Treatment options and typical costs
Inspection and Entry-Point Mapping
$75–$250

- 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
Sealing and Rodent-Proofing
$200–$1,500, more for large or complex homes

- Best for
- Stopping re-entry for good; the lasting fix
Attic and Crawlspace Cleanup and Sanitation
$500–$3,000, higher if insulation is replaced

Which rodents live around Baton Rouge.
They burrow along foundations and enter low. Roof rats are common around Baton Rouge too. They climb, and come in high through attic vents and branches. House mice are the most common rodent in Baton Rouge 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. Spring is breeding season. Small problems grow fast. Activity still rises in fall and winter, even here. Roof rats are active all year.
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. For roof rats, check soffit vents, gable vents and eaves. Trim branches back from the roof. Many homes in Baton Rouge sit on slabs.
A year of rodents in Baton Rouge.
- Spring: breeding season. Act on any sign quickly. - Summer: with highs around 92°F in Baton Rouge, rodents look for water. Fix drips and leaks. - Fall: activity rises as rodents settle in for winter. Check the attic and garage. - Winter: with lows near 43°F in Baton Rouge, check the attic, garage and pantry for droppings.
Mice or rats?
- 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. - Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized.
Sealing small gaps yourself.
- 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. - Sealant or mortar: cover the mesh so it stays put.
Cleaning up droppings safely.
- 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. - Wear rubber or plastic gloves.
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.
- 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? - Which gaps will you seal, and with what?
Ways to keep the cost down.
- Act early, before rodents spread to the attic. - Compare what each quote seals, not just the price. - Clear clutter so gaps are easy to reach. - Store food and pet food in sealed bins.
Rodents by the numbers.
For Baton Rouge homes, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. For Baton Rouge 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 Baton Rouge 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
- Number of trapping visits needed to reach zero.
- Mice versus rats; rats take longer and cost more.
- Sewer line inspection if rats are entering underground.
- Home size, stories, and roofline complexity.
- Age of the home and condition of the foundation.
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Whether sheds, garages or other outbuildings are included.
- Exterior bait stations and ongoing service frequency.

What's your biggest concern about rodent control costs?
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.

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.
