People are being reminded to stay alert for pests seeking warmth and shelter as the temperatures drop.

Pest control provider Rentokil has warned that common festive preparations like retrieving decorations from the attic can provide entry points for unwanted visitors.

Cluster flies are often found in attics in large numbers, and old bird nests may be discovered, which can block vents in roof spaces, as well as harbour mites.

Rats and mice are drawn to food sources and warm spaces, and can chew through wires, insulation and stored decorations.

The company recorded a 12 per cent increase in rat-related enquiries for the first nine months of 2025 compared to the same time last year.

Rentokil has the following Christmas pest-proofing tips:

• Check decoration boxes before bringing them indoors: Open them outside first and look for signs of insects or rodents, such as droppings, nesting material, or gnaw marks.
• Inspect Christmas trees: Both real and artificial trees can harbour insects or eggs.
• Avoid edible decorations: Swap food-based items like gingerbread or candy canes for non-edible alternatives.
• Keep clutter to a minimum: Dispose of wrapping paper, packaging, and unused items promptly to reduce hiding spots.
• Inspect attics and storage areas: Watch for signs of pest activity, including droppings, nests or damage.
