Seeing a fast, furry animal in your yard or attic can make you wonder: is it a rat or a squirrel?
Many Washington homeowners struggle to distinguish between them, especially when the animal moves quickly or leaves similar damage. Both pests chew and build nests, and both can race through trees or across rooftops, but the risks differ.
In Olympia and Tacoma, rats often show up in crawl spaces and basements, while squirrels usually stick to trees and attics. Homeowners in Seattle and nearby coastal towns can encounter both pests.
If you know which pest you have, you can prevent damage to your home, wiring, and insulation before the problem worsens, or decide when to contact rodent control and exterminator services in Washington for help.
This guide explains the differences between rats and squirrels in Washington State, including how they look, what they do, the risks they pose, and next steps.
Key Takeaways:
- Rats and squirrels can look similar, but their tails, droppings, and nests are different.
- In Washington State, both do well in wooded and suburban areas where food is readily available.
- Rats pose a greater risk because they spread germs and damage homes.
- Professional rodent control can help protect homes in Olympia, Tacoma, and nearby areas all year.

What’s the Difference Between Rats and Squirrels in Washington State?
Rats and squirrels are both rodents that chew with strong front teeth called incisors, but they look and behave differently and live in different habitats.
In the Pacific Northwest, Norway rats and roof rats cause most rat problems. Gray squirrels and red squirrels are common tree squirrels in Washington and Oregon.
Rats prefer dark places such as burrows, basements, and crawl spaces. Squirrels stay active during the day and run along trees and power lines with bushy tails.
Rats can leave greasy rub marks on walls. Squirrels may chew into bird feeders and carry nesting material into attics.
Other animals, such as chipmunks, raccoons, and voles, can also be mistaken for rats or squirrels because they forage near homes and gardens.
Comparison Table: Rats vs. Squirrels
| Species | Appearance | Behavior | Habitat | Risks & Signs |
|---|---|---|---|---|
| Norway Rat (Brown Rat) | Large, stocky body with coarse brown or gray fur and short tail. | Nocturnal, prefers ground level; builds burrows near homes. | Crawl spaces, basements, under decks. | Chews wiring, greasy rub marks, capsule-shaped droppings. |
| Roof Rat | Slender, dark fur, long scaly tail, pointed nose. | Excellent climber; travels along roofs and power lines. | Attics, trees, garages, upper floors. | Scratching in ceilings, gnaw marks, small shiny droppings. |
| Gray Squirrel | Medium-sized, gray fur, long bushy tail. | Diurnal; agile climber, visits bird feeders. | Trees or attics, especially near wooded neighborhoods. | Chewed wood or insulation; larger rounded droppings. |
| Red Squirrel | Smaller, reddish fur with white belly. | Highly territorial; stores food for summer. | Wooded areas, sheds, occasionally attics. | Loud chatter; scattered nut shells near nests. |
| Flying Squirrel | Small brown fur, flattened tail, gliding membranes. | Nocturnal; glides silently between trees. | Forested areas or attics near woods. | Night activity, nesting in insulation, small rounded droppings. |

