The short version
Trap the ones inside, then seal the gaps. Around Kenner, check the roofline too, since roof rats come in high. An inspection usually costs $75–$250.
- Look for droppings, gnaw marks and night-time scratching.
- Winters around Kenner are mild, so rodents stay active all year.
- Traps remove them; sealing keeps them out.
- Never sweep or vacuum droppings dry.
Anyone in Kenner dealing with mice or rats, or hoping to keep them out.
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.
- 1Rodent hair or droppings inside HVAC ducts.
- 2Food scattered or hollowed-out fruit and nuts.
- 3Chewed holes in the bottom of cabinets or drawers.
- 4Greasy rub marks along baseboards, beams, and pipe runs.
- 5Dead-animal odor that appears and slowly fades.
- 6Pipe gaps stuffed with debris or looking chewed wider.
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
A Kenner rodent inspection starts with a walk outside, looking for gaps along the foundation, roofline and utility lines. Then they check attics, crawlspaces and appliances inside.
- Time
- 60–90 minutes
- Best for
- Every job; nothing else works without it
Tamper-Resistant Exterior Bait Stations
$100–$300 setup, $40–$80 per service visit
Bait stations belong outside, not in the attic. A Kenner pro places them along fence lines, near sheds, and beside foundations where rats travel, then services them monthly or quarterly.
- Time
- 30–45 minutes per visit, ongoing
- Best for
- Outdoor rat pressure; ongoing perimeter protection
Attic and Crawlspace Cleanup and Sanitation
$500–$3,000, higher if insulation is replaced
Soaked or matted insulation usually has to be replaced. That drives the top of the range in Kenner, so ask for a separate line item for insulation.
- 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
Ask what happens if activity returns during the monitoring period. Many re-trap and re-seal under the same agreement. Confirm first.
- Time
- 20–40 minutes per visit
- Best for
- Confirming the house stays clear after treatment
Prices are typical published ranges. Ask what’s included before you compare quotes.
Clutter gives mice cover. Keeping stored fabric in lidded bins and off the floor takes away the nesting spots they like best.Which rodents live around Kenner.
House mice are the most common rodent in Kenner homes. 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 Kenner too. They climb, and come in high through attic vents and branches.
When they move in.
Activity still rises in fall and winter, even here. Roof rats are active all year. Listen for them in the attic after dark. Spring is breeding season. Small problems grow fast.
A good inspection starts outside at ground level: door thresholds, the joint between siding and foundation, and anywhere a pipe or cable enters.How they get into houses here.
Many homes in Kenner 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. Daylight under a door means a gap. Homes from Kenner out to New Orleans and Gretna 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 year of rodents in Kenner.
- Winter: with lows near 46°F in Kenner, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 91°F in Kenner, rodents look for water. Fix drips and leaks. - Fall: activity rises as rodents settle in for winter. Check the attic and garage.
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. 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.
National surveys set rough expectations but cannot diagnose one house. In Kenner, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. In Kenner, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. In Kenner, ask any provider to show you the entry points and the plan before you compare numbers.
What affects the price
- Exterior bait stations and ongoing service frequency.
- Number of entry points found during inspection.
- Follow-up visits included versus billed separately.
- Sewer line inspection if rats are entering underground.
- Age of the home and condition of the foundation.
- Whether insulation must be removed and replaced.

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
Seal small gaps with steel wool and sealant. Rooflines, vents and attics are harder. That's where a pro's sealing work pays off. Start tonight with snap traps along the walls. Bait them with peanut butter. Store food in sealed bins.

Local research
Rodents in Kenner, 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 Kenner, 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 Kenner
Year-round, fall surge. Roof rats dominate Florida, Texas and Gulf Coast attics.
Based on Kenner’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.

Simple ways to keep rodents away
- Move compost bins away from the house and use closed models.
- Fill gaps around pipes, cables, and AC lines with copper mesh.
- Screen foundation and attic vents with quarter-inch hardware cloth.
- Fix leaking hoses, faucets, and irrigation heads.
- Check crawlspace doors and vents for chewed openings each fall.
- Store pet food and birdseed in sealed metal containers.
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?
A house mouse can jump about a foot straight up.
In Kenner, rats make ultrasonic chirps when they're tickled, which researchers compare to laughter.
Questions people ask
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.
Why do rodents keep coming back every year?
Traps remove the rodents inside. New ones follow the same path in. Usually because the entry points were never sealed.
Do I need to replace attic insulation?
Light activity can often be cleaned up. Ask the inspector to show you before you agree to replacement. Only if it's heavily soiled or flattened by nesting.
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.
How long does rodent control take?
Most jobs take two to four weeks. That covers inspection, sealing and a few trap checks.
Which parts of the U.S. have the most rodent problems?
Census Bureau's 2019 American Housing Survey (AHS). For a home in Kenner, the next step is an inspection that finds the source. Older, denser metros in the Northeast report far more. Where you live matters: reported rodent signs ranged from 3.1% to 18.9% of homes across the large metros in the U.S.
Do wealthier homes get fewer mice and rats?
Fifty-two percent of U.S. homeowners with household incomes of $100,000 or more reported a rodent encounter at some point in their lives in a September 2022 Harris Poll for the National Pest Management Association (NPMA). Not according to homeowner surveys.
Are rodents a problem in Kenner?
They're common here, as almost everywhere. Roof rats are also common in the area.
