Mouse Exterminator Cost: Trapping and Exclusion

Most homeowners pay somewhere around $200 to $600 for a professional mouse exterminator to inspect, trap or bait, and make a few follow-up visits for a typical infestation. Exclusion work, sealing the gaps where mice get in, is what actually keeps them out, and it usually adds a few hundred dollars for minor sealing up to $1,500 or more for a whole-house job. Ongoing quarterly or monthly protection plans cost less per visit but add up over a year, and attic cleanup after a heavy infestation can be the most expensive item of all. Below are typical ranges for each service, what pushes the price up or down, and how to compare quotes.

What a Mouse Exterminator Does

A good rodent job has four parts, and quotes differ mainly in how many of them are included:

1. Inspection: Finding droppings, gnaw marks, runways, nests and, most importantly, entry points around the foundation, utility penetrations, garage doors, vents and roofline.
2. Population reduction: Snap traps, multi-catch traps and, where appropriate, tamper-resistant bait stations placed outdoors or in secure areas.
3. Exclusion: Sealing gaps with materials mice cannot chew, such as steel or copper mesh, metal flashing, hardware cloth, door sweeps and sealant.
4. Follow-up and sanitation: Return visits to check and reset traps, remove carcasses, and advise or perform cleanup of droppings and nesting material.

Mice can squeeze through a gap about the width of a pencil, roughly 1/4 inch, so exclusion is detailed work. If you are not sure whether you have mice or rats, check droppings: mouse droppings are about the size of a grain of rice, rat droppings closer to a raisin. Our guide to mice vs rats has more identification tips, and our pest control guide covers other household and garden pests.

Typical Mouse Exterminator Costs

Service	Typical range	What’s usually included
Inspection	Free to about $200	Whole-home check, entry point list, treatment plan; often credited toward service
One-time trapping or baiting	About $200–$600	Initial setup plus 2–4 follow-up visits over several weeks
Exclusion: minor sealing	About $300–$700	Sealing a handful of accessible gaps, door sweeps, vent screens
Exclusion: whole-house	About $800–$2,500+	Full perimeter, roofline, garage, utility penetrations; often with a warranty
Monthly service plan	About $40–$80 per month	Exterior bait station servicing, interior checks as needed
Quarterly service plan	About $100–$250 per visit	General pest plus rodent monitoring
Droppings cleanup and sanitizing	About $200–$600 for limited areas	Removal of droppings and nesting, disinfecting, in accessible spaces
Attic insulation removal and replacement	About $1,500–$5,000+	Contaminated insulation removal, sanitizing, new insulation

These are typical ranges for planning, not quotes. Prices vary by region and company, and many companies bundle inspection, trapping and exclusion into a single package price.

What Drives the Price

• Severity: A couple of mice in the kitchen is a small job. An established population across walls, attic and basement needs more traps, more visits and more cleanup.
• Home size and construction: Larger homes have more perimeter to inspect and seal. Older homes, stone foundations, crawl spaces and complex rooflines have more gaps.
• Access: Sealing at the roofline may need tall ladders or lifts. Finished basements limit access to the sill plate where many gaps hide.
• Exclusion scope: Spot sealing is far cheaper than a full exclusion package with a written warranty.
• Region: Prices tend to be higher in large metro areas.
• Contract type: One-time service costs more per visit; annual contracts lower the per-visit price but commit you for the year.
• Urgency: Same-day or weekend calls can carry a premium.

Trapping vs Baiting vs Exclusion

Trapping

Traps remove mice without poison and let the technician confirm results. Many pros prefer trapping inside the home because there is no risk of mice dying in walls from bait and causing odors. Trapping usually requires several follow-up visits to check and reset traps.

Baiting

Rodenticide bait in locked, tamper-resistant stations is mostly used outdoors around the foundation, or in secure indoor areas like garages. It can reduce larger populations, but poisoned mice can die in inaccessible spots, and bait poses risks to pets and wildlife that eat poisoned rodents. Ask which active ingredient is used and where stations will go, especially if you have pets or children.