What Does a Rat Look Like in Washington State?
The Washington Department of Fish and Wildlife (WDFW) notes that North America’s rodent population includes many species adapted to the Pacific Northwest.
Washington’s rainy climate drives rats into homes for several reasons, including shelter and access to food. In Washington and Oregon, the most common are the Norway rat and the roof rat, also known as the black rat, both known for their chewing habits and their ability to live near people.
| Species | Appearance | Behavior | Habitat | Risks & Signs |
|---|---|---|---|---|
| Norway Rat (Brown Rat) | Large, heavy body with a blunt nose, small ears, short tail, and coarse brown or gray fur. | Poor climber but excellent burrower; primarily active at night. | Builds burrows under decks, in crawl spaces, basements, and near foundations. | Gnaws on electrical wiring, leaves greasy wall marks, and pellet-shaped droppings. |
| Roof Rat | Slender, lighter body with a pointed nose, large ears, long scaly tail, and dark brown or black fur. | Agile climber; travels along trees, roofs, and power lines. | Common in attics, rafters, trees, and upper levels of structures. | Scratching in ceilings, gnawing entry points, and shiny black droppings in hidden spaces. |
Some small rodents can leave similar droppings, so correct identification matters before you choose a control plan. If you suspect rats, we can inspect your home, remove them, and help prevent their return.
What Does a Squirrel Look Like in Washington State?
Squirrels are larger and more agile than rats, with bright eyes and distinctive bushy tails. According to the WDFW, Washington State is home to four native tree squirrel species and two introduced species, with occasional sightings of the California ground squirrel in certain areas.
The gray squirrel is the most common across Washington, while the smaller red squirrel is known for its chatter. In wooded suburbs around Olympia and Tacoma, you might also spot the flying squirrel, which glides between trees at night.
| Species | Appearance | Behavior | Nesting Habits | Notable Traits |
|---|---|---|---|---|
| Gray Squirrel | Medium-sized with gray fur and large bushy tails; common in urban and wooded areas. | Active during the day; agile climber often seen near bird feeders or rooftops. | Builds leafy nests high in trees but may enter attics or crawl spaces for warmth. | Most common tree squirrel in Washington State and Oregon. |
| Red Squirrel | Smaller with reddish fur and a white underbelly. | Energetic and noisy; highly territorial around food sources. | Prefers dense forests; may nest in sheds or garages. | Known for loud chatter and storing pine cones for summer. |
| Flying Squirrel | Small, soft brown fur with a flattened tail and gliding membrane. | Nocturnal; glides silently between trees while foraging. | Nests in tree cavities, attics, or wall voids near forested areas. | Only nocturnal tree squirrel species in the Pacific Northwest. |
Squirrel droppings are often rounder and a bit larger than rat droppings. You may find them near nesting spots. Squirrels stay active all year. They store acorns and other food to help them get through summer.
If squirrels nest in your home, do not seal the entry hole right away. Babies may still be inside. PCI Pest Control can safely remove the squirrels and seal entry points to prevent future problems.
Why Are Rats and Squirrels Often Confused in Washington State?
In the Pacific Northwest, rats and squirrels often live near people because they find plants, moisture, and easy food nearby, especially around bird feeders and garbage cans. Both can get into attics or walls and chew through many materials.
Their fur color and size can appear similar, especially in dim light. Fast movement across rooftops or fences can make it hard to tell a squirrel from a roof rat. Both species also force entry through small gaps, produce small droppings, and may use attic insulation as nesting material.
The Washington Department of Fish and Wildlife (WDFW) notes that rodents and small mammals such as voles, chipmunks, and raccoons readily adapt to North America’s temperate zones. This overlap in behavior and habitat often causes homeowners to mistake one species for another.
Whether you’re in Seattle, Tacoma, or Olympia, PCI Pest Control can help identify and remove these rodents before they cause serious infestation problems.
Which Is More Dangerous, Rats or Squirrels?
Rats typically cause more serious problems than squirrels and can spread diseases such as hantavirus through droppings, feces, urine, and nesting materials. They can also damage homes by chewing through walls, insulation, and electrical wiring, and they may carry fleas that spread to pets.
Squirrels rarely spread disease to people, but they can still damage attics and chew through wood and cables. Between the two, rats pose a higher health risk and greater risk of infestation in Washington homes.
How Do You Get Rid of Rats and Squirrels in Washington State?
To eliminate rats and squirrels in Washington State, implement a safety-focused, prevention-focused plan. These rodents remain active year-round. They often get in through rooflines, vents, crawl spaces, and damaged siding.
Steps for Removing Rats
Rats take more than one step to fix. You need to inspect, block entry points, install traps, and clean up.
Start by sealing entry points you find, including cracks and gaps around vents and the foundation. Remove clutter and secure food, such as pet food and trash, and keep garbage cans tightly closed to reduce opportunities for rats to stay.

FAQs
How can I quickly tell a rat from a squirrel in Washington State?
Look at the tail: rats have long, scaly tails, while squirrels have bushy tails. Rats move low to the ground at night, while you will typically see squirrels during the day, climbing trees.
Which is more likely to invade homes in Olympia or Tacoma?
Rats are more likely to enter basements and crawl spaces, especially Norway rats and roof rats. Squirrels, chipmunks, and voles primarily enter attics or gardens during the colder months or when trees are close to the roofline.
Does the weather in Washington State affect rat or squirrel activity?
Yes. Rainy seasons drive rats indoors to find dry shelter, while squirrels seek attic spaces in summer. Mild Pacific Northwest temperatures allow both to remain active year-round, increasing the need for preventive pest control.
