If a tenant in one of your Greater Waterbury apartments texts you about bed bugs tonight, Connecticut law gives you a short window to act — and the clock starts immediately. Understanding Connecticut landlord bed bug law responsibility under CGS § 47a-7a is not optional for multi-family owners. A missed deadline or a documentation gap can expose you to tenant lawsuits, habitability complaints, and an infestation that spreads to neighboring units before you’ve had a chance to respond.

Here is what the law requires, how to document it correctly, and why the stakes are especially high in a multi-family building during summer turnover season.

What Connecticut Law Actually Requires of Landlords (CGS § 47a-7a)

Connecticut enacted its bed bug statute — now codified as CGS § 47a-7a — in May 2016 through Public Act 16-51.
It lays out a step-by-step sequence of obligations that begins the moment a tenant notifies you of a suspected infestation.

Step 1: Tenant Notification Triggers the Clock

A tenant is required to promptly notify the landlord — orally or in writing — when the tenant knows or reasonably suspects that the dwelling unit is infested with bed bugs.
Once that notice is received, your obligations begin.

Step 2: Inspect Within Five Business Days — Including Contiguous Units

Not later than five business days after receiving notice, the landlord must inspect or obtain an inspection by a qualified inspector of the dwelling unit and any contiguous unit of which the landlord is an owner, lessor, or sublessor.
This is the provision that matters most in a multi-family building. A complaint in Unit 2B obligates you to look at the units next to it, above it, and below it — not just the unit where the complaint originated.

A “qualified inspector” under the statute is a certified applicator, a local health department official, or a bed bug detection team.

A bed bug detection team is defined as a scent detection canine team holding current, independent, third-party certification according to standards set by the National Pest Management Association.

If the landlord conducts the inspection personally rather than using a qualified inspector, the landlord must provide written notice to the tenant within two days indicating whether or not the unit is infested.
This two-day written notice requirement is easy to overlook and easy to miss without a system in place.

Step 3: Retain Pest Control Within Five Business Days of a Positive Inspection

If the qualified inspector determines that any unit is infested with bed bugs, the landlord must, not later than five business days after the date of such inspection, retain the services of a pest control agent.

Except as otherwise provided in the statute, the landlord is responsible for all costs associated with inspection for and treatment of a bed bug infestation.

There is one important distinction on costs:
a tenant is required to comply with reasonable measures to permit inspection and treatment, and that tenant is responsible for all costs associated with preparing the dwelling unit for such inspection and treatment.
Preparation costs (such as bagging linens or removing furniture from walls) are the tenant’s financial responsibility — treatment costs are yours.

The Prohibition on Re-Renting an Infested Unit

No landlord may offer for rent a dwelling unit that the landlord knows or reasonably suspects is infested with bed bugs.

Upon a prospective tenant’s request, the landlord must also disclose the last date on which the unit was inspected and found free of bed bugs.
During summer turnover season — when vacancies flip quickly — this disclosure obligation deserves extra attention.

What Happens If You Don’t Comply

If a landlord fails to comply with the statute, any tenant may pursue remedies under CGS § 47a-12 or § 47a-14h, and the landlord shall be liable to the tenant for reasonable attorney’s fees and the greater of $250 or the tenant’s actual damages.
That is a floor, not a ceiling — actual damages in a multi-unit infestation can climb well above $250 per unit.

There is also a tool available to landlords when tenants refuse to cooperate:
landlords who encounter obstinate tenants unwilling to comply with reasonable requests for entry, inspections, preparation, or treatments can apply to the Superior Court for injunctive relief. The process allows for an expedited hearing in which the tenant must show cause why an injunction should not issue, permitting the landlord to address the problem.

Why Multi-Family Buildings Amplify the Risk

Many landlords express frustration because when one tenant is uncooperative, the problem continues to spread throughout their buildings.
In a three-story walk-up, a single untreated unit is not a contained problem. Bed bugs travel through wall voids, pipe chases, and shared laundry facilities. By the time a second tenant reports a complaint, the infestation has had time to establish in multiple areas — and your five-business-day clock is now running on more than one front.

