Mice Exterminator Cost: What One Infestation Actually Runs

A typical mouse job totals $250–$600 in 2026, covering inspection, trapping, one or two follow-ups, and minor sealing of the obvious holes. Heavy infestations with full exclusion work run $600–$1,200. Expect two to four weeks of trapping to clear an established group, not a single visit. Prices vary by region, house construction, and company.

What the money actually buys

Why it takes weeks

Mice are neophobic — new objects in their territory get avoided for days. Traps set on a Monday often sit untouched while the animals work out whether the peanut butter on a spring-loaded bar is a problem. Meanwhile, the population inside the walls includes juveniles that were in the nest at the first visit and were not yet foraging. A single visit catches the bold adults and leaves the rest. Two to four weeks of trapping, with traps checked and repositioned, is the realistic timeline for an established indoor population. Anyone promising a one-visit cure is selling a service they cannot deliver, or defining “cure” as “we came out.”

DIY, judged fairly

Snap traps cost cents apiece and they work. This is one of the few pest categories where a homeowner can genuinely solve the problem alone. Where DIY succeeds:

• Traps placed along walls, perpendicular to the wall line, with the trigger end against the baseboard — mice travel with their whiskers touching vertical surfaces, not across open floor
• Enough traps. Six traps catch more than two; a dozen is not excessive for a kitchen and pantry
• Bait that is actually attractive: peanut butter, a dab of nutella, a piece of slim jim, or nesting material like cotton
• Patience past day three, which is when most people quit

Where DIY loses: finding and sealing the entry points. That is the part that requires a ladder, a crawlspace, a flashlight, and an hour of hunting gaps — and it is the part that determines whether you do this again next fall. Scale is the other factor. Two mice and a dozen mice are different projects.

Mice or rats?

The signs are distinguishable and the pricing differs, so look before you buy.

• Droppings. Mouse droppings are rice-grain sized, pointed at both ends, roughly a quarter inch. Rat droppings are larger, blunt-ended, and capsule-shaped, commonly a half inch or more.
• Gnaw marks. Mice leave small, fine, parallel tooth marks. Rats leave wider, coarser gouges.
• Rubs. Rats create dark grease smears along the paths they use repeatedly; mice do too, but the smears are smaller and less obvious.
• Sounds and smell. Scratching in walls is common to both; a musky odor is more typical of rats in a confined space.

Health and cleanup, without the panic

Mice carry and can transmit disease, and the cleanup is where most of the risk sits — not in the occasional sighting. Handle droppings with wet methods: spray the area with a disinfectant or a diluted bleach solution, let it sit, then wipe up with paper towels and dispose in a sealed bag. Never dry-sweep or vacuum droppings with an ordinary vacuum; that aerosolizes dust and, in the Southwest, hantavirus is a documented concern with deer mouse droppings. Wear gloves, work in ventilated spaces, and consider respiratory protection for attic work. Vacuuming with a HEPA-equipped machine is the better option when volume is high.

Store food — including pet food and birdseed — in hard containers with tight lids. Birdseed in a garage bag is a rodent feeder. Keep the pantry floor clean and reduce accessible water sources: fix drips, empty pet bowls overnight in active areas.

When it is the landlord’s problem

In rentals, structural pest control — rodents entering through building defects — is generally the property owner’s responsibility, though state and local rules vary and leases can shift some duties. Report the problem in writing, keep a copy, and document dates. See the renter’s guide for how the obligations usually split, and note that a landlord who says “call an exterminator” without more may still owe for structural repairs and exclusion work.

Before booking

• Does the price include follow-up visits, and how many?
• Is exclusion work included, quoted separately, or not offered at all?
• What is the guarantee period, and what counts as a return?
• Are traps checked by staff or left for you to monitor?

Rodenticide use follows product labels and state restrictions, and indoor poison use carries real secondary-exposure risk for pets and children — which is a good reason most of the indoor work is trapping. Keep it simple: trap aggressively, seal the gaps, and expect a few weeks of work rather than a single appointment.