Exclusion

Exclusion is the only part that stops new mice from coming in. A company that traps without sealing entry points will often be back next season. Look for quotes that list the specific gaps and the materials used, and ask whether the exclusion is warranted and for how long. Our guide to getting rid of mice in walls explains why entry points matter so much.

DIY vs Hiring a Pro

Homeowners can handle many small mouse problems with snap traps baited with peanut butter, set along walls where you see droppings, and some steel wool and sealant. DIY makes sense when:

• You have seen one or two mice and few droppings.
• You can find and reach the entry points.
• You are comfortable checking traps daily and disposing of mice.

Call a professional when you see droppings in multiple rooms, hear activity in walls or ceilings, find nests in the attic, cannot locate the entry points, or keep catching mice week after week. Our guide on how to get rid of mice and rats covers DIY methods in detail.

Example Scenarios

To show how the pieces add up, here are three common situations and the kind of service package each typically calls for. Actual quotes will vary.

A few mice in the kitchen of a newer home

The technician finds droppings under the sink and behind the stove, traced to a gap around the dishwasher drain line and a worn garage door seal. A one-time trapping service with two follow-ups, plus sealing those two spots and adding a door sweep, usually lands toward the lower end of the ranges above. Many homeowners could handle this one themselves.

Mice in the walls and attic of an older house

Scratching at night, droppings in the attic and multiple gaps at the sill plate, roof returns and utility lines. Expect a package that combines several weeks of trapping, exterior bait stations, and a whole-house exclusion with a warranty. This is where totals climb into the higher ranges, and where exclusion pays for itself by preventing repeat calls.

Heavy, long-term infestation

Nests through attic insulation, odor, and urine staining. Beyond trapping and exclusion, the insulation often needs to be removed, the space sanitized, and new insulation installed. Some pest control companies do this themselves; others refer it to insulation contractors. Get the cleanup quoted separately so you can compare it.

Pets, Kids and Bait Safety

If you have dogs, cats, or young children, tell the company up front. Ask them to rely on traps indoors, to use only locked, tamper-resistant bait stations anchored outside, and to note where every station is located. Ask for the product label for any bait used and keep it handy in case of accidental exposure. Some companies offer no-bait programs built entirely on trapping and exclusion; they can take a little longer but remove the secondary poisoning risk to pets, owls, hawks and other wildlife.

How to Compare Exterminator Quotes

1. Get two or three quotes after in-person inspections, not phone estimates.
2. Ask each company to list the entry points they found and which they will seal.
3. Confirm the number of follow-up visits included and what happens if mice persist.
4. Ask whether they use traps, bait or both, and where.
5. Read the warranty: what it covers, for how long, and whether it requires a service contract.
6. Check that the company holds the state pest control license required where you live and carries liability insurance.
7. Watch for pressure to sign long contracts on the first visit, or quotes that include only bait stations with no exclusion.

Cleanup and Health Precautions

Mouse droppings and urine can carry disease, including hantavirus from deer mice in some regions. Public health guidance is to avoid sweeping or vacuuming dry droppings, which can stir up particles. Instead, ventilate the area, wear gloves, spray droppings and nesting material with a disinfectant or a diluted bleach solution, let it soak, then wipe it up with paper towels and bag it. For heavy contamination in attics or crawl spaces, professional cleanup is worth the cost.

Keeping Mice Out Afterward

• Store pet food, birdseed and grass seed in metal or heavy plastic containers with tight lids.
• Keep firewood stacked off the ground and away from the house.
• Trim shrubs and ground covers back from the foundation.
• Install door sweeps on garage and exterior doors.
• Inspect each fall, when mice look for shelter, and reseal any new gaps.
• Keep garbage and recycling bins lidded, and rinse food containers before recycling them.
• Clean up fallen fruit, spilled birdseed and outdoor pet food bowls each evening, since these draw mice close to the house before they ever find a way inside.
