Northeast Wisconsin's Most Common Winter Intruder

🐭 House Mice

House mice are the most common rodent problem in Northeast Wisconsin homes and businesses. A single pair can produce up to 60 offspring per year. They contaminate food, chew through wiring (a leading cause of house fires), and spread diseases including salmonella and hantavirus. Fast, thorough action is essential.

How to Identify

House Mice

Gray-brown fur, 2.5–3.5" body with a tail of equal length. Small eyes and ears. Pointed snout. Droppings are 1/4" rod-shaped with pointed ends. Mice can squeeze through gaps as small as a dime.

Signs of Infestation

What to Look For

Droppings in kitchen drawers, cabinets, and along baseboards. Gnaw marks on wood, wires, and food packaging. Greasy rub marks along walls where mice travel. Scratching or scurrying sounds in walls and ceilings at night. A musky odor in enclosed spaces.

Seasonal Activity

When to Watch Out

Mice are year-round pests but become a major indoor problem in fall (October–November) when they seek warmth and food. Indoor populations remain active throughout winter. Spring brings outdoor population growth as breeding accelerates.

Prevention Tips

How to Prevent House Mice

Seal all gaps and cracks larger than 1/4" — mice can squeeze through a dime-sized opening
Install door sweeps on exterior doors, including garage doors
Store food in sealed, hard-sided containers — mice chew through cardboard and plastic bags
Keep firewood elevated and at least 20 feet from the structure
Trim vegetation away from the foundation — mice use branches as highways to your roof
Our Treatment

Professional Treatment Process

01

Full Property Inspection

We locate all active entry points, travel paths, nesting sites, and the extent of the infestation. Every gap, crack, and penetration is documented.

02

Entry Point Sealing

We seal gaps with rodent-proof materials — steel wool, hardware cloth, and professional-grade sealants. Physical exclusion is the most effective long-term solution.

03

Tamper-Resistant Bait Stations

Locked, child- and pet-safe bait stations are placed in key activity zones inside and outside the structure to eliminate the existing population.

04

Ongoing Monitoring

Regular service visits check stations, track activity, and adjust strategy as needed. Our between-visit guarantee means if mice return, we come back at no charge.
