What to Expect From a Rodent Inspection

How long it takes

For a typical single-family Ohio home, plan on 45 minutes to an hour and a half. Larger homes, older homes with stone foundations, homes with crawlspaces and properties with detached garages or outbuildings take longer. If someone finishes in fifteen minutes without going into the basement, attic and garage, they have not done a real inspection.

What the technician checks

1. Outside at ground level: the full foundation, garage door corners, utility penetrations, weep holes, vents, crawlspace openings, porches and decks.
2. The yard: burrows along slabs, fences, sheds and retaining walls, runways through grass, and food sources like bird feeders and compost.
3. The roofline: soffits, gable vents, roof returns and overhanging branches, from the ground or a ladder.
4. The basement or crawlspace: the sill plate, foundation walls, pipe and wire penetrations, windows, coal chutes and floor drains.
5. The kitchen, bathrooms and laundry: under sinks, behind appliances, pantry shelves.
6. The attic and knee walls: insulation tunnels, droppings near the eaves and top plates.
7. The garage: door seals, the shared wall with the house and stored food.

What you should get at the end

A good inspection ends with a clear explanation: which rodent you have, where they are active, how they are getting in, and what the plan is. Ideally you get it in writing, with each entry point listed and the material that will be used to close it, plus a price range for trapping and for sealing as separate line items. Ask to see photos of what they found if you could not go into the attic or crawlspace yourself.

How to prepare your home

• Clear a path along basement and garage walls so the sill and foundation are visible.
• Empty the cabinet under the kitchen sink.
• Make the attic hatch and any knee-wall doors accessible.
• Leave droppings where you found them so the technician can see them, but keep kids and pets away.
• Note where and when you heard noises, and where you found droppings.
• Put pets in a closed room during the visit.

Questions to ask before you agree to treatment

• Is this rats or mice, and how can you tell?
• Where are they getting in, and can you show me?
• Will you use poison inside the house, or traps? (Traps inside avoid dead rodents in walls.)
• How many visits are included, and what do extra visits cost?
• Is sealing included, and what materials will you use?
• What is your Ohio pest control license number?
• Do you offer any warranty on the sealing work, and can I have the terms in writing?

Red flags

Be cautious of anyone who skips the attic and basement, cannot tell you where the rodents are getting in, quotes only monthly bait service with no sealing, plans to scatter loose poison inside the living space, or pressures you to sign a long contract on the spot. A good technician explains the problem in plain language and lets you decide. See mouse control and rat removal for what a complete job includes.

What happens after the inspection

If you agree to treatment, traps usually go in on the same visit, along the runways the technician found. Locked stations go outside if there are rats. Some sealing may be done right away, especially obvious gaps like a torn garage door seal; larger work, like foundation mortar or roofline sealing, is often scheduled for the second visit once trapping is underway. A follow-up visit a week or two later clears traps, checks for new activity and confirms the sealing worked.

Keep notes between visits. If you hear new noises or find fresh droppings, tell the technician on the next visit or call in between.

Inspections when buying or renting a home

If you are buying an older Ohio home, a general home inspection may note droppings or chewed insulation but rarely traces entry points. A separate rodent inspection before closing tells you what sealing will cost. Renters who find signs of mice should report them to the landlord in writing; Ohio landlords are generally responsible for keeping rental units fit and habitable.

Inspections for rats versus mice

A rat inspection spends more time outside: walking the lot, the alley, fences, porches and garage slabs for burrows and runways, and looking at the floor drain inside. A mouse inspection spends more time in the house: the sill plate, kitchen cabinets, knee walls and attic. If you are not sure which you have, the technician will tell you from the droppings and gnaw marks.

Inspections for landlords with several properties

Ohio landlords with several older rentals often save money by having them inspected in one round, ideally in late summer before the fall rush. A technician can compare similar houses, spot the gaps they share and seal them all at once. Between tenants is also a good time, when kitchens and basements are empty and easy to check. A written list of findings for each unit also helps if a tenant later reports mice.
