Pest Control: A Guide to Common Household Pests

Quick Answer: How Do You Deal With Common Household Pests?

Common UK household pests including mice, rats, wasps, ants, and moths each require different treatment approaches, though prevention through sealing entry points, removing food sources, and maintaining general cleanliness addresses the root cause of most infestations. Professional pest control typically costs £80 to £300 depending on the pest and severity, while many minor issues can be managed with DIY treatments.

Common UK Household Pests

Mice and Rats

Rodents are among the most common UK household pests, entering through surprisingly small gaps and often detected via droppings, gnaw marks, or scratching sounds, particularly at night. They can cause structural damage by gnawing wiring and pose genuine hygiene and health risks.

Wasps

Wasp nests commonly appear in lofts, eaves, and garden sheds during summer months, growing rapidly once established. Nests are best treated by professionals given the sting risk involved in DIY removal, particularly for larger, established nests.

Ants

Ants are typically a nuisance rather than a structural threat, entering homes in search of food, particularly in summer. Trails often lead back to a nest that, once located, can usually be treated directly for effective control.

Moths

Clothes moths damage natural fibres like wool and silk, while pantry moths infest dry food stores. Both require identifying and removing the source, whether an infested garment or contaminated food packet, alongside targeted treatment.

Bed Bugs

Increasingly common in UK homes, bed bugs are notoriously difficult to eliminate without professional treatment, given their ability to hide in tiny gaps and resist many DIY treatment attempts.

Signs of a Pest Infestation

Preventing Pest Infestations

• Seal gaps around pipework, air bricks, and any external wall openings that could allow rodent entry
• Store food, particularly dry goods, in sealed containers rather than original packaging
• Keep bins covered and cleared regularly, since exposed waste attracts numerous pest types
• Address any damp or clutter that provides hiding spots for pests
• Check and clean gutters, since stagnant water and debris can attract insects

DIY vs Professional Pest Control

When to Call a Professional Pest Controller

DIY treatments work well for minor, early-stage issues, but persistent, recurring, or large-scale infestations, particularly rats, established wasp nests, or bed bugs, generally warrant professional intervention given the specialist knowledge, equipment, and stronger treatments involved.

Who Is Responsible for Pest Control: Landlord or Tenant?

In rented homes, who pays for pest control depends on what caused the infestation. The general rule is straightforward: the landlord is responsible where the problem comes from the property itself, and the tenant is responsible where it comes from how they live in it. The table below covers the most common situations.

The legal backbone is the landlord’s repairing duty under Section 11 of the Landlord and Tenant Act 1985, which covers the structure and exterior of the property. Where pests get in through a structural defect, fixing the defect and treating the infestation both fall to the landlord. A serious rat or cockroach infestation can also be a hazard under the Housing Health and Safety Rating System, allowing the local council to inspect and require the landlord to act. Note that a tenancy agreement can allocate everyday pest control to the tenant, but it cannot remove the landlord’s underlying legal duties. If you are a tenant, report any pest problem to your landlord in writing as soon as you notice it, with photos, since late reporting can weaken your position.

Frequently Asked Questions

How do mice get into a house?

Mice can squeeze through remarkably small gaps, often around pipework, air bricks, or minor gaps in external walls, which is why sealing potential entry points is a key prevention step.

Are wasp nests dangerous to remove yourself?

Removing a wasp nest without proper protective equipment and experience carries genuine sting risk, particularly for larger, established nests, so professional removal is generally recommended.

How do you know if you have bed bugs?

Small, itchy bites in a line or cluster, tiny blood spots on bedding, and visible bugs or shed skins in mattress seams are common signs, and professional confirmation is recommended given how easily bed bugs can be misidentified.

Can pest control treatments harm pets?

Some treatments can pose risks to pets, so informing a professional pest controller about any pets in the home ensures they use appropriate, pet-safe products and methods where possible.

How long does it take to get rid of mice?

This depends on infestation size, but with effective trapping and entry point sealing, a minor mouse issue can often be resolved within a few weeks, while larger infestations may take longer.

Is my landlord responsible for pest control?

In most cases, yes, where the infestation comes from the property’s condition: pre-existing problems, structural gaps, faulty drains or disrepair. The landlord is also responsible where the infestation is serious enough to make the home unfit to live in. The tenant is usually responsible only where their own hygiene or behaviour caused the problem.

Can a landlord charge a tenant for pest control?

A landlord can seek the cost from the tenant where the infestation was clearly caused by the tenant, such as poor hygiene or waste left to accumulate, and may deduct it from the deposit. They cannot fairly charge the tenant for problems caused by disrepair or pre-existing infestations.

What should I do if my landlord ignores a pest problem?

Put the complaint in writing with dates and photos, and keep copies. If the landlord still does not act, contact your local council’s environmental health team, who can inspect the property and require the landlord to deal with serious pest hazards.

Are tenants responsible for wasp nests?

It depends on the cause. A wasp nest in the eaves of the building fabric is normally the landlord’s responsibility as part of the structure. A nest the tenant could reasonably have prevented, or one in a shed they use exclusively, may fall to the tenant. Check the tenancy agreement first.

Does the tenancy agreement decide who pays for pest control?

The agreement matters and should be checked first, since it may allocate everyday pest control to the tenant. However, it cannot override the landlord’s statutory duties: a clause cannot make the tenant responsible for disrepair or for a home that is unfit to live in.

Expert Insight

Pest control professionals consistently emphasise that prevention, sealing entry points and removing food sources, is more effective long-term than repeatedly treating recurring infestations without addressing why pests are getting in and finding food in the first place.

Final Thoughts

Dealing with household pests effectively starts with correct identification, followed by a proportionate response, DIY for minor issues, professional help for larger or more resistant infestations. Consistent prevention through sealing entry points and good food storage habits reduces the likelihood of recurring problems significantly.

Dealing with a pest problem? Address the entry point or food source alongside any direct treatment, since removing pests without fixing how they got in or what attracted them often leads to the same problem recurring.
