Pest control in Bellevue is regulated by the Washington Department of Agriculture under RCW 17.21, with landlord duties under the Residential Landlord-Tenant Act (RCW 59.18).
Bellevue does not have a dedicated pest control ordinance; commercial pest control is regulated by the Washington State Department of Agriculture (WSDA) under RCW 17.21 (Washington Pesticide Application Act) and WAC 16-228. Commercial applicators must be licensed, maintain records of applications, and follow label directions precisely. Restricted-use pesticides require additional certification. Homeowners treating their own property generally do not need a license but must follow label directions and avoid drift onto neighboring properties. Landlords in Bellevue owe tenants habitable premises under the Washington Residential Landlord-Tenant Act (RCW 59.18.060), which includes keeping units free of insect and rodent infestations unless the tenant caused the problem. Bed bug infestations have specific disclosure and cost-allocation rules. Rats and rodent harborage complaints on private property may fall under Bellevue Code Compliance through general nuisance provisions; food service establishments are inspected by King County Public Health. Integrated pest management approaches using traps, exclusion, and targeted applications are encouraged. Pollinator-safe practices are recommended to protect bees and other beneficial species.
