Roof Rat

Where they can be found: Roof rats tend to dominate coastal cities along waterways in warmer climates. That is why they are often found in the Greater Seattle area. Since they are nocturnal, they are often not seen during the day and are seen by homeowners during the night. They like to nest in higher areas like trees or attic spaces.

Where they can be found: Silverfish can be found in damp conditions like in basements, bathrooms or warehouses. In order to eliminate the problem, reducing humidity helps a lot. This is why they are often common in Seattle because of the humidity.
