Rat Control in Columbus, OH

Norway rats in Ohio: what they are and how to spot them

The rat in most Ohio yards is the Norway rat. It is a heavy-bodied animal, often seven to nine inches long before the tail, and it prefers ground level: burrows, basements, crawlspaces and garages. It will climb to reach food, but it starts low.

Signs are bigger than mouse signs, and easier to find outside:

• Droppings about the size of a capsule, often three quarters of an inch long, in clusters near food or along walls
• Gnaw marks on wood, plastic and bags that are wide and rough, not fine like a mouse's
• Smooth, dark rub marks along fences, foundations and pipes
• Burrow holes two to three inches across, with packed dirt and no webs
• Chewed trash bags, torn garbage bins and gnawed pet food bins

If you are not sure whether the signs point to a mouse or a rat, our guide on telling a mouse from a rat is a good first read, and mouse control covers the smaller animal.

Are those burrows along your foundation from rats?

Often, yes. A rat burrow is a round hole two to three inches wide, usually against a foundation, under a slab, a shed or a woodpile, or beside a compost bin. The dirt at the mouth is packed smooth from traffic. Spider webs across the opening mean nobody is using it.

Other animals dig holes too, so look for evidence of use: fresh dirt, a polished edge, droppings nearby and a trail worn through grass or mulch. Rat burrows tend to have more than one opening. Do not fill them in before we look, since a plugged burrow tells the rats to dig a new one next to it, possibly closer to the house.

How far does a rat travel from its burrow?

Norway rats forage 100 to 500 feet from the nest at night, according to the University of California's IPM program. The burrow behind your garage may be feeding at a dumpster two lots over. A female has 4 to 6 litters a year and can wean 20 or more young annually, which is why a small problem should not wait.

What attracts rats to a Columbus yard, garage or alley?

Food and cover, in that order. Orkin's 2026 rattiest cities list has Columbus at No. 15, up 6 spots, and the factors behind that are the same ones you can see on your own block. Rats need very little to settle in. These are the usual draws:

• Garbage cans without tight lids, and bags left beside a full dumpster
• Pet food or spilled seed left outside overnight
• Fallen fruit, compost piles and dog waste in the yard
• Woodpiles, stacked pallets and overgrown ivy that give cover along a fence
• Garages used for storage, where cardboard boxes and a gap under the door make a ready nest

The garage is where yard problems turn into house problems. A gap beneath the door or a missing corner seal lets a rat walk in and nest behind boxes. Our post on rodent-proofing a garage and basement covers the fixes, and you can read how the city ranking connects to your own block in what to do about the rat ranking.

How do you keep rats out of a Columbus garage or basement?

Rats can squeeze under a door through a half-inch gap. Walk the garage and basement with a flashlight and fix these first:

• Replace a cracked or missing bottom seal on the garage door
• Move stored goods from cardboard into lidded plastic bins, off the floor
• Keep pet food and birdseed in metal bins with tight lids
• Seal pipe and wire openings where they pass through the wall

Can rats come up through a drain?

Yes. Norway rats swim, and they can enter through broken or uncovered drains and sewer lines. A basement floor drain with a missing cover is a quiet doorway. A cracked sewer lateral is a plumber's job, not a trap's, and fixing it is the only way to close that route.

Rat removal in Columbus: how the work is done

Rats learn. They avoid new objects for days, so the placement matters more than the product. Our plan rests on three parts:

• Bait stations, which are locked, tamper-resistant boxes holding rodenticide applied per label directions, set along walls, fences and burrow runs. Stations stay put so rats get used to them.
• Traps, larger than mouse traps and often used indoors or where bait is a concern. They also let us confirm what was caught.
• Exclusion, which means sealing the gaps rats use to enter the house, garage or crawlspace. See rodent proofing for the materials and process.

Rodent baits are pesticides, and Ohio requires any company applying them for hire to hold an ODA Pesticide Business License. You can look up a company on ODA's online business search before you hire.

Sanitation is the part only you can do. If the food source stays, new rats replace the ones we remove. We tell you what we see and what to change.

What does a rat control visit look like, step by step?

1. You describe what you have seenBurrows, droppings, daytime sightings and noises tell us whether it is a yard problem, a house problem or both.
2. We ask about pets, children and allergiesBait station and trap placement depends on who and what can reach them, so we ask first and again at each visit.
3. We walk the yard, garage and foundationWe look for burrows, runways and gaps, then check the basement or crawlspace and the garage.
4. We set bait stations and trapsThey go where the rats travel. We explain where each one is and how to avoid them.
5. We return and sealReturn visits check the stations and traps. When activity drops, we close entry points. The schedule depends on how established the rats are.

Rat infestation in Columbus, Ohio: alleys, rentals and who handles it

A rat problem often crosses property lines. The dumpster behind a building, the neighbor's compost and an alley behind a row of houses can all be part of the same colony. We treat what we can reach on your property and tell you what is outside it.

If the alley is public, report the problem through the city's 311 service. If you rent in a building with two or more units, Columbus Health Code makes the owner responsible for eliminating pests (Columbus Public Health), so tell the landlord in writing. Owners and managers can call us to set up a schedule.

How much does rat removal cost?

We price rat work by how established the rats are, how much of the property is involved and how many entry points need sealing. Pricing is explained before work starts. A single burrow near a shed is a different job from a colony with access to a garage, a crawlspace and the neighbor's yard.

Several things push the number up: multiple burrows, large lots, difficult access under decks and slabs, and food sources the household cannot remove quickly. We will tell you what applies to your property and what you can do to keep the plan short.

Rat baiting in Columbus: EPA label rules and the city rodent code

Rat bait is a pesticide, so federal label law decides how it is used. EPA says professional rodenticide labels require tamper-resistant bait stations wherever children under six, pets or other animals can reach the bait, and for every above-ground outdoor placement. Outdoor burrow baiting is allowed only with pelleted bait placed at least six inches down an active burrow.

Ohio adds the business side: a company that applies pesticides for hire needs an ODA Pesticide Business License, and ODA's public search shows who holds one. In Columbus, Health Code §221.03 expects dwellings to be kept rodent-free. Ask any company where each station will sit, what product is in it and when someone will check it.
