Connecticut Bed Bug Law for Landlords: What You Are Required to Do

A bed bug complaint in a rental comes with legal duties in Connecticut. Since October 2016, state law (Public Act 16-51) has set clear responsibilities for landlords and tenants in residential rentals, including apartment buildings, multi-family homes, and public housing. Detached single-family homes are excluded. Here is a plain-language overview for property owners in Waterbury, Southington, and surrounding towns.


Your Timeline After a Tenant Reports Bed Bugs

Within five business days of a tenant's report, you must inspect, or have a qualified inspector inspect, the unit and any contiguous units you own, lease, or sublease. If you do the inspection yourself, the tenant must receive written results within two days.


If bed bugs are found, reasonable treatment of the unit and contiguous units must begin within five business days of the inspection. The landlord pays for both inspection and treatment.


What the Law Requires Beyond Treatment

  • Do not rent a unit you know or reasonably suspect has bed bugs.
  • Tell prospective tenants whether the unit or a contiguous unit is currently infested.
  • On request, share the last date the unit was inspected and found free of bed bugs.
  • Give reasonable notice before entering for inspection or treatment.


What Tenants Are Responsible For

Tenants must report suspected bed bugs promptly, allow access after reasonable notice, cover the cost of preparing their unit, and follow treatment instructions. A tenant who unreasonably fails to comply can be held responsible for added treatment costs.


How ProSource Supports Connecticut Landlords

We inspect the reported unit and neighboring units, document our findings in writing, and complete a two-treatment program with a follow-up visit about two weeks after the first. Inspections are $100 and are credited toward treatment if you move forward. Learn more about our bed bug treatment, pest control for multi-unit rentals, and why landlord approval matters.



Frequently Asked Questions

  • How long does a Connecticut landlord have to respond to bed bugs?

    A Connecticut landlord has five business days after a tenant’s report to inspect, or have a qualified inspector inspect, the unit and any contiguous units the landlord owns, leases, or subleases. If bed bugs are found, the landlord must take reasonable steps to treat the unit and contiguous units within five business days after that inspection.

  • Who pays for bed bug treatment in a Connecticut rental?

    The landlord pays for bed bug inspection and treatment. Tenants cover the cost of preparing their unit, such as laundering clothing or moving furniture. If a tenant knowingly and unreasonably fails to follow inspection or treatment steps, that tenant can be held responsible for additional treatment costs for their unit and neighboring units.

  • Does Connecticut’s bed bug law apply to single-family homes?

    No. The law covers residential rental properties such as apartments, multi-family homes, and public housing, but it excludes detached single-family homes. Owners renting a detached house still have a general duty to keep the home fit and habitable, so a professional inspection is still a smart step if a tenant reports bed bugs.

  • Can a landlord treat bed bugs themselves in Connecticut?

    Yes, with conditions. A landlord who treats on their own must vacuum the areas first, have a qualified inspector check the unit within five business days after treatment, and get written certification that the unit is no longer infested. If the treatment did not work, the landlord must hire a pest control professional within five business days.

  • Do I have to inspect neighboring units for bed bugs?

    Yes. Connecticut law requires landlords to inspect the reported unit and any contiguous units they own, lease, or sublease. Bed bugs can travel between units, so checking neighboring units early helps keep a single-unit problem from spreading through the building and lowers the cost of treatment overall.
