Mice in the Attic: Signs, Causes & How to Get Rid of Them

Mice in the attic usually show up as light scratching or scurrying in the ceiling at night, small droppings in insulation, nesting material and chewed wires or boxes. They get up there by climbing inside walls from the basement or by entering gaps at the roofline. Getting rid of them takes trapping plus sealing the gaps they use, both inside and outside. Silver Bullet Pest Control: 973-510-2585.

How mice get up there

Mice climb well. Many get into the basement or garage first, then climb inside wall cavities, along pipes and wires, all the way to the attic. Others climb the outside of the house and get in through gaps at soffits, roof returns, gable vents or where the siding meets the roof. Older North Jersey homes with balloon framing (open wall cavities from basement to attic) make it especially easy.

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.

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 it matters

  • Mice chew wiring, which is a fire risk
  • Droppings and urine contaminate insulation
  • Nesting packs down insulation and makes it less effective
  • Stored boxes, holiday decorations and clothing get damaged

Getting rid of them

We trap the mice in the attic and the levels below, find how they're getting up (inside walls or from the roofline), and seal those gaps with steel and the right materials. Our One-Time Mouse Service is 100% guaranteed, and mice and rodent service includes 90 days of coverage with unlimited free service calls. See mice and rat service and what keeps mice out.

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

How do I know if I have mice in the attic?

Scratching at night, small droppings in insulation, nesting and chewed items.

How do mice get into the attic?

By climbing inside walls from below or through gaps at the roofline.

Is it mice or squirrels in my attic?

Mice are active at night; squirrels in early morning and late afternoon.

Can mice in the attic chew wires?

Yes, which is a fire risk.

Should I replace insulation after mice?

If it's heavily soiled, it may need to be removed and replaced after the mice are gone.

Do mice leave the attic in summer?

Not necessarily. They stay if they have shelter and food.

Is rodent service safe for kids and pets?

Yes. Traps and bait stations are placed where kids and pets can't reach them.

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.

Do you remove dead mice?

Yes. Traps are checked and removed as part of service.

Is there a guarantee?

Our One-Time Mouse Service is 100% guaranteed.
