It's a common misconception that pests disappear in winter. While some activity slows down, several pests remain active — and some even move indoors seeking warmth.
Rodents are the biggest winter concern. Rats and mice that were outside in autumn now seek shelter in roof voids, wall cavities and subfloors. If you hear scratching or scurrying at night, you likely have unwelcome guests.
Cockroaches, particularly German cockroaches, remain active year-round because they live indoors. Kitchens with warmth, moisture and food are perfect habitats. A winter sighting often signals a larger hidden population.
Silverfish also thrive in winter, taking advantage of damp, undisturbed areas like bathrooms, laundries and roof voids. They damage books, paper and fabrics.
A winter General Pest Treatment is just as valuable as a summer one — it targets the pests that have moved indoors and establishes a protective barrier before spring activity ramps up.
