, office building, church, or other structure can vary greatly. Bats are stubborn! Once they move into a structure, they will not leave until they are kicked out. If only getting rid of bats was as easy as them moving in.

There are a few significant factors that can affect how long it takes to remove bats from the structure. For example, the size of the structure, the size of the bat colony, where the bats are roosting in the structure, when they last got food and water, baby bats, and the weather all can affect how long bat removal takes. Removing bats from buildings can be done, but it is not an overnight magic cure. Our method works, but only as fast as the bats allow it.

Where are the Bats?

We service all properties from residential homes to commercial properties, so we have seen every type of infestation from massive to minimal. Bat removal can take longer depending on the kind of structure that the bats have moved in to. Structure size can affect the length of time for bat removal because the bats can travel throughout the walls of the structure and often end up in the basement or lower levels. Bats use wall cavities as highways systems to move throughout the structure. It takes time for the bat to crawl its way back up to the attic area where it originally entered.

Bats will need to return to the attic area to find their exit out of the structure to feed. The bats will leave through the exit which will have an exclusion device installed to make sure the bats cannot enter back into the house. The bats fly out at night in search of water and to feed on insects. If there is a large number of bats in the colony, they will need time to complete their feeding cycle. Bats that have just returned from a meal won’t have to leave the roost for a few days. Location of the bats in the structure and the bats feeding cycle both affect how long bat removal takes.

Baby Bats?

The presence of baby bats can also affect how long bat removal takes. During the summer, female bats will give birth to one or two babies, also called pups. Those pups will be dependent on the mother bat for at least six weeks. That means that baby bats will not be leaving the roost for at least six weeks after they are born. The baby bats depend on the mother and her milk. If the mother bat leaves the roost and is unable to return, the baby bats will die. Because the baby bats need the mother to survive, you should avoid bat exclusions during the birthing season.

You cannot do bat exclusions if baby bats are present in the home—however, in some states because of health-related issues from the bats, the state may grant exclusions during the birthing season. You will need to check with your state’s wildlife conservation group. If baby bats are found in the structure, the bat removal process will take a more extended amount of time. Because the bats are federally protected, the national resume date for bat removal is August 15. By then, all the baby bats should be flying and feeding independently, and exclusion can resume.

Bats in Winter vs. Bats in Spring/Summer

How long bat removal takes during the warmer seasons is different than how long bat removal takes in winter. Bat removal is seasonal work because of how the bats react during the seasons. As the temperatures cool and fall weather sets in, the bats will search for a hibernating roost. Bats hibernate in structures during the winter months. Bats that hibernate primarily sleep through the winter.

However, the bats can wake up due to fluctuating weather conditions. If the bats get too cold in the area they are hibernating in; they will wake up and search for a warmer area in the house to go back to resting. Bats will not leave the structure until Spring—when the temperatures are warm enough. While we can get the home prepared for the bats to leave, there is nothing that can be done to get the bats to move in the winter. That is why bat removal takes longer in the fall or winter.

In the Spring, the bats wake up and immediately search for water. Which means when the temperatures are warm enough, the bats will willingly leave the structure, and at that point will be removed from the home—through the exclusion devices. Have you ever looked up at the night sky in the summer and seen bats flying around? That’s because June, July, and August are the months the bats are very active. There’s an abundance of mosquitoes out for them to eat! That is usually everyone’s favorite thing about bats!

It is crucial to keep in mind the birthing season during the summer months. Exclusions are prohibited when babies are present in the summertime. Bats are resilient, and these little creatures can become active as early as March if the weather cooperates!

Rushing Bat Removal

There is no way to make bat removal go any faster than the bats allow. Rushing the bat removal process can result in some nasty consequences. When a homeowner gets impatient and seals the bat entry points shut without providing an exit, the bats get trapped in the house. If the bats are lost in the walls and searching for a new exit, they may die in the wall. Trying to do bat removal during the birthing season, can leave you with dead baby bats. Having dead bats inside the walls of your home is not healthy and will stink in time. Killing bats is illegal. Bat removal must be done safely because bats are federally protected. The best way to get rid of bats is by calling professional bat removal experts.


Getting rid of bats is a process. There is no way to tell how long bat removal will take. Overall, the bats decide how fast the process will work. The type of bat removal method we use, while it is the most effective and permanent solution, still takes time to resolve the issue. We cannot give an exact date when the bats will be out of your house. The bats leave, but it does take some time. At some point, each bat will need to go out to feed or get a drink. During the bats most active season, most bat removal companies ask for 30 days to allow the bats to leave. Any issues after that, the company’s warranty should have you covered!
