Maricopa County Vector Control investigates rodent complaints under ARS §36-602 and county nuisance rules. Property owners must eliminate harborage and active infestations. Arizona allows EPA-registered rodenticides, traps, and bait stations for consumer use.
Maricopa County addresses rats, roof rats, and other commensal rodents on two tracks. Arizona ARS §36-602 and county environmental health rules make property owners and occupants responsible for eliminating food sources, harborage, and active rodent populations on residential and commercial parcels. The Maricopa County Vector Control Division investigates complaints, conducts neighborhood surveys, and runs the long-running roof-rat education program for the Arcadia, central Phoenix, and east Valley outbreaks. City code-enforcement agencies handle abatement orders and liens for non-compliance inside cities; county Planning enforces in unincorporated areas. Arizona has not banned second-generation anticoagulants for consumer use, so homeowners may still buy snap traps, bait stations, and EPA-registered rodenticides at hardware stores.
Failure to comply with a Vector Control or city abatement notice is a civil violation with fines exceeding two thousand dollars per day plus reinspection and abatement costs liened against the property. Improper rodenticide use is separately enforceable.
