Public Health Seattle King County's Zoonotic Disease Program responds to rodent complaints in Seattle. Property owners must abate infestations under SMC 10.22 nuisance code; food businesses face additional inspection consequences.
Seattle's combination of mild winters, dense composting programs, and abundant food sources sustains a substantial Norway rat population. PHSKC's Zoonotic Disease Program tracks complaints, provides abatement guidance, and works with property owners. SMC 10.22 nuisance code requires property owners to maintain premises free of vermin harborage; persistent infestations are abatable nuisances. Seattle Public Utilities (SPU) runs a residential rat program offering inspections and recommendations. Restaurants with rodent evidence face PHSKC priority violations, possible placard downgrade, and closure if severe. Bait stations must be tamper-resistant and labeled per WSDA rules. Bird feeders, dropped pet food, and unsealed compost are leading attractants.
Failure to abate rat harborage: $250 to $1,000 under SMC 10.22 plus daily continuing fines. Restaurant infestation: PHSKC suspension. Improper bait stations: WSDA pesticide violations.
