As the temperature drops and we move deeper into the winter months, pests begin to look for warmth, shelter, and food—often finding their way into homes across Scotland. While summer may bring more visible pest activity, winter is a key time for infestations to take hold behind the scenes. Rodents, spiders, and insects can all pose problems if they’re not kept in check.
Knowing what to look out for—and how to prevent pests from settling in—is the best way to keep your home protected during the colder months.
Common Winter Pests in Scotland
-
Rats and Mice
These are the most common winter invaders. They seek out warm, quiet spaces like lofts, basements, wall cavities, and behind kitchen units. Once inside, they can cause damage by chewing through wires, wood, and insulation—and they pose serious hygiene risks. -
Spiders
Although mostly harmless, many people find spiders unwelcome guests. They often enter homes to escape the cold and find quiet, dark corners to hide in. -
Cluster Flies
As the name suggests, these flies gather in large numbers—usually in loft spaces or window frames—seeking shelter during the winter. If disturbed, they can become a major nuisance. -
Cockroaches
They favour warm, damp areas such as boiler cupboards, kitchens and bathrooms. While less active in colder months, once they’re indoors, they can thrive.
Winter Pest Prevention Tips
-
Seal Entry Points: Check for gaps around pipes, vents, windows, and doors. Even the smallest opening is enough for a mouse to squeeze through.
-
Keep It Clean: Food crumbs, bin spills, and standing water can all attract pests. Keep kitchens clean and store food in sealed containers.
-
Declutter Storage Areas: Rodents love quiet, undisturbed places filled with boxes or fabric. Keep storage spaces tidy and off the ground.
-
Check Your Loft and Basement: These are common hiding spots during winter—look for signs like droppings, gnaw marks, or shredded materials.
-
Call in the Professionals: Prevention is important, but if pests are already inside, expert treatment is the fastest and most effective solution.
