If you suspect you have a bug infestation in your rental home, quickly understanding who is responsible is important for solving the problem and fixing any house disrepair. 

Sometimes, responsibility will be easy to identify – for example, if bins are overflowing, food is left out, or there’s a lack of general hygiene in the property, the fault would lie with the tenant. 

However, if the infestation is a result of poor habitable conditions or structural issues, the fault may rest with the landlord. 

This guide will break down who should be responsible in which scenario, what type of bug infestations are considered as ‘pests’ in UK law, and what to do if you have a bug infestation in your home.

What are the laws on the responsibility of bug infestations?

Under UK law, landlords are required to ensure safe and habitable living conditions, which include addressing pest infestations, such as bugs. This duty is outlined in the Landlord and Tenant Act (1985).

Local councils and courts often use the Housing Health and Safety Rating System (HHSRS) to interpret and enforce these obligations in dispute cases.

However, the Act doesn’t cover every possible pest infestation scenario, so responsibility can sometimes be disputed. Bug infestations could include, but aren’t limited to:

  • Cockroaches: Resilient and known for contaminating food and spreading diseases, cockroaches can be found in warm, damp environments, like kitchens or bathrooms.
  • Ants: Ant infestations are commonly found near food spills or crumbs, as ants tend to scavenge for food.
  • Silverfish: Nocturnal by nature, silverfish feed on carbohydrates, such as paper and glue, preferring bathrooms or basements with moist, humid environments. 
  • Wasps: Wasp nests can be found in loft spaces, basements or under floorboards. It’s important to use a trusted professional to get rid of wasp nests.
  • Fleas: A common byproduct of having pets, fleas are small and red-brown in colour, known for their jumping ability.
  • Flies: Fruit flies or house flies may appear when rubbish hasn’t been properly disposed of, or food is left out on the side.
  • Bed bugs: While commonly found in bedrooms on mattresses, bed bugs can also hide in other furniture, like sofas, or in cracks and crevices.

Below, we explain when the landlord is legally liable for bug infestations and when the tenant may be at fault.

When is a bug infestation the landlord’s responsibility?

Landlords are generally responsible for any type of bug infestation when the problem stems from their failure to meet their legal duties.

They may be liable if:

  • The infestation was present before the tenant moved in: This suggests that the property was uninhabitable at the start of the tenancy.
  • Structural issues: If issues such as cracks, leaks, or damp are attracting the bugs.
  • Multiple units are affected: This can be common in blocks of flats, for example.
  • It’s stated in the agreement: If the tenancy agreement states that pest control (including dealing with bug infestations) is the landlord’s responsibility.

What about for House in Multiple Occupation (HMO) landlords?

HMO landlords have extra responsibilities when it comes to bug infestations in shared properties. If any bugs are found in communal areas, then it is instantly the landlord’s duty to deal with the problem.

However, if the infestation results from the tenants’ behaviour (such as uncleanliness, leaving food out, or not emptying bins), they will be responsible, just as they would be in a standard tenancy.

When is a bug infestation the tenant’s responsibility?

As a tenant, you could be responsible for a bug infestation if your behaviour is the reason why the bugs have infiltrated your home in the first place. 

The tenant could be legally responsible for bug infestations due to:

  • General uncleanliness: This could be not emptying the bins, leaving food sitting out, not vacuuming up crumbs and pieces of food, or general poor hygiene and sanitation.
  • Negligence: If you haven’t immediately reported the incident, you can be liable for any house disrepair that has happened as a result of the bug infestation. 
  • If stated in the agreement: If the tenancy agreement states that it’s the tenant’s responsibility to deal with bug infestations, then you are legally liable to do so.

What to do if you have a bug infestation in your home? Step-by-step guide

1. Check the tenancy agreement

First things first, if you suspect you have a bug infestation – whether it’s ants, wasps, termites or cockroaches – you should check your tenancy agreement to see if there are any clauses relating to pest infestations in the home. 

The agreement might state whether the tenant or landlord is responsible, or it might not mention it at all. Either way, reviewing it first can save time and help resolve the issue faster.

2. Document the issue

Spotted a wasp’s nest in your loft? Signs of termites in your woodwork? Cockroach droppings and odours? Whatever the infestation, make sure you take multiple photographs as evidence. You should also take photos and document any areas of house disrepair that the bugs have caused. 

It’s also helpful to keep a note of any dates and details relating to the infestation. That way, you can prove how long you’ve been monitoring it, and if there’s any resistance from the landlord, this could be used as evidence of neglect.

3. Alert your landlord to the problem

The next step is speaking to your landlord and alerting them to the issue, regardless of who’s at fault or who’s responsible for it.  

Make sure you keep all communications with your landlord carefully documented, as, if they don’t cooperate, you’ll then have proof that they were informed and the issue was not dealt with promptly. 

They may offer to help with the bug infestation, or they may advise you to sort things out on your own. They could also want to come and see the infestation for themselves, especially if it’s caused any house disrepair.

4. Getting rid of the bug infestation

The way you get rid of bugs depends on the type of infestation. For example, cockroaches will need to be treated with bait traps, insecticidal sprays and by eliminating food sources, whereas bed bugs will need thorough heat treatment, deep cleaning of bedding and furniture, and often professional pest control to fully eradicate them.

Whether your landlord is helping you to get rid of the ant infestation or not, acting quickly with a bug infestation is important to reduce the likelihood of it spreading or causing house disrepair. 

If the infestation is serious or ongoing, it’s best to contact professional pest control services, which is something the landlord is typically responsible for organising and covering.
