Expert Bat Removal from Attics in Oakland County
Bats in your attic? We perform safe, legal bat exclusion from attic spaces using humane methods — protecting your home and Michigan’s bat colonies. Licensed, insured, and NREPA compliant.
Bats in Attics Are More Than a Nuisance
A single bat colony in an attic can grow to hundreds of individuals. Beyond the noise and odor, bat guano accumulates rapidly and creates serious health and structural hazards.
Histoplasmosis Risk
Bat guano harbors Histoplasma capsulatum fungal spores. When disturbed, airborne spores can cause serious respiratory illness, especially in immunocompromised individuals.
Structural Damage
Urine and guano saturate insulation and wood over time, causing rot, staining, and costly structural repairs. Attic restoration becomes necessary after a long infestation.
Colony Expansion
Michigan bat colonies are most active from spring through fall. A maternity roost in your attic can include dozens to hundreds of bats — and grows larger each season if untreated.
Rabies Exposure Risk
Michigan bats can carry rabies. Any skin contact or undetected overnight exposure in a room where a bat was present may require rabies post-exposure evaluation.
Michigan Maternity Season Restriction (June 1 – August 14)
Under Michigan NREPA (Act 451), bat exclusion from attics is prohibited during maternity season to protect nursing pups. Legal exclusion resumes August 15 through April 30. We assess your situation and schedule the safest, most effective timing. Call us now to get on our schedule before the next window.
How to Tell if You Have Bats in Your Attic
Bat infestations in attics often go undetected for months. These are the most reliable indicators of bat activity in your attic space.
- Scratching or squeaking sounds from the attic, especially at dusk and dawn
- Dark greasy stains or rub marks near roofline gaps, ridge caps, or fascia boards
- Accumulation of small, elongated droppings (guano) near entry points or in the attic
- Strong ammonia odor rising from the attic, especially in warm weather
- Bats observed exiting the roofline at sunset each evening
- Dead bats found in the attic or near the home’s exterior
- Staining on attic insulation, joists, or rafters from urine saturation
- Bats flying indoors through gaps in the ceiling below the attic

📞 Call for Free InspectionHow We Remove Bats from Attics
Our bat removal from attics process follows a proven six-step protocol — compliant with Michigan NREPA, humane, and permanently effective. No poisons, no traps, no shortcuts.
Attic Inspection
We enter the attic and perform a full assessment — colony size, entry points, guano volume, insulation condition, and structural impact.
Entry Point Mapping
We identify every gap, crack, and opening bats use to enter. Common attic entry points include ridge vents, soffit gaps, fascia separations, and gable vents.
Exclusion Device Installation
One-way exclusion tubes or nets are installed at all active entry points. Bats can exit but cannot re-enter — no bats are harmed.
Secondary Points Sealed
All non-primary entry points are permanently sealed with caulk, hardware cloth, foam backer rod, and flashing while exclusion devices remain active.
Final Seal & Removal
After 3–7 days (or longer per NREPA timing requirements), exclusion devices are removed and primary entry points are permanently sealed.
Attic Cleanup & Remediation
We remove contaminated insulation, decontaminate surfaces, and restore the attic — eliminating odor, health risk, and the scent trails that attract new colonies.

Common Bats Found in Michigan Attics
Knowing which species is in your attic matters — it affects colony size, behavior, and the timing of safe exclusion. Our technicians identify species during the initial inspection.
Little Brown Bat Myotis lucifugus
The most common attic-roosting bat in Michigan. Maternity colonies of 50–300+ females congregate in warm attic spaces each summer. They enter through gaps as small as ⅜ inch.
Big Brown Bat Eptesicus fuscus
Larger and hardier, Big Brown Bats often overwinter in attics rather than migrating. A year-round presence means guano accumulation continues through winter. They enter through gaps as small as ½ inch.
Tri-colored Bat Perimyotis subflavus
Less common in attics but occasionally found roosting in tight spaces near soffits and fascia. Smaller colonies. Listed as a threatened species — extra care required during exclusion.
