Mice

– See small droppings in cabinets or drawers.
– Hear scurrying at night in walls or attic.
– Find chew marks on boxes and wires.

Snap traps baited with peanut butter placed along walls and runways; seal all entry points after population reduction; tamper-resistant bait stations for ongoing perimeter control.

We set snap traps along walls and runways. Then we seal entry holes after we cut their numbers.

– Seal entry points — any gap a pencil can fit through can admit a mouse.

– Store all food including pet food in sealed containers.

– Keep kitchen surfaces clean and empty trash bins nightly.

– Place snap traps along walls and behind appliances where mice travel.

– Remove clutter and cardboard from garage and basement to eliminate nesting material.

– Seal any gap a pencil fits through.

– Store pet food and dry goods in metal bins.

– Keep basements dry and remove cardboard piles.

Nests in wall voids, kitchen cabinets, and insulated pipes; home range is small (10–30 feet from nest); enters through gaps as small as 6mm (roughly the diameter of a pencil). Mice breed quickly; one female can produce dozens of young a year. A small problem grows fast when food and shelter are easy to reach.

Mice are common in Portland, especially in fall. They enter old and new homes through small gaps.
