House mice are the most common indoor rodent in the country, and the most commonly underestimated. A female can produce five to ten litters a year, so a small problem noticed in autumn becomes a substantial one by late winter.

Mice need a gap of only about a quarter of an inch — roughly the diameter of a pencil. That single fact explains why exclusion is difficult to do well and why most DIY attempts end in a recurring problem rather than a resolved one.

Signs You Have Mice

Droppings

Small, dark, rice-grain-shaped droppings concentrated along walls, in cabinets and behind appliances. Fresh droppings are dark and soft; older ones are grey and crumble.

Gnaw marks

Mice gnaw constantly to manage continuously growing incisors. Look for damage to food packaging, cardboard and — most seriously — wiring insulation.

Nesting material

Shredded paper, fabric and insulation packed into hidden voids: behind appliances, in drawers, inside wall cavities and stored boxes.

Night-time sounds

Scratching or light scurrying in walls and ceilings after dark, when mice are most active.

Smell

An established infestation produces a distinct musty ammonia odour from urine, usually strongest near nesting sites.

How Mice Are Treated Professionally

Inspection

Droppings and gnaw marks are traced to nesting areas and travel routes, and the structure is surveyed for the gaps being used.

Trapping

Multiple snap traps placed perpendicular to walls along runways. Mice are curious and investigate new objects readily — unlike rats — so trapping usually works quickly.

Exclusion

Every gap of a quarter inch or larger is sealed with steel wool and sealant, hardware cloth or sheet metal. Expanding foam alone is not sufficient; mice chew straight through it.

Follow-up

Traps are monitored until activity ceases, and sanitation of contaminated areas is completed.

What mouse treatment costs

$150–$500

for treatment and sealing

What moves the price:

How much exclusion work the structure requires
Number of follow-up visits
Whether contaminated insulation needs removal
Property size and construction type

These are typical national ranges, not quotes. Pricing depends on your property and the severity of the problem.

DIY Mouse Control — What Works

Trapping mice is genuinely achievable yourself. Use more traps than seem necessary, place them against walls with the trigger facing the wall, and bait sparingly — a smear of peanut butter beats a large bait that can be stolen cleanly.

Sealing is the part that usually gets skipped, and it is the part that decides whether they come back. Steel wool packed into gaps and sealed over is effective; foam or caulk alone is not, because mice chew through both.

Common questions

How much does a mouse exterminator cost?

Typically $150–$500 including sealing work. Trapping alone sits at the lower end; extensive exclusion or insulation replacement pushes higher.

How many mice is a typical infestation?

Seeing one mouse during the day often indicates a larger population, since mice are normally nocturnal and daytime activity suggests competition for space and food.

Do ultrasonic repellers work on mice?

Independent testing has consistently found little to no sustained effect. Mice habituate quickly to the sound, and the devices do not penetrate walls where mice actually travel.

How do I stop mice coming back?

Seal every gap of a quarter inch or larger, store food in sealed containers, and address exterior harbourage — woodpiles and dense vegetation against the foundation. Sealing is the step that lasts.
