Bat Removal & Exclusion in Streetsboro, OH

Bats in your Streetsboro home

Homeowners in newer Streetsboro subdivisions are often surprised to have bats at all, but the big brown bat asks very little of a house: a gap the width of a finger at a gable vent, a rake trim board or a chimney flashing, and a warm, quiet attic behind it. The fields, ponds and tree strips around the developments supply the insects; the roofline supplies the roost. Colonies here are usually found by droppings under an entry or by a single bat that takes a wrong turn into a living room.

What surprises people more is the law. Bats may only be removed by exclusion, only a licensed operator may do it for hire, and the state calendar forbids the work for much of the year. A bat job rushed in the wrong month does not remove a colony — it seals one in.

Two closed seasons, 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 the pups cannot yet fly — and from October 15 through March 31, when bats may be hibernating inside the structure. Either closed season can only be overridden with 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. A discovery in June or in the middle of winter is still worth a call: inspection, entry mapping and scheduling happen then, so exclusion begins the day the window opens.

Big brown bats hibernate in Ohio attics

The assumption that bats leave in fall is wrong for this species in this state. Big brown bats tolerate cold roosts and commonly overwinter right inside Ohio homes, tucked singly into wall voids and quiet attic corners in hibernation, making no sound and leaving no fresh sign. Sealing a Streetsboro house in January on the theory that it stands empty can entomb animals that are very much present — the precise outcome the October-to-March closure exists to prevent. A winter visit therefore starts by looking for hibernating bats, not by reaching for the sealant.

Entries on a newer Streetsboro home

Newer construction narrows the list but does not empty it. Bats enter where gable vent screening has failed at a corner, where trim has shrunk along a rake or corner board, at flashing shifted by freeze and thaw, and at the seam where a porch or garage roof meets the wall. Because these gaps are small and high, the evidence is usually on the ground: droppings gathered on a patio, walk or window ledge directly below the entry, sometimes with faint staining at the gap itself. Our crew reads that evidence to identify the active entries before any sealing is planned.

Guano, rabies and the bedroom bat

Under a roost used for seasons, guano accumulates in the attic, and dried droppings can carry the fungus associated with histoplasmosis — cleanup calls for proper protection rather than a homeowner and a vacuum. Bats are also the most frequently confirmed rabies species in Ohio. A colony in the attic is not aggressive, but a bat discovered in a room where someone was sleeping is treated as a possible exposure: do not handle it, close the room, and get guidance from your doctor or the county health department, because the animal may need to be captured for testing rather than simply released outside.

How a timed exclusion works

Within a legal window, the crew seals every gap on the home except the active entries, then fits those entries with one-way bat valves that let bats drop out at dusk to hunt over the ponds and fields and bar their return. Follow-up checks confirm the colony has fully left before the valves are removed and the last openings sealed for good. The work is a sequence of visits across days, and on a two-story home with several gables the complete sealing list is what decides whether the colony stays gone.

What not to do when you find the entry

Do not caulk the gap. In summer it traps flightless pups inside to die; in winter it traps hibernating adults; in any season, bats still indoors will work into walls and living space hunting another exit. Mothballs, sprays and ultrasonic devices do not move a colony and are not a substitute for the legal method. The working order is inspect, wait for the window if the calendar demands it, exclude one-way, verify, and seal.
