Columbus wildlife guides What's in the attic, how it got in, and what Ohio rules say
Each guide explains one animal, one gap, or one kind of attic mess, with the Ohio details called out below. When you want someone to look at the house, the Columbus team is a form away.
Animals
Bats in the attic
Ohio restricts exterior bat exclusion from May 16 through July 31 when five or more bats are present, and from October 15 through March 31 if any bats are present. The better windows are April 1 through May 15 and August 1 through October 15. Around Columbus we inspect during a restricted period and still do not seal flightless or hibernating bats inside. Gaps from the attic into living space can be closed anytime. The state page is the Ohio DNR guide to bats in buildings.
Read the guideRaccoons in the attic
Along the Scioto, the Olentangy, and Big Walnut, raccoons treat a loose soffit like a front door. The same is true anywhere a tree leans onto a Columbus roof. Ohio says a captured raccoon is released on the property or euthanized, not relocated. We follow that, and we do not seal a mother out and leave kits in the wall.
Read the guideSquirrels in the attic
Clintonville, Upper Arlington, and the older streets in Dublin and Worthington see this every fall, when squirrels settle in, and again in late winter when young show up. Gray squirrels and fox squirrels are both common, and southern flying squirrels work after dark. A nest with young means the hole stays open until they can leave. The repair is metal.
Read the guideSnakes in the house
Around Columbus, a snake in an attic is usually a gray ratsnake. They are nonvenomous climbers, and they go where the mice are. Ohio has three venomous species, the copperhead, the eastern massasauga, and the timber rattlesnake, and they are rare or absent in Franklin County houses. Still, do not pick one up to check.
Read the guideOpossums around the home
Around Columbus they show up under porches, in sheds, and in a garage that was left open, from older houses near German Village to newer decks in Powell. Ohio says a captured opossum is released on site or euthanized. We confirm the space is empty, including young, before any boards go up.
Read the guideSkunks under the house
In the Columbus area, skunks show up under sheds and porches, especially where a yard meets a field in Hilliard, Pickerington, or Delaware County. Spring dens may have young. Ohio says a captured skunk is released on the property or euthanized. A bite or a pet contact is a doctor and a vet question, and it should not wait.
Read the guideGroundhogs under structures
Columbus-area yards that back up to a field, a ditch, or a weedy fence see groundhogs every summer. Pickerington and the edges of Delaware County hear this call a lot. We do not fill an active burrow, and we do not gas a den that may connect to a crawl space.
Read the guideMice and rats
In Columbus houses, mice are often the reason a gray ratsnake climbed into a garage or an attic. Older foundations near German Village and sill gaps on Clintonville bungalows are both usable. Tell us if you have had both. The gap that fits a mouse is also the start of a squirrel or bat inspection.

Drip edge and the builder's gap
Newer roofs in New Albany, Powell, and Lewis Center, and older ones in Columbus, both show up without drip edge, or with a piece that stops short of the corner. We look behind the gutter line on an exclusion visit, not only at the vent you noticed.
Read the guideEave gaps and soffit returns
Columbus houses with long eaves, including ranches in Gahanna and newer gables in Hilliard, have soffit returns worth a look. A deck roof that ties back into the house, common in Powell, is a cousin of the same joint.
Read the guideFascia gaps
Older blocks in Columbus, Grandview Heights, and Worthington, plus roofs in Delaware that have been patched more than once, collect fascia gaps. We look for the patch an animal already reopened, not only the fresh chew.
Read the guideRidge vents and ridge guard
We see open ridge vents on older Columbus roofs and on newer subdivision roofs in Reynoldsburg and Pickerington. A metal ridge guard is part of an exclusion plan when the peak is the door. It does not replace checking soffits, fascia, and drip edge.
Read the guideRat walls
Around Columbus, the usual places are deck skirts, shed floors, and foundations on lots that back up to a field or a ditch, including the edges of Pickerington and Hilliard. We pair a rat wall with whatever is already denning there, and we do not bury mesh over an occupied burrow.
Read the guidePreventive wildlife seal-up
For Columbus and the towns around it, a seal-up is the exclusion visit: roofline and ground level, metal where something can chew, and no exterior bat seal during Ohio's restricted dates. We will say which openings your house has before anyone starts.
