MO HB1849

Landlords must use reasonable efforts to maintain multifamily rental units free of bed bug infestations and must inspect units within 7 days of written tenant notice of suspected bed bugs.

Landlords must begin bed bug control within 14 days of confirming an infestation and must notify tenants in surrounding units; only the landlord or designated pest control professional may apply control treatments.

Tenants must report suspected bed bugs to the landlord in writing within 48 hours and must grant landlords 24-hour notice access for inspections and treatments; failure to report within 7 days of move-in constitutes acceptance that the unit is bed bug-free.

Landlords are not liable for damages from bed bugs or their control except in cases of gross negligence, and tenants who fail to report infestations or obstruct treatment may be liable for treatment costs and lease violations.

Bed bug control is deemed complete when there is no evidence of bed bug activity for 50 days after the last treatment application.
