Protect Your Home and Business From Rodents.

Rodents Found In Washington State

Did you know Seattle is one of America’s most rat-infested cities, thanks to rats’ ability to reproduce as many as 15,000 offspring from a single pair of rats each year? Rodents pose a huge threat to Puget Sound homes and businesses, from the dangerous diseases they bring with them to the hazard they can pose when they nest in your walls and find the food stored in your pantry.

What Do House Mice Look Like?

The common house mouse is a rodent with small, beady eyes and ears that are large in proportion to the rest of its body. An adult mouse can weigh up to 1/2 an ounce and can be as long as 5-1/2 to 7-1/2 inches in length, including a tail that is 3 to 4 inches long. Mice range in color from deep gray to light brown.

Where Can I Find House Mice?

House mice commonly dwell in undisturbed storage areas, shoe boxes, and closets. Common signs that indicate a house mouse infestation include tracks, sightings, droppings, and chewed-on furniture or other materials. It may also be possible to smell if mice are present in a home by the musty odors they produce.

How Do House Mice Behave?

House mice can squeeze through tiny spaces that are as small as 1/4 of an inch wide. They are excellent climbers and jumpers. In fact, mice can jump 12 inches, reaching shelving and other above-ground areas. Mice also have powerful senses of smell, touch, hearing, and taste. They feed as frequently as 15 to 20 times per day, eating any available food but preferring oats, corn, and wheat.

What Do Norway Rats Look Like?

A Norway rat is red or brown in color with a white underbelly. It has coarse fur, small ears, and a tail that is scaled and no longer than the body and head combined. Norway rats can be as big as 10 to 12 inches. They are also commonly known as street rats or sewer rats.

Where Can I Find Norway Rats? 

Norway rats are commonly found in fields, woodpiles, farms, and buildings. If they have invaded a building, they prefer living on the ground level or in the basement. Nests are made from shreds of fabric and paper.

How Do Norway Rats Behave?

Although Norway rats prefer grains, fruit, nuts, and meat, they will eat just about anything. Water intake varies based on what food is available. While they use ultrasonic communication, some of their noises, including bruxing or squeaking, can be heard by the human ear.

Roof rats’ fur is smooth and usually gray-black or brown with black or white-gray underbelly fur. These rats are typically 16 inches in length from the tips of their noses to the ends of their tails—which are hairless, scaly, and long. Roof rats are also commonly called ship rats or black rats and are notorious for carrying plague and other communicable diseases. Mites and fleas are frequently found in their fur. They are also known to cause considerable damage to stored food and other property.

Where Can I Find Roof Rats?

Roof rats can be found in garages, sheds, and other outbuildings. When they venture indoors, they can be found in ceilings, underneath flooring, and within walls. These rodents are known for their excellent climbing abilities, which is where the name “roof rat” derives from. They often climb to the tops of buildings and make their homes within roofing structures and attic spaces.

How Do Roof Rats Behave?

These rodents have excellent senses of hearing, taste, touch, and smell, although their sense of sight is quite poor. At three months of age, a roof rat has reached maturity and is capable of reproducing. Preferred foods include berries, fruit, vegetables, pet foods, nuts, grains, decomposing food, snails, and slugs.
