Who Is Responsible for Pest Control in a Rental Property?

Pests can often create friction between landlords and tenants. When ants appear on worktops or rodents move through the walls, the question is, who is responsible for dealing with them? Across California and other states, pest control in rental properties follows a split based on law and practical responsibility. 

Landlords are responsible when pests are linked to the building’s structure or pre-existing conditions. Tenants are responsible when infestations arise from their day-to-day living habits. However, lease terms, local rules, and specific facts can shift where the duty ultimately falls. 

This guide explains why the answer matters: it decides who pays, how quickly treatment happens, and whether the property stays habitable.

Are Landlords Responsible for Pest Control?

In most cases, yes. Landlords are responsible for pest control, especially when the problem is linked to the property itself rather than how the tenant lives.

This responsibility comes from the legal requirement to provide a habitable home. In plain terms, that means a rental must be safe and fit to live in. A serious pest problem, especially one that affects health or damages the building, usually breaks that standard.

Landlords are typically responsible when:

• Pests come from structural issues (gaps, cracks, faulty foundations, damaged roofs, etc.)
• Infestations exist before a new tenant moves in
• Pests spread through shared or common areas, like hallways, basements, or attics
• The problem affects multiple units in the same building

Examples:

• Termites are eating away at support beams
• Rats are entering through holes in the exterior walls
• Bed bugs found shortly after move-in, coming from previous occupants

In these situations, tenants did not cause the problem, and they cannot reasonably fix the underlying issue themselves. The landlord controls the structure, so the landlord must deal with it.

Understanding Default Landlord Responsibilities

In most jurisdictions, including California, landlords are legally required to keep rental properties free from serious pest infestations. They must also repair defects that allow pests to enter, such as gaps, broken vents, or damaged pipes.

Landlords are expected to deal with pest problems that affect multiple tenants or shared areas and to arrange professional pest control when issues are significant or recurring.

Even when a tenant’s behavior contributes to the problem, landlords usually still need to act once an infestation affects habitability or spreads beyond a single unit. They may then try to recover some or all of the costs from the tenant if there is clear evidence that the tenant caused the issue. However, their core duty to provide a safe, livable home remains.

Who Is Responsible for Extermination: Tenant or Landlord?

When deciding who is responsible, the key question is

What caused the infestation?

Generally:

Landlords pay when pests are linked to:

• Structural defects
• Poor maintenance
• Long-term moisture or plumbing issues
• Problems that existed before the tenancy began
• Pests originating in shared spaces or neighbouring units

Tenants may pay (at least in part) when:

• Unsanitary living conditions attract pests
• Rubbish is not stored or disposed of properly
• Food is left out regularly
• Tenants damage or remove screens, weatherstripping, or seals that keep pests out

California law requires landlords to maintain a pest-free, habitable property, and many other states follow similar principles. However, the exact rules can differ by state and even by city. A lease cannot remove basic habitability rights, even if it tries to push all pest control costs onto tenants.

If there is doubt, tenants and landlords should check:

• Local housing codes
• State landlord–tenant laws
• City or county regulations
• Any guidance from local housing or health departments

Who Handles Pest Control When Renting?

In practice, who is responsible for pest control when renting usually comes down to what caused the problem. If pests are getting in because of building defects, such as holes in exterior walls or moisture from leaking pipes that attract termites, the landlord is normally responsible. These issues relate to property maintenance, not how the tenant lives.

Responsibility can shift towards the tenant when their habits clearly create the conditions for an infestation. Leaving food uncovered, letting rubbish build up, or allowing the home to become unhygienic can attract pests like roaches, and the tenant may be asked to cover some or all of the cost. Even then, landlords often still need to arrange professional pest control, especially in flats or multi-unit buildings, to stop the problem from spreading and to keep the property habitable.

Common Pests and Responsibility Divisions in Rental Properties

While the exact answer can vary, here is a helpful rule of thumb:

Bedbugs

Often treated as a landlord’s responsibility because they affect habitability and spread easily between units. Many areas expect landlords to handle bed bug infestations promptly, regardless of blame.

Roaches

• A few roaches due to poor housekeeping: the tenant may share responsibility.
• Widespread roach problems across units or in common areas: usually the landlord.

Termites

Almost always the landlord’s responsibility. They are structural pests and require professional treatment and often repairs.

Rodents (rats and mice)

• Entering through building defects: landlord.
• Attracted by poor food storage or rubbish inside a single unit, the tenant may share responsibility, but the landlord typically coordinates control to protect the building.

Ants, spiders, and occasional invaders

• Small, one-off problems can be part of general household upkeep (tenant).
• Persistent or building-wide issues may signal structural or moisture problems (landlord).

In all cases, ignoring pest problems usually makes them worse and more expensive. Whoever is responsible should act quickly.

What Tenants Should Do If Landlords Ignore Pest Problems

If you’re a tenant and your landlord isn’t taking pest issues seriously, follow a clear, simple process:

Document everything

Keep a clear record of the problem by taking photos or videos of pests and any damage you can see. Note the dates, times, and where in the property you found them, as this helps show how serious and ongoing the issue is.

Notify the landlord in writing

Contact your landlord by email, text, or letter so there is a written record of your report. Explain what pests you are seeing and where they appear, and ask for professional pest control within a reasonable timeframe.

Keep copies of all communication

Save every message you send and receive about the issue, including emails, texts, and letters. These records can be important if you need to prove what was reported and how your landlord responded.

Contact local authorities if needed

If your landlord does not act and the infestation affects your health or safety, you can contact your local housing or environmental health department. They may be able to inspect the property and require the landlord to carry out repairs or treatment.

Know your legal options

In some places, tenants may be allowed to arrange pest treatment and recover the cost, but strict rules usually apply. Always check local law or speak to a tenant advice service or legal professional before withholding rent or taking formal action.

Best Practice for Landlords: Staying Ahead of Pest Issues

Landlords who manage pest control proactively protect both their investment and their relationship with tenants. Good practice includes:

Inspect at move-in and move-out

Inspect the property thoroughly at the start and end of each tenancy, noting any signs of pests or entry points. Fix problems before new tenants move in to prevent infestations from taking hold.

Carry out regular inspections

Plan periodic inspections during the tenancy to spot early signs of pests or maintenance issues. Dealing with small problems quickly is far cheaper and easier than handling a full infestation.

Include clear pest control clauses in the lease

Set out in the tenancy agreement what you will take responsibility for, such as structural issues and professional treatments when needed. Clearly explain what you expect from tenants, including basic cleanliness, rubbish storage, and prompt reporting of pest activity.

Schedule routine professional pest control

Consider arranging regular visits from a pest control professional, especially for multi-unit or high-risk properties. Routine treatments can prevent many infestations and show tenants that you take their living conditions seriously.

Respond quickly to reports

Act promptly when tenants report pests or conditions that might attract them. Fast, professional responses reduce damage, lower long-term costs, and help maintain a positive landlord–tenant relationship.
