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.

Why it’s worth acting soon

Bathroom vanities hide the same plumbing gaps as the kitchen. A quick look with a flashlight shows droppings or rub marks long before you see a mouse.Which rodents live around Greer.
They climb, and come in high through attic vents and branches. Roof rats are common around Greer too. 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 Greer homes.
When they move in.
Small problems grow fast. Spring is breeding season. Listen for them in the attic after dark. Roof rats are active all year. Check for gaps before then.
This is what a proper seal looks like: metal mesh fastened with screws and sealed at the edges. Foam or caulk on its own gets chewed through.How they get into houses here.
Trim branches back from the roof. For roof rats, check soffit vents, gable vents and eaves. Homes from Greer out to Taylors and Greenville share the same weak spots, so the checklist below works across the area. Look for gaps where pipes and wires pass through the floor. Make sure the crawl door closes tight. Check that vent screens are intact. A lot of houses around Greer have crawl spaces, and crawl vents and access doors are the usual way in.
A year of rodents in Greer.
- Summer: with highs around 89°F in Greer, rodents look for water. Fix drips and leaks. - Spring: breeding season. Act on any sign quickly. - Winter: with lows near 32°F in Greer, check the attic, garage and pantry for droppings. - Fall: rodents look for shelter. Seal gaps before cold nights arrive.
Mice or rats?
- Rub marks: rats leave greasy smudges along walls and beams. - Behavior: mice are curious about new traps. 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. - Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger.
Sealing small gaps yourself.
- 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. - Steel wool or copper mesh: pack it into small gaps first.
Cleaning up droppings safely.
- 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. - Air the room out for 30 minutes first.
What happens at an inspection.
Photos help. You should come away with a list of entry points. They'll also check the crawl space. Inside, they check the kitchen, garage and attic. They check the foundation, vents, rooflines and utility gaps. The inspector walks the outside first. Most inspections take about an hour.
Rodents in the car.
Clear birdseed and pet food from the garage. Check the air filter box for nesting. Park in a closed garage when you can. Mice and rats nest in engine bays and chew wiring.
Bird feeders and rodents.
Store seed in a metal can with a tight lid. If rodents show up, bring feeders in at night. Use a seed tray and sweep up spills. Spilled seed feeds mice and rats.
Questions to ask before you sign.
- 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? - Where are they getting in?
Rodents by the numbers.
Around Greer, ask any provider to show you the entry points and the plan before you compare numbers. Around Greer, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Around Greer, 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
- Follow-up visits included versus billed separately.
- Home size, stories, and roofline complexity.
- Sewer line inspection if rats are entering underground.
- Emergency or short-notice scheduling.
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Attic access and how much insulation is contaminated.

When to call for help
Attic cleanup is hard to do safely without training. They take a longer, more careful approach. Call right away if you see rats. So is a dead-rodent smell. Droppings in several rooms are another sign. Call if you hear them in the attic or walls.
What you can do yourself
That's where a pro's sealing work pays off. Rooflines, vents and attics are harder. Seal small gaps with steel wool and sealant. Store food in sealed bins. Bait them with peanut butter. Start tonight with snap traps along the walls.
