Anyone in Smyrna dealing with mice or rats, or hoping to keep them out.
What to look for
Seeing one in daylight usually means there are more. A mouse fits through a gap the size of a dime. You hear them at night and find droppings by morning. Rodents are mostly unseen.
- 1Scratching or scurrying sounds in walls or ceilings at night.
- 2Live sighting, especially during the day.
- 3Food scattered or hollowed-out fruit and nuts.
- 4Fresh gnaw marks on door corners or garage weatherstripping.
- 5Pets staring at or pawing at a wall or appliance.
- 6A musky or ammonia-like smell in closed rooms.
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.
Treatment options and typical costs
Inspection and Entry-Point Mapping
$75–$250
Many credit the fee if you go ahead. Ask. Ask whether the report lists every entry point, because in Smyrna that list is the real product.
- Time
- 60–90 minutes
- Best for
- Every job; nothing else works without it
Snap-Trap Program
$150–$400 per visit

- Best for
- Active indoor infestations; fast results you can see
Attic and Crawlspace Cleanup and Sanitation
$500–$3,000, higher if insulation is replaced
Scent trails attract new rodents. Cleanup helps the sealing hold. Deodorizing and sealing a Smyrna attic makes it less inviting to the mice outside looking for a way in.
- Time
- Half day to two days
- Best for
- Heavy contamination; odor, urine-soaked insulation, nesting
Follow-Up Monitoring
$50–$150 per visit, or included in a plan

Rats can travel plumbing, so a sink or floor drain with a missing strainer is worth fixing; a tight strainer or grate keeps them out.Which rodents live around Smyrna.
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 Smyrna homes. They're small, curious and breed quickly. Norway rats are the other usual suspect.
When they move in.
Spring is breeding season. Small problems grow fast. Check for gaps before then.
Dense shrubs against the house and a dripping hose bib give rodents cover and water. Trimming back and fixing drips makes the yard less inviting.How they get into houses here.
Look for gaps where pipes and wires pass through the floor. Homes from Smyrna out to Murfreesboro and Brentwood share the same weak spots, so the checklist below works across the area. For roof rats, check soffit vents, gable vents and eaves. Trim branches back from the roof. A lot of houses around Smyrna have crawl spaces, and crawl vents and access doors are the usual way in. Check that vent screens are intact. Make sure the crawl door closes tight.
A year of rodents in Smyrna.
- Winter: with lows near 29°F in Smyrna, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 90°F in Smyrna, rodents look for water. Fix drips and leaks. - Fall: rodents look for shelter. Seal gaps before cold nights arrive.
Mice or rats?
- Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized. - Sounds: mice sound light and quick. Rats sound heavier. - Behavior: mice are curious about new traps. 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.
Sealing small gaps yourself.
- Sealant or mortar: cover the mesh so it stays put. - 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.
Cleaning up droppings safely.
- Wear rubber or plastic gloves. - 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.
What happens at an inspection.
Inside, they check the kitchen, garage and attic. 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.
Rodents in the car.
Check the air filter box for nesting. Clear birdseed and pet food from the garage. Mice and rats nest in engine bays and chew wiring. Park in a closed garage when you can.
Bird feeders and rodents.
If rodents show up, bring feeders in at night. Store seed in a metal can with a tight lid. Spilled seed feeds mice and rats. Use a seed tray and sweep up spills.
Questions to ask before you sign.
- Which gaps will you seal, and with what? - 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?
Rodents by the numbers.
For Smyrna homes, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. For Smyrna homes, ask any provider to show you the entry points and the plan before you compare numbers. National surveys set rough expectations but cannot diagnose one house. For Smyrna homes, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is.
What affects the price
- Crawlspace or slab; crawlspaces add labor.
- Materials used for sealing: mesh, sheet metal, mortar.
- Number of trapping visits needed to reach zero.
- Number of entry points found during inspection.
- Whether insulation must be removed and replaced.
- Whether sheds, garages or other outbuildings are included.

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?
Make sure they're licensed in Tennessee. 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.
Do I need to replace attic insulation?
Only if it's heavily soiled or flattened by nesting. Light activity can often be cleaned up. Ask the inspector to show you before you agree to replacement.
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.
Is it safe to clean up droppings myself?
For small amounts, yes, with care. Wear gloves and spray the droppings with a bleach solution. Wait five minutes, then wipe up with paper towels. Never sweep or vacuum them dry.
Are families with kids more likely to have rodents?
The survey evidence suggests they report them more often. Households with children were the most likely group to report a rodent encounter in the 2022 NPMA/Harris Poll of U.S. homeowners, at 68%. Families with young children may want to be extra careful about food storage. For a home in Smyrna, the next step is an inspection that finds the source.
Are rodent problems in U.S. homes getting worse?
Not noticeably, on the national numbers. Calculated from the published figures of the U.S. Census Bureau's 2023 American Housing Survey (AHS), about 11.8% of occupied U.S. homes (15.7 million of 133.2 million, rounded) reported rodent signs in the previous year. Ask every Smyrna company you get a quote from what they tend to find in your part of town.
Are rodents a problem in Smyrna?
