Discovering a single bat indoors might seem like a one-off event, but finding multiple bats in your home or commercial building is a clear sign of a much larger problem. Bats are social creatures and often roost in colonies—especially in quiet, enclosed spaces like attics, wall voids, or drop ceilings. Whether you’re a homeowner or a business owner in Chicago, ignoring this issue can lead to structural damage, serious health risks, and repeated bat invasions.
In this blog, we’ll explain why multiple bats might be inside your property, the dangers they pose, and the safest, most effective way to remove them.
Why Bats Choose Chicago Homes and Businesses
Chicago’s older buildings, abundant trees, and proximity to Lake Michigan create ideal bat habitat conditions. Cracks in siding, gaps in soffits, open chimneys, or broken vents often serve as easy entry points—especially in structures not properly maintained.
For a deeper understanding of why bats target urban structures, visit our post on why Chicago homes attract bats and how to spot an infestation.
Common Areas Bats Roost Indoors
Bats usually hide in areas you rarely visit, such as:
- Attics
- Wall cavities
- Behind shutters
- Rooflines and soffits
- Basements with exposed beams
If you’re noticing guano buildup, strange noises at night, or even visible bat sightings indoors or around dusk, it’s time to take action.
Risks of Hosting a Bat Colony Indoors
While bats play an important role in the ecosystem, their presence indoors is dangerous. Here’s why:
- Health Risks: Bat droppings (guano) can carry Histoplasmosis, a lung infection caused by fungal spores. Additionally, bats are potential rabies carriers.
- Structural Damage: Guano buildup can rot wood, stain walls and ceilings, and destroy insulation.
- Noise and Odor: A bat colony emits high-pitched squeaks, fluttering wings, and a strong ammonia-like odor.
If you’re unsure of the scope of the problem, we recommend scheduling an expert home inspection and bat removal in Chicago right away.
What to Do If You Have Multiple Bats Indoors
- Don’t Touch Them
Bats should never be handled without proper training and equipment. Even dead bats can carry pathogens. - Close Off the Room
If a bat is flying in a living or working area, isolate it by shutting the door and opening a window to allow it a safe exit. - Call a Professional Bat Removal Service
Bat colonies require a structured removal and exclusion plan. Humane removal methods are critical, especially during pup season when young bats cannot fly.
Our Chicago bat removal experts use safe, eco-friendly exclusion techniques to remove bats without harming them—and prevent re-entry.
Ongoing Prevention & Animal Proofing
Once bats are gone, preventing a future invasion is key. We recommend full animal proofing and home repairs that include:
- Sealing all exterior gaps
- Installing chimney caps and vent covers
- Replacing torn screens
- Inspecting soffits, fascia boards, and rooflines
For commercial buildings, we also offer wild animal removal and exclusion solutions tailored to offices, restaurants, warehouses, and more.
