How to Spot a Mice Infestation Before It’s Too Late

Why early matters

A female house mouse can have a litter every three weeks or so, and the young can breed within a couple of months. One or two mice in October can be a real infestation by the holidays. Mice also contaminate everything they walk on with urine and droppings, chew wiring, and nest in insulation. Catching it early means fewer mice, less cleanup and a smaller, cheaper job.

Doing it yourself often stalls: a few traps catch a few mice, but the gaps they came through stay open. That's why our service combines trapping with sealing the entry points. Mice and rodent service includes 90 days of coverage with unlimited free service calls, and our One-Time Mouse Service is 100% guaranteed.

Where mice get into North Jersey homes

• Gaps around gas, water and cable lines where they enter the house
• Garage doors with worn bottom seals
• Gaps under exterior doors and around basement windows
• Cracks in old foundations and sill plates
• Dryer vents and AC line sets
• Shared walls and pipe chases in two- and three-family houses

A mouse can squeeze through a gap about the width of a pencil. See rodent-proofing for how we seal them.

DIY or professional?

Snap traps along walls can catch a few mice, and that's fine for a single mouse in a garage. If you're finding droppings in more than one room, hearing activity every night, or still catching mice after two weeks, the gaps are still open. A professional finds the entry points you can't see, sets traps where mice actually travel and seals the house so it stays mouse-free.
