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.

Crawl spaces are where rats and mice get comfortable. Vent screens, the sill plate and any gap around pipes are worth a careful look.Which rodents live around Brentwood.
They burrow along foundations and enter low. Roof rats turn up in parts of Tennessee. They climb and come in high, through attics and rooflines. House mice are the most common rodent in Brentwood homes. They're small, curious and breed quickly. Norway rats are the other usual suspect.
When they move in.
Check for gaps before then. Spring is breeding season. Small problems grow fast.
A metal vent cover with a working flap keeps mice out all winter. Plastic flaps crack in the cold and get chewed open.How they get into houses here.
Check that vent screens are intact. Make sure the crawl door closes tight. Look for gaps where pipes and wires pass through the floor. Homes from Brentwood out to Nashville and Franklin share the same weak spots, so the checklist below works across the area. For roof rats, check soffit vents, gable vents and eaves.

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

What affects the price
- Crawlspace or slab; crawlspaces add labor.
- Whether insulation must be removed and replaced.
- Exterior bait stations and ongoing service frequency.
- Local labor rates and licensing costs.
- Emergency or short-notice scheduling.
- Outdoor pressure from creeks, alleys, or restaurants nearby.

What's your biggest concern about rodents?
When to call for help
Call right away if you see rats. They take a longer, more careful approach. Attic cleanup is hard to do safely without training. Call if you hear them in the attic or walls. Droppings in several rooms are another sign. So is a dead-rodent smell.
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.

Questions people ask
How do I choose a rodent control company?
Ask what happens if rodents come back. A good company talks about sealing, not just traps. Make sure they're licensed in Tennessee. Ask how they seal gaps and what materials they use.
What should be in a rodent control quote?
It should say what happens if they return. Cleanup should be listed separately. Entry points, sealing materials and the number of trap visits.
How do I know if I have mice or rats?
Mouse droppings are about the size of a rice grain. Rats also chew larger holes and sound heavier at night. Check the droppings.
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.
