Does Rain Bring Out Rats?

Yes. Heavy rain floods rat burrows and sewer lines, which forces rats to move to higher, drier ground, often into basements, garages, crawl spaces and wall voids. That's why many North Jersey homeowners see more rats, and hear more scratching, after big storms. Sealing entry points and keeping drains covered helps keep them out. Silver Bullet Pest Control: 973-510-2585.

Why rain moves rats

Norway rats, the most common rat in New Jersey, live in burrows in the ground and in sewers. When heavy rain floods those burrows and sewers, rats have to leave. They look for the nearest dry shelter with food, and a house with a gap at the foundation or an open garage is an easy choice. After the water goes down, some go back; others stay where they found food.

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.

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 to do before and after storms

  • Seal gaps around pipes, the foundation and garage doors before storm season
  • Keep floor drains covered and toilet lids down
  • Don't leave pet food or birdseed in the garage
  • After a storm, check the foundation, under the deck and the yard for new burrows
  • Listen for scratching in walls or ceilings at night

If rats got in

A rat inside the living space is an emergency for most families. We answer 24/7 and can send a tech at any hour; arrival depends on your location. See emergency rat and mouse service, rat exterminator and what keeps rats away.

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

Does rain bring out rats?

Yes. Flooded burrows and sewers push rats to drier places, including homes.

Why do I see more rats after a storm?

They've been flushed out of burrows and sewers.

Can rats come up through the toilet?

It's rare, but rats can swim through sewer lines. Keep the lid down.

Do rats come inside in the rain?

They look for dry shelter, and a house with gaps is an easy choice.

Will rats leave after the rain stops?

Some return to burrows; others stay if they find food and shelter.

How do I keep rats out during storms?

Seal entry points, cover drains and remove food from garages.

Do you remove dead mice?

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

Do ultrasonic repellers work on mice?

Studies show little lasting effect. Mice get used to the sound, and they don't seal any gaps.

What attracts mice to a house?

Warmth, shelter, and food like pet food, birdseed, crumbs and pantry goods.

How do mice get into a house?

Through gaps around pipes and cables, worn garage door seals, gaps under doors, foundation cracks and vents. A mouse fits through a gap about the width of a pencil.

Are mice and rats dangerous?

They contaminate food and surfaces with droppings and urine, can spread disease and chew wiring. That's why they shouldn't be ignored.

How long does it take to get rid of mice?

Most homes see activity drop within a couple of weeks once traps are in place and entry points are sealed. Rodent service includes 90 days of coverage.

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 come at night for a rat in the house?

Yes. We answer 24/7 and can send a tech at any hour.
