Anyone in New Iberia 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.
- 1Small dark droppings on top of the water heater.
- 2Droppings in drawers, pantries, under sinks, or along walls.
- 3Shredded paper, fabric, or insulation gathered into a nest.
- 4Greasy rub marks along baseboards, beams, and pipe runs.
- 5Bait or pet food vanishing from bowls overnight.
- 6Live sighting, especially during the day.
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 New Iberia that list is the real product.

Bathroom vanities hide the same plumbing gaps as the kitchen. A quick look with a flashlight shows droppings or rub marks long before you see a mouse.Which rodents live around New Iberia.
House mice are the most common rodent in New Iberia 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 New Iberia 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 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.
Many homes in New Iberia 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 New Iberia out to Lafayette 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 New Iberia.
- Fall: activity rises as rodents settle in for winter. Check the attic and garage. - Winter: with lows near 46°F in New Iberia, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 92°F in New Iberia, 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.
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. You should come away with a list of entry points. Photos help.
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.
- 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.
National surveys set rough expectations but cannot diagnose one house. In New Iberia, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. In New Iberia, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. In New Iberia, ask any provider to show you the entry points and the plan before you compare numbers.
What affects the price
- Follow-up visits included versus billed separately.
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Whether insulation must be removed and replaced.
- Mice versus rats; rats take longer and cost more.
- Sewer line inspection if rats are entering underground.
- Emergency or short-notice scheduling.

What's your biggest concern about rodents?
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.

Local research
Rodents in New Iberia, 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 Iberia, 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 Iberia
Year-round, fall surge. Roof rats dominate Florida, Texas and Gulf Coast attics.
Based on New Iberia’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
- Keep grass short and remove tall weeds along fences.
- Move compost bins away from the house and use closed models.
- Seal the gap where the garage slab meets the wall.
- Clean up pet waste and do not leave bowls out overnight.
- Fit garage doors with tight bottom seals and corner guards.
- Store pantry staples in glass or hard plastic.
After sealing, a few monitors or unset traps left along the walls tell you whether anything is still getting in before you hear it again.Did you know?

Questions people ask
How do I choose a rodent control company?
Make sure they're licensed in Louisiana. 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.
Will rodents leave on their own?
Rarely. Once they've found food, water and a warm nest, they stay.
Are rats a bigger problem than mice?
Usually. Rats are bigger, chew more, and avoid new traps for days. Around New Iberia, roof rats often nest in attics, so check the roofline too.
Will rodent control harm my pets?
It shouldn't. Traps go where pets can't reach. Bait stations are locked. Tell the company about your pets before they start.
Why do rodents keep coming back every year?
Usually because the entry points were never sealed. Traps remove the rodents inside. New ones follow the same path in.
Are families with kids more likely to have rodents?
The survey evidence suggests they report them more often. Among parents of under-18s in the National Pest Management Association's (NPMA) September 2022 Harris Poll of more than 1,300 U.S. homeowners, 68% reported a rodent encounter at some point, well above the 49% of homeowners overall. For a home in New Iberia, the next step is an inspection that finds the source.
How common are rodent problems in U.S. homes?
Very common. Forty-nine percent of U.S. homeowners told a September 2022 Harris Poll for the National Pest Management Association (NPMA) that they had encountered or had a problem with rodents at some point. Ask every New Iberia company you get a quote from what they tend to find in your part of town.
Are rodents a problem in New Iberia?