The regional context makes this timely.
Orkin’s 2025 rankings showed Hartford jumping 48 spots — the biggest single-year increase ever recorded — with contributing factors including older multi-family housing stock with shared wall voids, a heating rental market driving move-ins and secondhand furniture circulation, and the area’s position as a regional travel and lodging hub.
Greater Waterbury owners share the same housing stock profile: older multi-family buildings where a reactive approach is always more expensive than a fast one.

Summer compounds this. Tenant turnover is at its peak, and travel — which is a primary vector for bed bugs entering a building — is at its highest between June and August. If you are managing a vacancy right now, the leasing strategy you use during July and August should account for the possibility that an incoming tenant may unknowingly introduce an infestation. A documented pre-occupancy inspection is a reasonable safeguard.

Documentation: Where Most Landlords Fall Short

The strongest cases — for landlords and against landlords — are founded on paperwork. Landlords should be conscious of the obligation to provide notices as set forth in the statute and should document in writing the outcomes of investigations for bed bugs in the notices provided, in order to permit the tenants to contest findings as required.

All pest control records should be kept available should the landlord need to avail themselves of the injunctive relief provisions set forth in the statute.

At a minimum, your documentation file for any bed bug complaint should include:

• The date and method of the tenant’s initial notification (text, email, verbal — log it immediately)
• The date the inspection was ordered or conducted, and the name of the qualified inspector
• Written inspection findings, shared with the tenant within the statutory timeframe
• The date pest control was retained if infestation was confirmed
• Treatment reports and any follow-up inspection certifications
• Written records of any prep-cost repayment arrangements with the tenant

This file protects you if a tenant claims you failed to act, and it protects you at tenant turnover if the next prospective renter or a local health official asks when the unit was last cleared. At Premio Property Management, handling code and habitability issues with proper documentation — and moving quickly when a situation like this arises — is part of how we protect Greater Waterbury landlords in Waterbury, Watertown, Oxford, and Naugatuck.

If you manage other aspects of your properties carefully — your lease language around Connecticut’s 9-day grace period and late fee rules, for example — the same discipline applied to a bed bug complaint can keep you legally protected and your building’s habitability record clean.

Frequently Asked Questions

Can I charge a tenant for the cost of a bed bug inspection and treatment?

The statute is clear: the landlord is responsible for all costs associated with inspection for and treatment of a bed bug infestation.

However, the tenant is responsible for all costs associated with preparing the dwelling unit for inspection and treatment.
If a tenant fails to pay agreed preparation costs,
the landlord may deduct any remaining payments owed from the security deposit at the termination of the tenancy, in accordance with CGS § 47a-21.

What if my tenant refuses to let the pest control company into the unit?

Upon reasonable written or oral notice, a tenant must not unreasonably withhold access to the dwelling unit for the purpose of conducting a bed bug inspection or treatment.

If a court finds that a tenant has unreasonably failed to comply, it may issue a temporary order or interim relief, including granting the landlord access to the unit, granting the right to engage in inspection and treatment measures, or assessing the tenant with costs and damages related to noncompliance.
Document every access request in writing before pursuing court relief.

Do I have to disclose a past bed bug history to a new tenant?

If you know a unit is currently infested, you must disclose this to prospective tenants and cannot offer it for rent. Upon a prospective tenant’s request, you must also disclose the last date on which the unit was inspected and found free of bed bugs.
This is why maintaining written inspection records at every turnover — not just after a complaint — is good practice. Connecticut’s 2025 tenant protection law continues to raise the bar for habitability transparency, making thorough recordkeeping more important than ever.

The Bottom Line

Connecticut landlord bed bug law responsibility is specific, time-bound, and enforced. In a multi-family building, the cost of a slow response is measured in units, not just one apartment. Moving within five business days, inspecting contiguous units, documenting every step, and knowing your injunctive relief options are the four things that separate a managed situation from a costly one.
