Bat Removal in Washington

What's Driving Bat Removal Demand in Washington

Washington's extensive bridge and highway infrastructure, built to cross the state's many rivers and the Puget Sound waterways, has created an unusual and well documented bat roosting habitat: expansion joints, box girders, and other structural gaps built into bridges along the I-5 corridor and elsewhere provide sheltered, temperature stable spaces that bat colonies use for both day roosting and, in some cases, maternity colonies, a pattern the Washington State Department of Transportation actively monitors and manages. That infrastructure based roosting is distinct from the cave and barn habitat that shapes bat removal work in most other states, and it means bat activity in Washington isn't confined to older buildings the way it typically is elsewhere, a colony can just as easily be living in a modern overpass as in a century old barn. For residential bat removal specifically, this broader roosting pattern means colonies displaced from bridge structures sometimes relocate to nearby homes, adding a state infrastructure dimension to what's usually a purely building focused problem.

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.
