Published 2 January 2026

As the colder months approach, pest infestations become a growing concern for households across West London.

At On Time Pest Control, we specialise in offering tailored solutions to safeguard homes against seasonal pest problems.

Winter brings with it a drop in temperature and limited food resources outdoors.

Unlike in summer, when pests often stay outside, winter pests thrive inside homes and can cause significant issues including:

Unlike in summer, when pests often stay outside, winter pests thrive inside homes and can cause significant issues including:

• Structural damage caused by gnawing Rodents.
• Health risks through the spread of bacteria, viruses, and allergens.
• Food contamination from stored product pests and insects.
• High repair costs if infestations are left untreated.

Rodents can squeeze through gaps as small as a pencil, and insects find their way through the tiniest cracks.

Check external walls:
Look for cracks in brickwork, damaged mortar, and openings around pipes. Seal gaps with caulk or wire mesh.

Secure doors and windows:
Ensure frames are tight-fitting. Install weather stripping and door sweeps to eliminate gaps.

Inspect vents and chimneys:
Use fine wire mesh or specialist covers to prevent entry without blocking airflow.

Basement and loft access:
Pay special attention to roof tiles, soffits, and eaves where pests often sneak inside.

rats and mice are among the most common winter pests in London.

Keep food sealed:
Store dry goods in airtight containers, not cardboard boxes.

Eliminate nesting sites:
Clear clutter from lofts, garages, and sheds where Rodents may settle.

Inspect gardens:
Overgrown shrubs, piles of wood, and compost heaps attract Rodents and provide shelter.

Professional rodent-proofing:
At On Time Pest Control, we use tamper-proof bait stations and advanced monitoring systems to secure your home against Rodents throughout the winter.

Though many insects hibernate in winter, some species thrive indoors during the colder months.

Check damp areas:
Bathrooms, basements, and kitchens are prime spots for insect activity due to excess moisture.

Eliminate standing water:
Leaky pipes, dripping taps, and poor ventilation create breeding grounds.

Pantry inspection:
Dispose of infested food items immediately and clean cupboards thoroughly.

Use natural deterrents:
Bay leaves, cedarwood, and peppermint oil can repel certain insects when placed in cupboards and storage spaces.

Poor waste management is one of the leading causes of winter pest infestations.

Secure outdoor bins:
Ensure wheelie bins have tight lids and are cleaned regularly.

Avoid overnight exposure:
Do not leave bin bags outdoors overnight where Rodents and foxes can access them.

Compost carefully:
Use sealed compost bins rather than open heaps, as they attract vermin.

Indoor waste control:
Empty kitchen bins frequently and clean them with disinfectant.

Cleanliness plays a vital role in preventing pests.

Vacuum frequently:
Pay special attention to skirting boards, behind furniture, and under appliances.

Declutter storage areas:
Lofts, garages, and under-stair cupboards often harbour pests if left unchecked.

Launder fabrics:
Wash bedding, curtains, and upholstery regularly to prevent moths and dust mites.

Reduce humidity:
Use dehumidifiers or improve ventilation to make your home less appealing to pests.

Pests often begin outside before finding their way indoors. Winter-proofing your garden is a critical step.

Trim vegetation:
Keep bushes, shrubs, and trees away from walls and windows to reduce rodent access routes.

Store firewood properly:
Keep logs at least 20 feet from the house and elevated off the ground.

Secure sheds and garages:
Ensure doors close properly and seal any gaps in the walls or floor.

Inspect drainage:
Blocked drains can attract Rodents and insects; keep them clear and well-maintained.

Knowing which pests are most active during winter helps homeowners stay alert.

rats and mice:
Seek shelter in lofts, kitchens, and basements.

cockroaches:
Thrive in warm, humid areas like kitchens and bathrooms.

Clothes moths:
Damage wool, silk, and other fabrics in wardrobes.

spiders:
Commonly move indoors to escape the cold.

silverfish:
Found in damp, dark areas like bathrooms and basements.
