Eastern Gray Squirrels in the Pacific Northwest
Initially introduced to the Pacific Northwest in the early 1900s, the Eastern gray squirrel has successfully established itself in several urban areas. This species thrives primarily in urban settings where they have adapted well to the presence of humans. Their ability to flourish in suburban and urban environments underscores their adaptability and resilience, making them a common sight in these areas despite being non-native.
Eastern Gray Squirrel Habitat
Eastern gray squirrels employ two main types of nests for shelter: dens within tree cavities and leaf nests known as dreys. Leaf nests are particularly prevalent during the summer months, positioned strategically in the top fork of a tree or the crotch of a limb. Although these nests are typically constructed within a day, squirrels often build multiple nests to ensure safety and comfort through various seasons.
Eastern Gray Squirrel Behaviors, Threats, or Dangers
Eastern gray squirrels do not hibernate, relying on their nests for warmth and protection during the winter months. Their presence can become problematic when they invade human dwellings, gnawing on electrical wiring, which can cause significant damage, including electrical shorts and potential fires. They pose health risks as carriers of bacterial diseases, which can be transmitted to humans through bites or indirect contact with their feces. Evidence of an Eastern gray squirrel infestation includes unusual noises from attics, damaged bird feeders, and chewed electrical installations, necessitating careful management to prevent property damage and health hazards.
If you are having an issue with eastern gray squirrels, it is best to consult a professional wildlife control company for removal.
