Discovering bats in your attic isn’t just unsettling; it poses serious health and property risks. While bats play a vital role in our ecosystem by controlling insect populations, their presence inside your home can lead to structural damage and potential health hazards. If you’re dealing with bats (or suspect you might be), this guide will help you identify the problem, understand the risks, and take appropriate action for humane bat removal and long-term prevention.

Identifying Bats in Your Attic
Before jumping to conclusions, it’s essential to confirm that bats have made your attic their roost. Understanding their behavior and the telltale signs of an infestation can help you act more effectively.
Common Bat Species in Central Indiana
- Big Brown Bat (Eptesicus fuscus): Found year-round in Indiana, this species often chooses attics as a roosting spot.
- Little Brown Bat (Myotis lucifugus): These bats prefer warm, dark spaces and are commonly spotted in barns and homes.
- Indiana Bat (Myotis sodalis): A federally protected species, encounters with these bats require special permits for removal.
Behavior and Signs of Infestation
- Nocturnal Sounds: Hearing fluttering, chirping, or scratching noises at night could indicate bats are active in your attic.
- Droppings (Guano): Bat guano resembles small, crumbly pellets and often accumulates under roosting areas.
- Grease Stains: Oily marks around small openings or vents may indicate frequent bat entry and exit points.
- Odor: An unpleasant, musky smell is often a key sign of a bat infestation.
Recognizing these symptoms early can prevent further complications, including costly structural damage and health issues.
Health and Safety Concerns
Bats in your attic can lead to more than just sleepless nights. Here are some of the primary health risks associated with a bat infestation:
Rabies
According to the CDC, bats are a leading cause of rabies transmission in the United States. While less than 1% of bats carry the virus, any direct contact with a bat increases the risk.
Histoplasmosis
Bat droppings (guano) aren’t just unsightly; they can harbor fungal spores that cause Histoplasmosis, a respiratory disease. Research from the Indiana Department of Health shows that Histoplasmosis is prevalent in Central Indiana and often linked to bat infestations.
Property Damage
Beyond health hazards, bat droppings and urine can damage insulation, drywall, and wooden supports, leading to repair costs ranging from $1,000 to $5,000, according to the National Wildlife Federation.
Bat Removal Strategies
Once you’ve confirmed bats in your attic, removing them safely and humanely is the next step. Here are some commonly used methods:
One-Way Exclusion Devices
One-way exit devices, such as exclusion tubes or netting, allow bats to leave your attic but prevent them from re-entering. This is a humane and effective technique widely recommended by wildlife experts.
Professional Bat Removal
Hiring licensed wildlife control operators ensures compliance with Indiana Department of Natural Resources (IDNR) regulations, particularly during the maternity season (May 15–July 31) when young bats cannot yet fly.
Avoid Poisons or Traps
Traps and poisons may seem like quick fixes but are both inhumane and illegal in many areas, including Central Indiana. These methods can harm protected species and lead to further complications.
It’s crucial to work with professionals who understand the intricacies of humane bat exclusion and removal.

Preventing Bats From Returning
Once bats are removed, preventing re-entry is essential for long-term control. Here’s how you can bat-proof your attic:
1. Seal Entry Points
- Inspect your home’s exterior for small cracks, gaps, or holes.
- Use metal mesh, caulk, or other durable materials to seal any openings as small as ½ inch.
- Pay special attention to vents, chimneys, and gaps in siding or roofing.
2. Install Bat Exclusion Barriers
- Prevent bats from roosting in high-risk spaces by installing exclusion barriers around vents, eaves, and other susceptible areas.
3. Maintain Your Property
- Trim trees or branches near your home to minimize entry routes.
- Regularly inspect your attic and roof for signs of wear or damage that could allow bats access.
4. Use Bat Houses
- Consider installing bat houses away from your home to provide a suitable alternative roosting space. This helps bats relocate without disrupting their vital role in the ecosystem.
What You Need to Know as a Central Indiana Resident
If you live in Central Indiana, understanding local regulations is key to ensuring compliance:
- Protected Bat Species: Indiana bats (Myotis sodalis) are federally protected. Additional permits may be required to perform exclusion.
- Maternity Season Restrictions: Bat exclusions might not be permitted between May 15–July 31, as young bats are unable to fly during this period.
- Licensed Professionals: Always hire a licensed bat removal specialist who complies with IDNR guidelines.
By following these rules and opting for humane solutions, you can ensure both your home and the bats remain safe.
