California Structural Pest Control Act (B&P Code §8500+) requires licensed operators for pest treatments. LA County Environmental Health enforces vector control in unincorporated areas. Termite reports are required for most real estate transactions.
Structural pest control in LA County is regulated by the California Structural Pest Control Board under Business and Professions Code §8500–8698. All operators must be licensed. Fumigation requires notification of neighbors within 15 feet, posting warning signs, and using secondary locks. The LA County Department of Public Health Vector Management Program handles mosquitoes, rodents, and other disease vectors in unincorporated areas. For real estate transactions, a Wood-Destroying Organism (WDO) inspection report (formerly 'termite report') is commonly required by lenders. Property owners in unincorporated areas can request vector control services at no charge from the Greater Los Angeles County Vector Control District. Landlords must maintain rental units free of pest infestations as part of habitability requirements under Civil Code §1941.1.
Unlicensed pest control work: misdemeanor with fines up to $10,000 (B&P §8553). Fumigation violations carry additional penalties. Landlords failing to address infestations may face habitability complaints and rent withholding.
