- Deer MouseBi-colored rodents with white undersides and brown backs, common in rural and wooded areas, and a known carrier of hantavirus — droppings should be handled with care.
- Eastern Gray SquirrelCommon gray tree squirrels that can chew into attics and soffits to nest, causing damage to insulation and wiring. Most active seeking shelter in fall.
- House MouseSmall gray-brown rodents, 2.5 to 3.75 inches long (plus tail), that can squeeze through gaps as small as a dime. Signs include small dark droppings, gnaw marks, and greasy rub marks along walls.

- Roof RatSlender, agile rats, black to brown, that are excellent climbers and prefer nesting in attics, trees, and upper parts of structures rather than at ground level.
- VoleSmall, stocky rodents with short tails that create visible surface runways in lawns and gardens by chewing grass and feeding on roots and bulbs.
