Where Are the Mice Coming From?

Mice usually come from outside through small gaps around pipes and utility lines, under garage and exterior doors, through foundation cracks and vents, and sometimes from the roofline. In attached homes and apartments they can also come from next door. To find the spot, follow the droppings, look for gnaw and grease marks near gaps, and check where pipes enter the house. Silver Bullet Pest Control: 973-510-2585.

How to track them down

  1. Map the droppings. The heaviest spots are usually close to where mice enter or nest.
  2. Check under sinks. Gaps where pipes go through the wall or floor are common entry points.
  3. Look at the garage door corners and bottom seal; look for light showing.
  4. Walk the foundation outside, looking for gaps at the sill, around pipes, AC lines, dryer vents and the gas meter.
  5. Look for grease marks along walls and around holes, where mice rub as they pass.
  6. Check the basement where the walls meet the ceiling (the sill plate).

Mice

Mouse Treatment Inside the Home

  • Small droppings in drawers and cabinets
  • Chewed food packaging
  • Scratching in walls at night

Our One-Time Mouse Service is 100% guaranteed, and mice and rodent service includes 90 days of coverage with unlimited free service calls in that time.

Rat droppings found during a rodent inspection
Rats

Rats Around the House

  • Bigger, capsule-shaped droppings
  • Burrows along the foundation
  • Gnawing on wood, plastic or wires

Rats are wary and harder to trap than mice. The lasting fix is finding the burrows and gaps they use and closing them.

Sealing the Way In

  • Gaps around pipes and gas lines
  • Garage door seals
  • Foundation cracks and vents

Trapping handles the rodents inside. Sealing the gaps with steel and the right materials is what stops the next ones.

Why they come in

Mice move in for warmth, shelter and food. Fall is the busiest time in New Jersey, but construction nearby, demolition or a neighbor's cleanup can push mice into your home any time of year. Pet food, birdseed and pantry goods give them a reason to stay.

Sealing it for good

We find every entry point, seal them with steel and the right materials, and trap the mice inside. Our One-Time Mouse Service is 100% guaranteed, and mice and rodent service includes 90 days of coverage with unlimited free service calls. See rodent-proofing, what keeps mice out and signs of mice.

Simple ways to prevent it

🧱

Seal small gaps

Close gaps around pipes, cables and vents with steel wool plus sealant or metal mesh. Foam alone gets chewed through.

πŸšͺ

Fix door sweeps

Garage and basement doors need tight bottom seals. A gap you can slide a pencil under lets mice in.

πŸ₯«

Store food sealed

Keep cereal, rice, pet food and birdseed in glass, metal or hard plastic.

πŸ‚

Clear the perimeter

Keep firewood, leaf piles and dense shrubs away from the foundation.
