Found a Bat in Your House? Here’s Exactly What to Do

Finding a bat in your home is unsettling. We get it. One minute you’re relaxing in your living room, and the next, something is swooping around the ceiling fan. Take a breath. The bat is almost certainly more scared than you are, and bats are not aggressive by nature. Do not chase it, swat at it, or try to grab it. You are not alone either, because this happens more often than you might think, especially here in Central Indiana.

The good news is that there are clear, practical steps you can take to handle it safely. After years of helping homeowners across Marion, Hamilton, Boone, and Hendricks counties work through this exact scenario, we put together a walkthrough of everything you need to know.

How Do You Safely Isolate a Bat in Your Home?

If the bat is still flying around, close off the room it’s in. Shut doors to other parts of the house to keep it contained. This makes removal much easier and prevents it from tucking itself somewhere harder to find, like inside a wall, behind a curtain rod, or under furniture.

If you can open a window or exterior door in that room, the bat may find its own way out, especially after dusk when they naturally want to be outside hunting insects.

Do Not Touch It With Your Bare Hands

According to the CDC, bats are the most reported rabid animal in the United States. A bat bite can be so small and painless that it leaves no visible mark, which is why exposure is easy to miss. Never pick up a bat barehanded, even if it looks injured. Thick leather gloves are the minimum, and honestly, the safest move is to leave removal to a professional.

If the bat has landed and stopped moving, you can carefully place a container (a coffee can, plastic storage bin, or shoebox all work) over it and slide a piece of stiff cardboard underneath to trap it. Keep it contained. Do not release it. Do not kill it by crushing the head, because the brain tissue is what the lab examines for rabies.

This is where we can help. The LadyBug offers rabies testing coordination for our customers. If you suspect any exposure, we will take the contained bat directly to the local health department’s lab for testing, so you do not have to transport a live or captured animal yourself. You get peace of mind faster, and if a test comes back positive, your family and your doctor have the information needed to start treatment without delay.

When Should You Call a Doctor After Finding a Bat in Your House?

If you are wondering whether you need to be on the phone with someone right now, this list takes the guesswork out. Read through the situations below, and if any of them apply to you or someone in your home, contact your doctor or the county health department right away.

• You woke up, and there was a bat in the room. Even if you do not remember any contact, assume you could have been bitten while asleep. This is true for any adult, not just for children.
• A child was in the room with the bat. Kids often cannot tell you reliably whether they were bitten, scratched, or touched by an animal. The CDC and the Indiana Department of Health both recommend treating this as a possible exposure.
• Someone was bitten, scratched, or had direct skin contact. Even a tiny scratch counts. Wash the area with soap and running water for at least fifteen minutes, then call your doctor or the county health department.
• A pet interacted with the bat. Call your veterinarian, especially if your pet’s rabies vaccination is not current.

In any of these situations, do not release the bat. The contained bat is the fastest way to get a clear answer.

Call The LadyBug for Removal and Inspection

Once you are safe, it is time to figure out how the bat got in. A single bat usually means one of two things: a one-off that slipped in through an open door, or a colony roosting in your attic that sent out a scout. Multiple bats, or bats that appear repeatedly, almost always mean a colony.

When you call us, a technician comes out, safely captures the bat, and releases it outside your home as required by Indiana law. Then we do a full exterior inspection to find any opening a quarter inch or larger. That is roughly the size of a pencil, which is all a bat needs to get in. Our team is NWCOA Bat Certified, and you get a detailed quote with photos of every entry point we find.

How Does Bat Exclusion Work?

Once entry points are identified, we will permanently seal them and install a one-way eviction device on the main access point. The device lets bats fly out of the attic but physically blocks them from coming back in. We leave it in place for seven to ten days so the entire colony has time to leave on their own schedule. Then we come back, remove the device, and seal the final opening.

Attention to detail is what makes exclusion actually work. Miss one pencil-sized gap and the bats find their way back in.

Is Bat Guano Dangerous?

Yes, it can be. Bat guano can carry Histoplasma capsulatum, the fungus that causes histoplasmosis, a respiratory illness you can pick up from inhaling spores when dried droppings get disturbed. This is why you should never try to sweep, vacuum, or dry-brush guano on your own. All three methods kick spores into the air.

Here is the part most homeowners do not expect: bat guano looks different from other animal droppings because bats eat almost nothing but insects. Their droppings are made up mostly of insect fragments and shells, which is actually a useful identification tip. Mouse droppings crumble into fine dust when you press on them, and bat guano crumbles into shiny, sparkly insect bits. Guano also builds up fast when a colony has been roosting for a while, sometimes many pounds per season, depending on colony size.

Attic remediation is one of the services we offer once the colony is out. We remove any contaminated insulation, sanitize the space to neutralize remaining spores, and blow in fresh insulation so your home is restored properly and safely.

What If You Cannot find the Bat?

If the bat disappeared somewhere in your home and you cannot locate it, call your local health department for guidance. In Marion County, that is the Marion County Public Health Department. Hamilton, Boone, Hendricks, and surrounding counties each have their own health offices that can walk you through the next steps.

When a bat cannot be found and tested, health authorities generally recommend post-exposure rabies treatment anytime there is a realistic chance of exposure, especially with small children or someone who was sleeping in the room. Do not wait on this. Early treatment is highly effective. And call us too. A missing bat usually means it tucked itself into a wall, behind a curtain, or inside the attic, and we know where to look.

Are Bats Protected in Indiana?

Yes. Most Indiana bat species are protected under state law, and timing matters. According to the Indiana Department of Natural Resources, bat removal is not advised from June 1 through August 15, because this is maternity season and the pups are not yet old enough to live on their own. During those months, the work to do is the prep work. A full inspection, a documented entry-point map, and a plan for exclusion once the season ends in the fall. That is one more reason to work with a licensed wildlife professional who knows Indiana’s regulations inside and out.

Indiana is also home to several bat species, but the two we see inside homes most often are the Little Brown Bat and the Big Brown Bat. Both are valuable pieces of our local ecosystem. A single bat can eat thousands of mosquitoes in one night, which is great news if you like sitting on your patio in July. Their place, though, is outside, not in your attic.

Let The LadyBug Handle It

We’ve been evicting freeloading bats from Central Indiana homes for years, and we’ve seen just about every scenario you can imagine. One of the wildest spots we work in is the Stonegate Neighborhood in Zionsville, where nearly every home on the block has dealt with a bat colony at some point. We’ve helped a lot of those residents reclaim their attics, and we can help you, too.

Whether it’s a single bat that flew in through an open door or a full attic colony that’s been there for seasons, our NWCOA Bat Certified team knows exactly what to do. Bat problems don’t fix themselves. The longer a colony is left alone, the more guano builds up and the more damage it does to your insulation and air quality.

Contact us today for an inspection, or call us directly at 317-601-2873. We proudly serve homeowners across Central Indiana, including Indianapolis, Carmel, Zionsville, Fishers, Noblesville, Westfield, Brownsburg, and surrounding communities.
