Bat Removal & Exclusion in Stow, OH

Bats in your Stow home

The bat in a Stow attic is overwhelmingly the big brown bat, and the wooded lots and older housing here suit it from both directions: insects over the creeks and lawns all summer, and quiet roof spaces to roost in — behind dormer trim, at gable vents whose screening has given out, along ridge and flashing lines where a finger-width gap is all a bat requires. Homeowners usually find the colony by its droppings, not by the bats themselves.

Big browns also change the winter assumption. Unlike a summer visitor, this species commonly hibernates inside Ohio buildings, spending the cold months tucked singly or in small groups in attic corners and wall voids. A Stow colony may therefore be resident all year, and Ohio's exclusion calendar is written to protect it at its two most vulnerable seasons.

Two closed seasons and two open windows

Ohio Administrative Code 1501:31-15-03(H)(5) bars bat exclusion from May 16 through July 31 when five or more bats are present — maternity season, when pups cannot fly — and from October 15 through March 31, when bats may be hibernating in the structure. Either closure yields only to prior written permission from the Chief of the ODNR Division of Wildlife. The open windows are April 1 to May 15 and August 1 to October 15. Calling during a closure is still useful: the entry survey, the sealing plan and the booking for the first open day all happen then.

Where bats enter a ranch or colonial

The survey follows the droppings, which gather on siding, a deck or the ground directly below an active entry. On colonials the entries cluster at dormer cheeks, gable vents and chimney flashing; on ranches, along the fascia and the long line where roof meets wall, and at attic vents with failed screens. A colony may use one main exit and several secondary gaps, and every one of them has to be found — an exclusion that misses a secondary gap is a colony that moves rooms.

Hibernation changes the winter job

A winter bat inspection in Stow looks for animals, not just holes. Big browns overwinter quietly and are easy to overlook in a broad attic, and sealing a house around hibernating bats entombs them — precisely the outcome the October-to-March closure exists to prevent. If bats are found hibernating, the plan is to wait for the April window and exclude as they become active, unless ODNR authorizes other action in writing.

Guano in the attic and a bat in the bedroom

Droppings beneath a long-used roost build up season over season, and dried guano can carry the fungus associated with histoplasmosis, so cleanup belongs to a crew with proper protection. Bats are also Ohio's most frequently confirmed rabies species. A bat discovered in a room where someone was sleeping is a health question, not just a nuisance: do not handle it, close the room, and contact your doctor or local health department — the bat may need testing rather than release.

How the timed exclusion works

Inside an open window, our crew seals every gap on the house except the active entries, then fits those with one-way bat valves. Bats drop out at dusk to feed over the creeks and yards, find the way back barred, and move on to natural roosts. Once checks confirm the attic is empty, the valves are removed and the last entries sealed permanently. The measure of the job is visits and verification, not speed.

What not to do with a colony

Do not caulk the entry gap the day you spot it. In summer that seals flightless pups inside; in winter it seals in hibernating adults; in any season, bats still inside push deeper into walls and living space. Mothballs, sprays and ultrasonic devices do not disperse a colony. The legal and effective sequence never changes: inspect, respect the window, exclude one-way, then seal.
