Homeowners, renters and landlords in Houma who are hearing, seeing or smelling signs of rodents.
What to look for
A mouse fits through a gap the size of a dime. Seeing one in daylight usually means there are more. Rodents are mostly unseen. You hear them at night and find droppings by morning.
- 1Droppings in drawers, pantries, under sinks, or along walls.
- 2Disturbed insulation or tunnels in the attic.
- 3Chewed vehicle wiring or nesting under the hood.
- 4Tracks or tail drag marks in dust or flour.
- 5Pipe gaps stuffed with debris or looking chewed wider.
- 6Food scattered or hollowed-out fruit and nuts.
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.

- Outdoor rat pressure; ongoing perimeter protection
Attic and Crawlspace Cleanup and Sanitation
$500–$3,000, higher if insulation is replaced

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 Houma.
They're small, curious and breed quickly. Norway rats are the other usual suspect. They burrow along foundations and enter low. Roof rats are common around Houma too. They climb, and come in high through attic vents and branches. House mice are the most common rodent in Houma homes.
When they move in.
Roof rats are active all year. Listen for them in the attic after dark. Spring is breeding season. Small problems grow fast. Activity still rises in fall and winter, even here.
Fall is when rodents head indoors. Leaf piles against the foundation hide burrows and gaps, so clear them and walk the wall before the first cold snap.How they get into houses here.
Garage seals, brick weep holes and pipe gaps are typical entries. Check the bottom corners of the garage door. Look behind the washer and under sinks. Daylight under a door means a gap. Homes from Houma out to Kenner 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. Many homes in Houma sit on slabs.
A year of rodents in Houma.
- Fall: activity rises as rodents settle in for winter. Check the attic and garage. - Winter: with lows near 45°F in Houma, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 92°F in Houma, rodents look for water. Fix drips and leaks.
Mice or rats?
- 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. - 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.
Sealing small gaps yourself.
- Steel wool or copper mesh: pack it into small gaps first. - 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.
Cleaning up droppings safely.
- Air the room out for 30 minutes first. - 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.
What happens at an inspection.
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.
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. Check the air filter box for nesting.
Bird feeders and rodents.
Store seed in a metal can with a tight lid. Spilled seed feeds mice and rats. Use a seed tray and sweep up spills. If rodents show up, bring feeders in at night.
Questions to ask before you sign.
- Where are they getting in? - 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.)
Rodents by the numbers.
Across Houma, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. Across Houma, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Across Houma, 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.

- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Emergency or short-notice scheduling.
- Whether sheds, garages or other outbuildings are included.
- Number of trapping visits needed to reach zero.
- Follow-up visits included versus billed separately.

What you can do yourself

Rat-proofing gap size
LSU AgCenter: rat-proof all buildings by sealing all holes and openings larger than 0.5 inch.
LSU AgCenterBait or trap spacing for mice
Mice hide anywhere and do not move far from nests; glue boards and traps work where baits are not acceptable.
LSU AgCenterMinimum bait per placement
All rodenticides should go in tamperproof bait stations per the LSU guide.
LSU AgCenterRodent species recorded in Louisiana
- House mouse (Mus musculus) — Enters at 1/4 inch; 5-10 litters per year; eats about 200 small meals a night.
- Norway rat (Rattus norvegicus) — Burrowing rat of basements, sewers and ground floors; tail shorter than head plus body.
- Roof rat (Rattus rattus) — Climber of attics and trees in warm and coastal regions; tail longer than head plus body.
When rodents are busiest around Houma
Year-round, fall surge. Roof rats dominate Florida, Texas and Gulf Coast attics.

Simple ways to keep rodents away
- Fill gaps around pipes, cables, and AC lines with copper mesh.
- Insert metal weep-hole guards in brick veneer.
- Cover dryer and exhaust vents with metal louvered covers.
- Fit garage doors with tight bottom seals and corner guards.
- Declutter garages and attics to remove nesting cover.
- Seal the gap where the garage slab meets the wall.

Questions people ask
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 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.
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 Louisiana. Ask how they seal gaps and what materials they use.
Are snap traps better than poison?
Poisoned rodents can die inside walls and smell for weeks. Bait belongs in locked stations outside. Indoors, usually yes. Traps let you confirm the catch and remove it.
Can I just seal the holes myself?
Foam alone won't stop them. Rooflines and vents are harder, and that's where a pro helps. Small gaps, yes. Use steel wool or copper mesh, then seal over it.
How many homes in the U.S. have mice or rats?
homes reported rodent sightings or signs in the U.S. Census Bureau's 2019 American Housing Survey (AHS). About one in eight report them. Roughly one household in eight is dealing with mice or rats in a given year: 11.9% of occupied U.S.
