Orange County HCA Vector Control District compels property owners to eliminate rat and mouse harborage, with mandatory abatement orders when infestations threaten neighbors or public health countywide.
OC Vector Control District, an independent special district covering all 34 cities and unincorporated areas, investigates rodent complaints under California Health and Safety Code §2270 and county ordinance. Inspectors document rat burrows, droppings, and harborage in yards, sheds, and trash areas. Owners receive written notice to remove food sources, seal openings, trim ivy, and trap or bait. Failure to comply triggers district abatement, with costs assessed as a lien on the property. Roof rats (Rattus rattus) are especially common in OC palm trees and citrus groves.
Refusal to abate within the notice period results in district contractor abatement plus a 25% administrative surcharge billed to the owner, plus possible misdemeanor citation.
