The 3 Most Common Rodents in Oregon

Rodents are a common problem for homeowners in Oregon, and knowing how to identify the specific type of rodent you’re dealing with is key to effective pest control. Keep reading as we discuss house mice, Norway rats, and roof rats – Oregon’s three most common rodents. We’ll describe their physical characteristics, habitats, and behaviors, as well as the potential health risks they pose to humans and pets. By understanding these common rodents, you’ll be better equipped to identify and address rodent infestations in your home.

House Mice

The house mouse, the smallest subfamily member in Oregon, is found in 30 of the state’s 36 counties. They have large, membranous ears, a long scaly tail, and short, harsh pelage that ranges from grayish brown to nearly black dorsally and lighter brown or buffy ventrally. They are often active at night and tend to stay hidden behind or beneath objects during the day in barns, warehouses, and other buildings. House mice appear in various colors, including albino and spotted.

Norway Rats

The Norway rat, the largest subfamily member in Oregon, is found worldwide. It is primarily found in most of the counties west of the Cascade Range and some counties along the Columbia River east of the Cascade Range. This heavy-bodied rat has a course, grizzled brownish or rusty gray pelage dorsally and dirty white to yellowish gray ventrally. It has a scantily haired, scaly tail shorter than the length of the head and body and lightly furred, membranous ears. Norway rats are nearly always found near human activity, occupying houses, warehouses, stores, sewers, and other structures that provide shelter and a nearby food source.

Roof Rats

Roof rats, also known as Black rats, are smaller than Norway rats and have longer tails. They have a refined sense of hearing and prefer to eat small amounts of various foods, especially fruits, and nuts. Roof rats are arboreal and originally favored trees but have adapted to human homes, climbing power lines and burrowing underground. They carry a variety of diseases, including bubonic plague, typhus, and toxoplasmosis, and can transmit them through droppings, urine, bites, and fleas and mites in their fur. They can mate year-round and average around eight young per litter. Roof rats do not handle cold weather well and are less successful than Norway rats at dominating an area.

Portland Rodent Prevention Tips

Rodent prevention is essential to protect your home or business from damage and health hazards. The following are some practical tips to help prevent rodent infestations. First, ensure proper sanitation by regularly cleaning and removing food debris, which will help eliminate the rodents’ food sources. Secondly, seal all entry points to prevent rodents from entering buildings. Inspect doors, windows, walls, and foundations for any holes or gaps that can provide access. Finally, regular inspections are necessary to detect and prevent rodent infestations before they become severe.
