As we move into December, thoughts turn to festive preparations, colder days, and cosy nights indoors. But while we’re keeping warm, so are a whole host of unwanted guests — and pest activity doesn’t stop just because the holidays are approaching.
At ASW Pest Control, we often see a change in pest behaviour at this time of year. Rats and mice are more determined than ever to get indoors, while insects and stored product pests can become a problem in kitchens, shops, and food preparation areas. Whether you’re at home for Christmas or managing a busy business in the run-up to year-end, here’s what to watch for in December.
Rodents: Still the Biggest Winter Threat
By December, rats and mice are well and truly settled in for winter. With natural shelter and food sources depleted outside, they’ll make full use of any gaps or access points to get indoors. Lofts, wall cavities, basements, garages and even commercial stockrooms all offer the warmth and shelter rodents are after.
Signs to look out for:
- Scratching or scurrying noises (especially at night)
- Droppings under sinks, behind appliances or along skirting
- Gnaw marks on wires, packaging, or wooden fixtures
- Musty smells or shredded nesting materials
At this time of year, rodents can cause major issues, from damage to wiring and insulation to contamination of food prep areas — and in commercial settings, the impact on reputation and compliance can be serious.
Insects Don’t Disappear Completely
While insect activity naturally slows in colder weather, some pests remain active indoors — especially in heated homes, warehouses, and food environments. Stored product pests like biscuit beetles and flour moths may be drawn to seasonal treats and dried goods. And cluster flies, which entered loft spaces earlier in the autumn, may start to become visible on sunnier days as they stir in the warmth.
In homes, we also occasionally see activity from silverfish, spiders, and cockroaches in damp areas like bathrooms, kitchens, or under sinks.
Festive Triggers for Pests
December is a time for decorations, parties, and deliveries — all of which can unknowingly help pests find a way inside. Here are a few seasonal pest triggers to be aware of:
- Christmas trees and wreaths can harbour insects (especially if stored outdoors)
- Increased food waste over the festive season can attract rats and flies
- Boxes and deliveries offer temporary shelter for pests and may bring them in
- Garages and lofts disturbed for decorations can reveal existing infestations
