Twain Harte, CA Public Health Rules: Bed-Bug Rules (2026)

1954.600. The Legislature finds and declares: (a) Controlling bed bugs is uniquely challenging, as bed bug resistance to existing insecticidal control measures is significant. Cooperation among landlords, tenants, and pest control operators is required for successful control. With cooperation among landlords, tenants, and pest control operators, most bed bug infestations can be successfully controlled. (b) Effective control is more likely to occur when landlords and tenants are informed of the best practices for bed bug control. (c) Early detection and reporting of bed bugs is an important component required for preventing bed bug infestations. Tenants should not face retaliation for reporting a problem. (d) Lack of cooperation by landlords and tenants can undermine pest control operator efforts to identify the presence of bed bugs and control an infestation. Depending on the treatment strategy, it is often critical that tenants cooperate with pest control operators by reducing clutter, washing clothes, or performing other activities. Likewise, inadequate or untimely response or planning by landlords may exacerbate an infestation. (e) Pest control operators with knowledge and education in current best practices for bed bug management, such as those created by the National Pest Management Association (NPMA), are best equipped to help property owners and tenants eradicate bed bugs from their home.
