In Massachusetts, there are specific laws and guidelines regarding pest control responsibilities in rental properties.
Whether you are dealing with a single mouse or a serious infestation, understanding the Massachusetts State Sanitary Code is essential for ensuring a healthy and habitable living environment.

2. The Massachusetts State Sanitary Code
The State Sanitary Code (105 CMR 410.000) regulates the maintenance and habitability of rental properties. It outlines exactly who is responsible for what.
Landlord Responsibilities
Under Massachusetts law, landlords must provide tenants with a habitable dwelling free from conditions that may endanger health or safety.
3. Tenant Responsibilities
While landlords are responsible for addressing infestations, tenants still play a critical role in preventing and managing pest issues.
Maintain a Clean Environment
Tenants are expected to keep their unit in a clean and sanitary condition. This includes storing food properly, taking out trash regularly, and minimizing clutter that can attract or hide pests. At the first sign of pest activity, tenants should notify the landlord promptly to prevent the issue from worsening.
Cooperate with Treatment and Inspections
When an infestation is reported, tenants must cooperate with the landlord and any licensed pest control professionals. This may involve preparing the unit for treatment, such as clearing cabinets, moving furniture, or temporarily vacating the apartment if required. Refusing to cooperate can delay treatment and may make the tenant responsible for resulting damages.
4. How to Force Action: The 311 Strategy
If your landlord is ignoring the State Sanitary Code, it’s time to involve the city.
- Notify in Writing: Send an email explaining the issue and requesting professional treatment.
- Call 311: If they don't respond, call 311 or use the BOS:311 app.
- Request an ISD Inspection: Ask for an inspection from the Inspectional Services Department (ISD).
- The Violation Notice: An official state violation notice is the most effective way to force a landlord to pay for professional repairs.
5. Prevention Checklist
A proactive approach is the most effective way to keep your unit pest-free.
1. Seal All Physical Entry Points
Boston's older buildings are full of hidden highways for pests.
- Pipes & Radiators: Pack gaps around radiator pipes and sink drains with steel wool and caulk. These often connect units through floorboards.
- Doors & Windows: Install door sweeps if light passes under your door and ensure window screens are tight in their frames.
- New Cracks: Buildings shift; check baseboards and floor corners regularly for new openings.
2. Manage Food & Waste Strategically
Pests are drawn more to timing and accessibility than total volume.
- Airtight Storage: Move pantry items from original cardboard/plastic into sealed glass or plastic containers.
- Trash Timing: Take out trash every night, even a small amount. Shared trash rooms are often the source of infestations—report poorly maintained common trash areas to your landlord.
- Invisible Crumbs: Clean under appliances and wipe grease from stovetops; even small residues can support cockroaches.
3. Eliminate Moisture & Shelter
Remove the two things pests need most: water and a place to hide.
- Fix Leaks: Report condensation on pipes or slow leaks under sinks immediately. Water is often the limiting factor for an infestation.
- Ditch Cardboard: Cardboard boxes and paper bags provide ideal warmth and moisture for nesting. Use plastic bins for storage instead.
4. Report Single Sightings Immediately
One sighting is rarely just one. Early reporting prevents pests from spreading into walls and shared building systems. Never wait for it to "get worse" before notifying your landlord in writing.
