How much does bat removal cost?
It depends on the house and the guano. In Peoria, Illinois, widely published ranges start near $300 for simple exclusion and climb past $5,000 when years of droppings have soaked the insulation. Ask for itemized pricing that separates exclusion, sealing, and cleanup.
Why is sealing the most expensive part?
Because it is the most labor. bats fit through three-eighths of an inch, so every ridge vent, fascia joint, gable louver, and chimney gap on a Peoria house gets screened or sealed by hand, often from a ladder or lift. A simple ranch takes hours. A two-story house with old soffits takes days.
Is a cheaper quote a bad sign?
Sometimes. A very low bat quote in Peoria usually leaves out secondary sealing, the follow-up dusk check, or the cleanup, and each of those comes back as a separate bill later. Ask what is not included. Also ask whether the Peoria provider is licensed for wildlife work in Illinois and knows the maternity dates.
What should a bat removal quote include?
Look for these items on a Peoria quote: inspection findings, device count, sealing scope, cleanup and insulation pricing, timing relative to the state's maternity rules, and a warranty on reopened gaps. It should say what happens if bats return. Vague quotes usually mean missed gaps later.
Is bat guano dangerous?
The danger is in the dust. Fresh droppings on a Peoria deck are not much of a hazard, but a long-established roost leaves dried guano that can carry histoplasmosis spores when swept or vacuumed. A Peoria cleanup crew wets the material, bags it, and wears respiratory protection. Do not go up there yourself.
How do I know it is bats and not mice?
The droppings tell you. Bat guano is dark, slightly shiny, breaks into insect parts under a fingertip, and piles up under the roost in a Peoria attic. Mice leave droppings along walls and in cabinets. If you hear chirping in the walls at dusk in Peoria, that is bats, not mice.
Will bats come back after exclusion?
Only if a gap was missed or reopens. The colony returns to the Peoria neighborhood, circles the roofline, and finds any opening left behind. That is why a Peoria provider should seal secondary gaps, screen vents, and cap the chimney, not just cover the main entry. a bat house nearby gives them somewhere else to go.
Do most people want bats removed from their neighborhood?
Not according to one recent survey. Before comparing Peoria quotes, note this: homeowners who tolerate bats are not unusual: in Puri and colleagues' 2022 survey of 1,006 metro-area residents in the southeastern United States (published 2024), 42.6% of people with bats nearby wanted the population unchanged, which speaks to neighborhood attitudes, not bats in attics. If you are in Peoria, use this as a starting point for questions rather than a prediction for your home.
