What Keeps Mice Out of Your House?

What keeps mice out of a house is sealing the gaps they use to get in, with materials they can't chew: steel wool plus sealant, metal mesh, hardware cloth, concrete and good door sweeps. A mouse can fit through a gap about the width of a pencil. Removing food and clutter helps, but scents like peppermint and ultrasonic plug-ins don't keep mice out for long. Silver Bullet Pest Control: 973-510-2585.

Where mice get into NJ homes

SpotWhat to look for
Pipes and gas linesGaps where lines enter the house, under sinks and at the meter
Garage doorsWorn bottom seals and gaps at the corners
Exterior doorsLight showing under the door; missing sweeps
Foundation and sill plateCracks and gaps where the house sits on the foundation
Dryer and exhaust ventsMissing or broken flaps
AC linesGaps around the line set going into the wall
Roofline and atticGaps at soffits and roof returns (mice climb)

What works

  • Steel wool or copper mesh plus sealant for small gaps around pipes and cables
  • Hardware cloth or metal mesh for vents and larger openings
  • Door sweeps and garage door seals rated for rodents
  • Concrete or mortar for foundation cracks
  • Storing food in sealed containers, including pet food and birdseed
  • Less clutter in basements, garages and against the outside of the house

What we see on these jobs

The three situations behind most of these calls in North Jersey:

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.

What doesn't work

  • Peppermint oil and dryer sheets: the scent fades fast and mice ignore it.
  • Ultrasonic plug-ins: mice get used to them, and sound doesn't pass through walls.
  • Spray foam alone: mice chew right through it.
  • Mothballs: not labeled for mice and unsafe to use that way.

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.

Frequently Asked Questions

What keeps mice out of a house permanently?

Sealing every gap with materials they can't chew, like steel wool with sealant, metal mesh and concrete.

How small of a hole can a mouse fit through?

About the width of a pencil.

Does peppermint oil keep mice away?

Not for long. The scent fades and mice ignore it.

Do ultrasonic repellers keep mice out?

No. Mice get used to them.

Can mice chew through spray foam?

Yes. Use steel wool or mesh with sealant instead.

When do mice come inside?

Mostly in fall as it gets cold, but they can come in any time of year.

Do you seal the entry points?

Yes. Sealing gaps with steel and the right materials is how we keep rodents from coming back.

What if I keep seeing mice after treatment?

Mice and rodent service includes 90 days of coverage with unlimited free service calls, so we come back.

Do you treat apartment buildings and restaurants?

Yes. We handle rodents in multi-family buildings and food businesses and can set up ongoing service.

How do I clean up droppings safely?

Air out the room, wear gloves, spray with disinfectant, wait five minutes, wipe with paper towels and bag them. Never sweep or vacuum dry droppings.

Do mice come back every fall?

Often, yes. As it gets cold, mice look for warm shelter, so fall is the busiest time. Sealing gaps before then helps a lot.

Can mice chew through walls?

They can chew through drywall, wood, plastic and foam. Steel, metal mesh and concrete stop them.

How much does mouse control cost?

It depends on the size of the home and how many entry points need sealing. Call or text 973-510-2585 for a free quote.

Is there a guarantee?

Our One-Time Mouse Service is 100% guaranteed.
