Dealing with Pesky Pests
As temperatures soar during the summer months, so too does pest activity. Heatwaves create ideal conditions for insects and rodents, resulting in a noticeable increase in reports of ants, flies, wasps, rodents and other unwelcome visitors finding their way into rental homes.
Whilst many pest issues are relatively straightforward to resolve, they can quickly become probelmatic if it is unclear who is responsible for dealing with them. This is where a well-drafted tenancy agreement, supported by good communication between landlord and tenant, becomes invaluable.
Why are pests more common during a heatwave?
Warm weather accelerates breeding cycles and encourages pests to search for food and water. Open windows and doors provide easy access for flying insects, whilst dry ground often drives rodents indoors in search of something to drink.
Common summer pests include:-
Ants invading kitchens in search of food.
Flies attracted to food waste and rubbish.
Wasps nesting in roof spaces, lofts and gardens.
Moths damaging clothing and soft furnishings.
Rodents entering through small gaps in search of food and water.
Although these issues are more prevalent during periods of hot weather, they are not always the result of poor housekeeping. Environmental conditions can significantly increase pest activity, even in well-maintained homes.
What should the tenancy agreement say?
A in-depth tenancy agreement should clearly define each party's responsibilities throughout the tenancy. Whilst the exact wording may vary, agreements commonly include obligations requiring tenants to:-
Keep the property reasonably clean and hygienic.
Dispose of household waste appropriately.
Store food safely.
Take reasonable steps to prevent infestations.
Report signs of pests promptly.
Allow access where treatment or repairs are required.
Many agreements also require tenants not to do anything that may attract vermin or insects through neglect or poor housekeeping.
Equally, landlords have contractual and legal responsibilities. They should ensure the property is provided in a good state of repair at the start of the tenancy and maintain the structure and exterior throughout the tenancy. Defects such as broken air bricks, damaged drains, holes in external walls or defective pipework can all contribute to pest ingress and should be addressed without unnecessary delay.
Contract versus Responsibility
One of the most common misconceptions is that tenants are automatically responsible for every pest issue. In reality, responsibility depends upon the cause.
If an infestation results from the tenant's actions—for example, leaving food waste out in the open, failing to remove rubbish or maintaining poor standards of cleanliness—the tenancy agreement may enable the landlord to require the tenant to remedy the issue and, where appropriate, recover reasonable costs.
However, where pests gain entry because of structural defects, disrepair or conditions that existed before the tenancy commenced, responsibility is likely to rest with the landlord. Simply relying on a clause within the tenancy agreement will not usually transfer responsibility for repairing the building or complying with statutory repairing obligations.
The circumstances of each case should therefore be assessed individually.
Property Inspections
Summer is an excellent opportunity for routine property inspections. During inspections, landlords and letting agents should look for:
Evidence of rodent activity.
Ant trails around kitchens.
Overflowing refuse storage.
Gaps around pipework and external doors.
Damaged air vents or air bricks.
Overgrown vegetation providing harbourage for pests.
Early identification often prevents a relatively minor issue from becoming an expensive infestation.
Prevention benefits everyone
Simple preventative measures can significantly reduce the likelihood of pest problems:
Empty internal bins regularly.
Keep external refuse areas tidy.
Store food in sealed containers.
Repair gaps around doors and pipework.
Fit fly screens where appropriate.
Remove standing water.
Keep gardens maintained.
These small steps can save considerable time, inconvenience and expense.
Communication is key
Perhaps the most important clause in any tenancy agreement is the obligation to report problems promptly.
A tenant who notices the first signs of rodents or insects should notify the landlord or managing agent immediately rather than attempting to ignore the issue. Likewise, landlords should respond promptly by investigating the cause and arranging appropriate treatment where necessary.
Early intervention almost always results in a quicker, less costly resolution.
A timely reminder
Heatwaves are becoming increasingly common in the UK, and with them comes an increase in pest-related issues. Landlords should take this opportunity to review their tenancy agreements to ensure responsibilities are clearly defined, whilst also remembering that contractual terms operate alongside statutory obligations and cannot exclude legal repairing duties.
Clear agreements, regular inspections, prompt reporting and proactive maintenance remain the best defence against seasonal pest problems—helping to protect both the property and the landlord–tenant relationship.
