How do I know if I have mice or rats?

Mice droppings are small (3 to 6mm), dark, and pointed. Rat droppings are much larger (12 to 20mm). Mice gnaw marks are small and irregular; rat gnaw marks are larger with incisor ridges. Mice are smaller (15 to 20g) and more common in homes. Rats are larger (150 to 500g) and more often in basements, garages, and commercial areas.

Is rodenticide (poison) safe to use inside my home?

We strongly prefer snap traps over interior rodenticide because poisoned mice die inside walls, causing odor problems. Rodenticide is used in exterior, tamper-resistant stations only. Children and pets cannot access the bait in these stations.

How many mice do I likely have?

If you see one mouse, assume there are many more. Mice are nocturnal and avoid humans, a daytime sighting or frequent evidence means a significant population. Our technician will assess activity levels through feces quantity, gnaw marks, and trap placement.

How long does exclusion take?

A thorough exclusion of a typical home takes 2 to 4 hours. We seal all identified entry points and provide a written report. Combined with trapping, exclusion eliminates the active infestation and permanently prevents reentry.

Mice Control

Eliminate mice and seal every entry point they use

Mice can squeeze through a gap the size of a dime, contaminate 10 times more food than they eat, and gnaw through electrical wiring, causing house fires. A single pair can produce up to 60 offspring annually. Our mice control program combines snap trapping, exclusion sealing, and sanitation to eliminate active infestations and prevent all future entry.

Our Mice Control Treatment Methods

We select the most effective approach based on your specific infestation, property, and family situation.

Snap Trap Program

High-efficiency snap traps placed in harborage areas, along travel paths, and in wall voids. The safest and most effective trapping method, no poison in living spaces.

Full Exclusion Service

Every gap, crack, and opening mice use to enter is identified and sealed using steel wool, hardware cloth, and caulk (mice chew through foam on its own). This is the only permanent solution.

Exterior Bait Station Program

Tamper-resistant rodenticide stations placed around the exterior foundation intercept mice before they enter the structure. Child and pet safe design.

Sanitation Consultation

We identify conditions attracting mice, food storage issues, clutter, vegetation contact, and provide a written remediation guide.

How mice get in, and where traps go

UC IPM's house mouse guide puts numbers on the two things that decide whether mouse control works: how small a gap they use, and how close to the nest they stay.

Mice squeeze under gaps 1/4 inch tall and through openings 3/8 inch wide, so every gap larger than 1/4 inch needs sealing.
Seal with wire screen or coarse steel wool. Plastic screening, rubber, vinyl, expanding foam and wood can be chewed through, and steel wool scouring pads make good temporary plugs but may rust.
A female can have 5 to 10 litters a year of about 5 or 6 pups each.
Mice seldom travel more than 30 feet from their nest and food, so traps go close to walls, where mice run straight over the trigger, and no more than about 10 feet apart where mice are active.
Rodenticide used inside often means mice dying inside the structure. Bait belongs in tamper-proof stations out of reach of children, pets and wildlife.
