What to look for
Rodents are mostly unseen. You hear them at night and find droppings by morning. A mouse fits through a gap the size of a dime. Seeing one in daylight usually means there are more.
- 1Pipe gaps stuffed with debris or looking chewed wider.
- 2Scratching or scurrying sounds in walls or ceilings at night.

- 6Shredded paper, fabric, or insulation gathered into a nest.
Why it’s worth acting soon
- Mice breed fast, every few weeks.
- Droppings and urine contaminate food and insulation.
- Gnawed wiring can be a fire risk.
- Nests and odor get harder to clean the longer they stay.

Roof rats and mice love attic insulation. Tunnels through the fluff, flattened runways and droppings along the eaves are the signs to look for.Which rodents live around Greenwood.
They burrow along foundations and enter low. Norway rats are the other usual suspect. They're small, curious and breed quickly. House mice are the most common rodent in Greenwood homes.
When they move in.
Spring is breeding season. Check for gaps before then. Small problems grow fast.

Mice or rats?

Rats avoid them for days. - Sounds: mice sound light and quick. Rats sound heavier. - Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized.
Sealing small gaps yourself.
- Steel wool or copper mesh: pack it into small gaps first. - Check your work: daylight through a gap means it isn’t sealed. - Expanding foam: fine on top of mesh, useless on its own. - Door sweeps: close the gap under garage and exterior doors. - Hardware cloth: use quarter-inch mesh over vents and larger holes. - Sealant or mortar: cover the mesh so it stays put.
Cleaning up droppings safely.
- Air the room out for 30 minutes first. - Wash your gloved hands, then your hands. - Don’t sweep or vacuum droppings dry. It stirs up dust. - Wipe up with paper towels and bag them. - Spray droppings with a bleach solution, then wait five minutes. - Wear rubber or plastic gloves.
What happens at an inspection.
They check the foundation, vents, rooflines and utility gaps. The inspector walks the outside first. Most inspections take about an hour. Photos help. You should come away with a list of entry points. Inside, they check the kitchen, garage and attic.
Rodents in the car.
Park in a closed garage when you can. Mice and rats nest in engine bays and chew wiring. Clear birdseed and pet food from the garage. Check the air filter box for nesting.
Bird feeders and rodents.
Use a seed tray and sweep up spills. Spilled seed feeds mice and rats. Store seed in a metal can with a tight lid. If rodents show up, bring feeders in at night.
Questions to ask before you sign.
- Where are they getting in? - Will you use poison inside? (Ask them not to.) - Is cleanup included, or extra? - What happens if they come back? - How many trap visits are included? - Which gaps will you seal, and with what?

Around Greenwood, ask any provider to show you the entry points and the plan before you compare numbers. Around Greenwood, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Around Greenwood, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. National surveys set rough expectations but cannot diagnose one house.
What affects the price
- Home size, stories, and roofline complexity.
- Whether insulation must be removed and replaced.
- Sewer line inspection if rats are entering underground.
- Number of trapping visits needed to reach zero.
- Local labor rates and licensing costs.

Questions people ask
What does a rodent inspection involve?
Inside, they look at the kitchen, attic, garage and under sinks. You should get a list of entry points. The inspector checks the outside walls, roofline, vents and utility gaps.
Why do rodents keep coming back every year?
Traps remove the rodents inside. New ones follow the same path in. Usually because the entry points were never sealed.
Do ultrasonic repellers work?
It doesn't pass through walls either. Sealing and trapping work better. Not reliably. Rodents get used to the sound within days.
Is it safe to clean up droppings myself?
Wait five minutes, then wipe up with paper towels. Never sweep or vacuum them dry. For small amounts, yes, with care. Wear gloves and spray the droppings with a bleach solution.
What is rodent-proofing and why does it cost so much?
A mouse fits through a dime-sized gap, so it's slow work. It's also the part that keeps them out. It means sealing every gap with metal mesh and sealant.
Is one mouse in the house a sign of an infestation?
Thirty-seven percent of U.S. homeowners in a September 2022 Harris Poll for the National Pest Management Association (NPMA) said their rodent experience involved a single animal.
