Bat Problems: The Dangers of Having a Bat Infestation

Whether you have one bat or an entire colony in your home, you’ll want to remove the bats quickly. Not only will a bat infestation make you uneasy, but there are two main health risks involved:

  • Rabies. People or animals that have been bitten by a bat should be treated by a physician or veterinarian. If possible, the bat in question should be collected and tested. Don’t ever handle bats, even if they appear healthy.

  • Histoplasmosis. This is an infection that occurs from breathing in fungal spores found in bat guano (bat droppings). When bats congregate unchecked in your attic, in your basement, or inside of your walls, they can produce large amounts of unhealthy waste. This is why having a professional perform removal and clean up is crucial.

If you’re wondering when to remove bats from your home, the answer is right away. The dangers above are just a few reasons you shouldn’t let a bat infestation go on too long. Unsure how to keep bats out of your house or your business? Keep reading or get in touch with Varment Guard!

We Specialize in Removing Bats Humanely and Quickly

Bas are valuable contributors to the ecosystem and control insect populations. Bats eat flying insects like mosquitoes, for example. A bat colony may even eat thousands of insects in a single evening in preparation for their winter hibernation... but that doesn't mean you want them in your house!

Because bats are important to the ecosystem, Varment Guard focuses on efficient and humane removal of bats. Our goal is keeping bats outside so they can do their job (and you get peace of mind). Varment Guard offers:

  • Bat Trapping & Removal
  • Bat Prevention & Exclusion
  • Entry Problems & Damage Repair

Clean-Out & Restoration Services After a Bat Infestation

We specialize in complete attic clean-out and restoration as well as partial clean outs after a bat infestation.

  • Attic restoration starts with removal of all bat guano (bat droppings) and damaged insulation
  • We then disinfect and deodorize to kill bacteria, fungus, parasites, and odor left behind from bat colonies
  • We finish by installing new cellulose insulation to meet or exceed state-required insulation values

In some situations, complete insulation removal may not be needed and in those cases we can provide partial clean-out along with disinfecting, deodorizing, and fresh cap of the new cellulose insulation.

Attic Clean Out Before And After

How Bats Enter Your Property

Many customers who have experienced a live bat think that it came down the chimney. However, our certified bat specialists rarely find that a bat in the living space has entered through the chimney.

Bats almost always enter through the attic and then get into the living space through a crack, gap, or hole on the interior of the home.

Once a bat is in the living space, it may gravitate to the fireplace because it can feel a draft of air coming from the chimney. Bats can get inside through cracks as small as ⅜ of an inch wide. Removal of bats is done by a process of excluding the structure of all potential bat entries and placing a one-way door directly over the main entry point. This allows the bats to humanely exit the structure at night. Once the bats have gone out the one-way door unharmed, they are able to find a new roosting area preferably out of human contact.

We Are Experts a Removing Bats Safely

Most bat populations are declining throughout the US; all bats are protected and cannot be intentionally harmed. Intentionally harming bats in your attic is illegal but removal from your attic is not. For your safety and the bat’s safety, bats should only be handled by a wildlife professional.

How Varment Guard Can Help During Bat's Birthing Season

During the birthing season, bats cannot be excluded from a structure as the flightless young would not survive without parental care. Some states (like Ohio, for example) allow exclusion with a state-issued permit, but other states do not allow removal during the birthing season at all.

Varment Guard’s bat specialists can still help during the birthing season, however. We can inspect the structure and develop the eviction plan. We can also start by doing some of the exclusion work, as long as it will not prevent the bats from exiting or returning.

Once this season is over, we can quickly exclude the last areas and hang the one-way door. One-way doors typically hang for 7-10 days to allow plenty of time for all the bats to exit.

How Do Bats Get in My House?

Bats enter homes through damaged roofs and siding, vents, chimneys, open windows, and any gaps in the framing. So, it is crucial to keep up with household maintenance and patch any areas where bats could enter. Learn more about how bats enter your home!

How Do I Keep Bats Out of my Home?

To keep bats out, the first step is to remove any bats that are currently in your home with the help of a pest control professional. Then, checking the roof, controlling vents/chimney, and sealing any openings will better ensure that no creature can enter. Learn more!

What Should I Do About Bats This Winter?

Bats begin hibernating in mid-October and stay dormant until they wake up in spring. In order to hibernate safely, bats need to find roosts where they can stay warm and sheltered. They also seek out dark, secluded, and sheltered places that can keep them safe from predators. Learn more about bat hibernation!

When Do Bats Mate?

Unlike many mammals, bats don’t mate in spring. Instead, they actually mate in fall, shortly before they enter hibernation. Female bat eggs become fertilized months after initial mating, after hibernation ends in early spring. Furthermore, bats eat during the spring to make up for lost energy during hibernation.

Does One Bat in the House Mean More Are Inside?

No, not always. But there’s always a chance there may be more living in your attic. If you see multiple bats in your house, then that’s a sign of an infestation. To get peace of mind and make sure your space is bat-free, call Varment Guard. One of our expert technicians will come to your home and inspect your space!
