Squirrel Removal in Washington

What's Driving Squirrel Removal Demand in Washington

Washington's squirrel story carries a real ecological twist most states don't have: introduced eastern gray squirrels now dominate Seattle area urban and suburban neighborhoods, having displaced the native western gray squirrel, which the state now lists as threatened and largely confines to more rural oak woodland habitat well outside the dense urban core. That means the squirrel actually entering attics and causing nuisance calls across most of Washington's populated areas is an introduced species competing successfully against a native one the state is actively working to protect elsewhere, a genuinely different backdrop than the single native species story found in most states. Washington's damp climate also softens roofline wood and siding over time in ways that create easier entry points than a drier climate would, giving the state's dominant introduced squirrel species both an ecological advantage over its native competitor and a practical advantage getting into homes that have sat through years of Pacific Northwest moisture.

Licensing in Washington: Washington regulates structural pest work through the Washington State Department of Agriculture (WSDA), which issues Commercial Applicator pesticide licenses covering the actual application of pesticides in and around structures; both the individual applicator and the business itself must be licensed, and applicators must pass a Laws and Safety exam plus the relevant category exam. Inspecting a building for termites, carpenter ants, wood boring beetles, and wood rot for a real estate transaction requires a separate credential, a Structural Pest Inspector (SPI) license, which is only valid for issuing a complete wood destroying organism report if the inspector works for a business that also holds an SPI company license. Both license types require recertification every five years. Removing nuisance wildlife such as raccoons or squirrels for a fee is licensed through an entirely different state agency: the Washington Department of Fish and Wildlife certifies Wildlife Control Operators, who must pass a trapper education exam and a WCO certification course, with permits valid for three years.
