Pests in a rental property: is the landlord or the tenant responsible?

Responsibility for pest control in a rented property depends on the cause. As a general rule the landlord is responsible where the infestation was present at the start of the tenancy, where it results from disrepair or a structural gap, or where it makes the property unfit to live in. The tenant is usually responsible where the problem is caused by how they live in the property, such as food waste or poor hygiene, or where they failed to report it promptly. The tenancy agreement can allocate everyday pest control to the tenant, but it cannot remove the landlord’s underlying legal duties.

Are landlords responsible for pest control?

In most serious cases, yes. A landlord’s repairing duty under Section 11 of the Landlord and Tenant Act 1985 covers the structure and exterior of the property, so where pests get in through a structural defect, a gap around pipework, a broken air brick or a damaged drain, dealing with both the entry point and the resulting infestation falls to the landlord. The infestations that become the landlord’s problem fastest are the ones with a structural cause, because that is disrepair rather than housekeeping.

A landlord is also responsible where an infestation was already present when the tenant moved in, and where it is serious enough to make the property unfit for human habitation. A significant rat or cockroach infestation can be a hazard under the Housing Health and Safety Rating System, which lets the local council inspect and, if needed, require the landlord to act. In a block of flats or an HMO, treatment of communal areas is the landlord’s or freeholder’s responsibility rather than any individual tenant’s. From 2026, the Decent Homes Standard and Awaab’s Law-style response timeframes extend to the private rented sector, which tightens how quickly a landlord must deal with serious hazards once they are reported. The general split between landlord and tenant repairs is summarised on gov.uk, and our repair obligations guide sets it out in full.

When is the tenant responsible for pest control?

A tenant is generally responsible where the infestation is a consequence of how they use the property. Leaving food waste exposed, failing to dispose of rubbish, or keeping the property in poor hygienic condition can all attract pests such as mice and rats, and where that is the cause the cost of treatment can reasonably fall to the tenant. A tenant who notices signs of pests and does not report them, allowing a minor issue to become an infestation, may also become responsible for the worsened problem. In a single let of a house, day-to-day nuisances such as the occasional ants or a wasp nest are often treated as the tenant’s to deal with, subject to what the agreement says.

The tenant’s duty to report is central. A property is required to be fit for human habitation, but the landlord can only act on a problem they know about, so prompt written notice protects the tenant and starts the landlord’s response clock.

What the tenancy agreement can and cannot do

Many tenancy agreements place responsibility for routine pest control on the tenant, and that is enforceable for issues the tenant causes. What an agreement cannot do is contract out of the landlord’s statutory duties. A clause that tried to make the tenant responsible for repairs to the structure, or for an infestation that makes the home unfit, would be void to that extent, because the duties under Section 11 and the fitness-for-habitation rules cannot be excluded by agreement. In practice this means the agreement decides the everyday, low-level cases, while the law decides the serious and the structural ones.

Common pests and who usually deals with them

Mice and rats almost always enter through gaps and structural defects, so they tend to be the landlord’s responsibility, both to seal the entry points and to treat the infestation; this is the most searched single case and the answer is usually the landlord. Cockroaches in a block are frequently building-wide and point to the landlord or freeholder rather than one flat. Bedbugs are more contested, because they are often introduced on belongings or furniture, which can place them with the tenant, although a pre-existing infestation remains the landlord’s. Seasonal nuisances such as wasp nests and ants are commonly handled by the tenant in a single let unless the agreement says otherwise.

What to do about an infestation

For a tenant, the first step is to report the problem to the landlord or agent in writing, with photographs and dates, and to keep the property clean while it is dealt with. For a landlord, the right response is to investigate quickly, identify whether the cause is structural or behavioural, arrange professional treatment where the responsibility is theirs, and fix any entry point so the problem does not return. Across the landlords using August, pest disputes turn on two facts, whether the infestation was present at the start and how quickly it was reported, so a dated record of both is what decides who pays. Logging the report and the response, and tracking the work through to completion, is exactly what maintenance tracking is for, and it doubles as evidence if the council or a repair report becomes involved.

Frequently asked questions

Are landlords responsible for pest control in the UK?

Usually, where the infestation was present at the start of the tenancy, results from disrepair or a structural gap, affects communal areas, or makes the property unfit to live in. In those cases the landlord must deal with both the cause and the infestation.

Is a tenant responsible for pest control?

A tenant is generally responsible where the problem is caused by how they live in the property, such as food waste or poor hygiene, or where they failed to report it and allowed it to worsen. Everyday nuisances in a single let are often the tenant’s too, subject to the agreement.

Are landlords responsible for mice and rats?

In most cases, yes, because mice get in through structural gaps that fall under the landlord’s repairing duty. The landlord should seal the entry points as well as treat the infestation.

Can a landlord make the tenant pay for pest control?

Only where the tenant caused the infestation or the tenancy agreement reasonably allocates routine pest control to them. A landlord cannot pass on responsibility for a structural cause or for an infestation that makes the home unfit.
