Norway rats, also known as brown rats, are one of the most destructive and invasive rodents in Seattle and King County. Unlike roof rats that nest above ground, Norway rats burrow deep in soil, crawl spaces, under concrete slabs, and beneath foundations. These strong diggers cause structural damage, plumbing issues, and health risks for both homeowners and businesses.
At AMPM Exterminators, we provide professional Norway rat extermination services throughout Seattle and Eastside cities, including Sammamish, Issaquah, Kirkland, Redmond, and Bellevue.
How to Identify Norway Rats
- Appearance – Large, stocky body with a blunt nose, small ears, and short tail (shorter than head + body).
- Habitat – Burrows in soil, under homes, and near sewers or foundations.
- Droppings – Large, capsule-shaped pellets found near burrow entrances.
- Activity – Night-active, often leaving dirt mounds and gnawed openings near structures.
Why Norway Rats Are Dangerous
- Structural Damage – Burrows weaken soil, foundations, and concrete slabs.
- Plumbing Issues – Frequently invade sewer lines, causing backups and leaks.
- Health Risks – Carriers of salmonella, leptospirosis, and other dangerous diseases.
- Rapid Infestation Growth – Breeding up to 7 litters per year, colonies expand quickly.
If you live in Seattle or Eastside neighborhoods like Sammamish, Issaquah, or Bellevue, Norway rats can spread rapidly through crawl spaces, yards, and commercial properties.
