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. Winters around New Orleans are mild, so rodents stay active all year. Seeing one in daylight usually means there are more.
- 1Droppings in drawers, pantries, under sinks, or along walls.
- 2Rodent hair or droppings inside HVAC ducts.
- 3A musky or ammonia-like smell in closed rooms.
- 4Tracks or tail drag marks in dust or flour.
- 5Live sighting, especially during the day.
- 6Chewed holes in the bottom of cabinets or drawers.
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
First, the pro maps where rodents get in. That map guides the traps and sealing.
- Time
- 60–90 minutes
- Best for
- Every job; nothing else works without it
Follow-Up Monitoring
$50–$150 per visit, or included in a plan
A good follow-up visit is short but thorough. The pro walks the New Orleans home's sealed points, checks any exterior stations, and updates you on what they found.
- Time
- 20–40 minutes per visit
- Best for
- Confirming the house stays clear after treatment
Tamper-Resistant Exterior Bait Stations
$100–$300 setup, $40–$80 per service visit
Stations should be numbered and logged to show activity trends. A good pro shows you which stations get hit. Placement changes over time.
- Time
- 30–45 minutes per visit, ongoing
- Best for
- Outdoor rat pressure; ongoing perimeter protection
Snap-Trap Program
$150–$400 per visit
Placement matters more than bait. Rodents run along edges, so traps in New Orleans attics and kitchens go perpendicular to walls, in the dark corners where droppings cluster.
- Time
- 30–60 minutes per visit, 2–4 visits
- Best for
- Active indoor infestations; fast results you can see

Which rodents live around New Orleans.
They burrow along foundations and enter low. Roof rats are common around New Orleans too. They climb, and come in high through attic vents and branches. House mice are the most common rodent in New Orleans homes. They're small, curious and breed quickly. Norway rats are the other usual suspect.
A metal vent cover with a working flap keeps mice out all winter. Plastic flaps crack in the cold and get chewed open.When they move in.
Listen for them in the attic after dark. Roof rats are active all year. Activity still rises in fall and winter, even here. Small problems grow fast. Spring is breeding season.
How they get into houses here.
Daylight under a door means a gap. Homes from New Orleans out to Gretna and 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 New Orleans sit on slabs. 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.
A year of rodents in New Orleans.
- Spring: breeding season. Act on any sign quickly. - Winter: with lows near 45°F in New Orleans, check the attic, garage and pantry for droppings. - Fall: activity rises as rodents settle in for winter. Check the attic and garage. - Summer: with highs around 91°F in New Orleans, rodents look for water. Fix drips and leaks.
Mice or rats?
- 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. - Rub marks: rats leave greasy smudges along walls and beams.
Sealing small gaps yourself.
- 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. - Check your work: daylight through a gap means it isn’t sealed.
Cleaning up droppings safely.
- 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. - Wash your gloved hands, then your hands.
What happens at an inspection.
They check the foundation, vents, rooflines and utility gaps. The inspector walks the outside first. Most inspections take about an hour. Photos help. You should come away with a list of entry points. Inside, they check the kitchen, garage and attic.
Rodents in the car.
Park in a closed garage when you can. Mice and rats nest in engine bays and chew wiring. Clear birdseed and pet food from the garage. Check the air filter box for nesting.
Bird feeders and rodents.
Use a seed tray and sweep up spills. Spilled seed feeds mice and rats. Store seed in a metal can with a tight lid. If rodents show up, bring feeders in at night.
Questions to ask before you sign.
- 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? - Will you use poison inside? (Ask them not to.)
Ways to keep the cost down.
- Act early, before rodents spread to the attic. - Store food and pet food in sealed bins. - Clear clutter so gaps are easy to reach. - Compare what each quote seals, not just the price.
Rodents by the numbers.
For New Orleans homes, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. For New Orleans 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 New Orleans 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
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Attic access and how much insulation is contaminated.
- Mice versus rats; rats take longer and cost more.
- Materials used for sealing: mesh, sheet metal, mortar.
- Age of the home and condition of the foundation.
- Follow-up visits included versus billed separately.
- Whether sheds, garages or other outbuildings are included.
- Crawlspace or slab; crawlspaces add labor.

