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
Attic and Crawlspace Cleanup and Sanitation
$500–$3,000, higher if insulation is replaced
Scent trails attract new rodents. Cleanup helps the sealing hold. Deodorizing and sealing a Madison attic makes it less inviting to the mice outside looking for a way in.
- Time
- Half day to two days
- Best for
- Heavy contamination; odor, urine-soaked insulation, nesting
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
Snap traps remain the workhorse for rodents inside Madison homes because a caught rodent is proof, not a guess. A Madison pro sets many traps along walls and runways, then returns to check, reset, and remove.

Which rodents live around Madison.
They're small, curious and breed quickly. Norway rats are the other usual suspect. They burrow along foundations and enter low. House mice are the most common rodent in Madison homes.
This is what a proper seal looks like: metal mesh fastened with screws and sealed at the edges. Foam or caulk on its own gets chewed through.When they move in.
Check for gaps before then. Spring is breeding season. Small problems grow fast.
How they get into houses here.
Rodents use gaps around utility lines, dryer vents and window wells. Check where pipes and cables enter. Look at the dryer vent flap. Window wells need covers or screens. Homes from Madison out to Janesville and Beloit share the same weak spots, so the checklist below works across the area. Plenty of homes in Madison have basements.
A year of rodents in Madison.
- Fall: mice move indoors as nights cool. Seal gaps in September. - Winter: with lows near 11°F in Madison, check the attic, garage and pantry for droppings. - Spring: breeding season. Act on any sign quickly. - Summer: with highs around 82°F in Madison, 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.)
Ways to keep the cost down.
- Clear clutter so gaps are easy to reach. - Store food and pet food in sealed bins. - Trim branches back from the roof. - Act early, before rodents spread to the attic. - Compare what each quote seals, not just the price.
Rodents by the numbers.
Across Madison, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. Across Madison, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Across Madison, 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.
What affects the price
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Sewer line inspection if rats are entering underground.
- Attic access and how much insulation is contaminated.
- Exterior bait stations and ongoing service frequency.
- Materials used for sealing: mesh, sheet metal, mortar.
- Mice versus rats; rats take longer and cost more.
- Number of entry points found during inspection.
- Age of the home and condition of the foundation.

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
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.

- Cover dryer and exhaust vents with metal louvered covers.
- Clean up pet waste and do not leave bowls out overnight.
- Keep garbage in lidded cans and pick up fallen fruit.

Questions people ask
Does home size change the price?
Bigger houses have more walls and roofline to seal. Attics and crawl spaces add time too. Yes.
Why is rodent-proofing so expensive?
Every gap needs metal mesh or sheet metal, then a seal. A typical house has dozens of small openings. It's careful, slow work.
Is a quarterly rodent plan worth it?
Homes near fields or water benefit most. For a one-time issue, a single sealing job is often enough. It can be, after repeat problems.
How much does rodent control cost in Madison?
Most full jobs in Madison run a few hundred to about $1,500. Attic cleanup costs extra.
What is rodent-proofing and why does it cost so much?
A mouse fits through a dime-sized gap, so it's slow work. It's also the part that keeps them out. It means sealing every gap with metal mesh and sealant.
How do I know if I have mice or rats?
Mouse droppings are about the size of a rice grain. Rats also chew larger holes and sound heavier at night. Check the droppings.
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.
