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 Spartanburg out to Greer and Taylors share the same weak spots, so the checklist below works across the area. Look for gaps where pipes and wires pass through the floor.

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.

National surveys set rough expectations but cannot diagnose one house.
What affects the price
- Emergency or short-notice scheduling.
- Number of entry points found during inspection.
- Home size, stories, and roofline complexity.
- Attic access and how much insulation is contaminated.
- Number of trapping visits needed to reach zero.
- Exterior bait stations and ongoing service frequency.

Questions people ask
What should be in a rodent control quote?
Entry points, sealing materials and the number of trap visits. It should say what happens if they return. Cleanup should be listed separately.
What is rodent-proofing and why does it cost so much?
It means sealing every gap with metal mesh and sealant. A mouse fits through a dime-sized gap, so it's slow work. It's also the part that keeps them out.
Are snap traps better than poison?
Indoors, usually yes. Traps let you confirm the catch and remove it. Poisoned rodents can die inside walls and smell for weeks. Bait belongs in locked stations outside.
How do I choose a rodent control company?
Make sure they're licensed in South Carolina. Ask how they seal gaps and what materials they use. Ask what happens if rodents come back. A good company talks about sealing, not just traps.
How do I know if I have mice or rats?
Check the droppings. Mouse droppings are about the size of a rice grain. Rats also chew larger holes and sound heavier at night.
Does a house with structural problems attract more rodents?
The two go together, at least in the data. Homes with sloping, leaning or buckling outside walls were 5.6 times as likely to report rodent sightings in the U.S. Census Bureau's 2019 American Housing Survey (AHS). For a Spartanburg home, the next step is an inspection that tracks down where they're coming from.
How many homes in the U.S. have mice or rats?
About one in eight report them. The U.S. Census Bureau's 2019 American Housing Survey (AHS) found that 11.9% of occupied homes had seen rodents or evidence of them in the preceding year.