What's your biggest concern about rodent control costs?
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
Start tonight with snap traps along the walls. Bait them with peanut butter. Store food in sealed bins. Seal small gaps with steel wool and sealant. Rooflines, vents and attics are harder. That's where a pro's sealing work pays off.
Rodents in New Orleans
A typical home in New Orleans is worth around $245k, and chewed wiring or soiled insulation can get expensive. In denser parts of New Orleans, rats travel along alleys, fences and utility lines, so neighbors often share the problem. Winter lows average around 45°F in New Orleans, so there's little pressure to move indoors, and activity stays steady. New Orleans gets about 64 inches of rain a year, and heavy storms flood burrows, which pushes rats toward buildings.
Local research
Rodents in New Orleans, LA: what the public record shows
Before you compare quotes, it helps to know which rodents actually live in Louisiana, when they are busiest around New Orleans, and what the state figures look like. Everything below links to the agency or university page it came from.
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 New Orleans
Year-round, fall surge. Roof rats dominate Florida, Texas and Gulf Coast attics.
Based on New Orleans’s humid subtropical climate profile.
LSU AgCenter's guide treats Norway rats, roof rats and house mice together; mice nest in appliances and chew wiring and can carry the same diseases as rats.
Rules that apply in Louisiana
For context, nationally
- 1/4 inch (the width of a pencil) — Smallest gap a mouse can enter. CDC
- 890; 35% fatal; 94% west of the Mississippi — Hantavirus cases reported since 1993 (through 2023). CDC

Simple ways to keep rodents away
- Walk the exterior each season looking for fresh gnawing.
- Check crawlspace doors and vents for chewed openings each fall.
- Declutter garages and attics to remove nesting cover.
- Take bird feeders down or use catch trays for spilled seed.
- Clean up pet waste and do not leave bowls out overnight.
- Cap chimneys and repair damaged roof vents.
A good rodent quote lists the inspection, the number of trapping visits, each opening to be sealed and the material for it, and any cleanup.Did you know?
Male house mice sing ultrasonic songs that humans can't hear.
For New Orleans homes, rodents make up about 40 percent of all mammal species on Earth.
Questions people ask
Does home size change the price?
Attics and crawl spaces add time too. Bigger houses have more walls and roofline to seal. Yes.
What does a rodent inspection cost?
It's worth asking. Some companies credit it toward the job if you go ahead. Usually $75–$250.
Is a quarterly rodent plan worth it?
For a one-time issue, a single sealing job is often enough. Homes near fields or water benefit most. It can be, after repeat problems.
What do exterior bait stations cost?
Usually a setup fee plus a monthly or quarterly service charge. Ask how many stations they'll use and how often they're checked.
Is it safe to clean up droppings myself?
Never sweep or vacuum them dry. Wait five minutes, then wipe up with paper towels. Wear gloves and spray the droppings with a bleach solution. For small amounts, yes, with care.
How long does rodent control take?
Most jobs take two to four weeks. That covers inspection, sealing and a few trap checks.
Can I just seal the holes myself?
Rooflines and vents are harder, and that's where a pro helps. Foam alone won't stop them. Use steel wool or copper mesh, then seal over it. Small gaps, yes.
Does a house with structural problems attract more rodents?
Census Bureau's 2019 American Housing Survey (AHS). Homes with sloping, leaning or buckling outside walls were 5.6 times as likely to report rodent sightings in the U.S. The two go together, at least in the data.
Which parts of the U.S. have the most rodent problems?
A good New Orleans pro will walk you through how the plan matches what they found at your place. Where you live matters: reported rodent signs ranged from 3.1% to 18.9% of homes across the large metros in the U.S. Older, denser metros in the Northeast report far more.
Are rodents a problem in New Orleans?
They're common here, as almost everywhere. Roof rats are also common in the area.
