In BC, several pests become significantly more active indoors during the colder months as they seek warmth, shelter, and food. Understanding which pests to watch for in winter — and what the early signs look like — means you can act before a minor issue becomes a major infestation.

Rats and Mice

Norway rats and house mice are BC’s most active winter pests. They enter through gaps around pipes, vents, and foundations as temperatures drop. See our signs of a rat infestation guide and our mouse pest control BC page.

Cockroaches

German cockroaches breed year-round in heated kitchens and bathrooms. Winter doesn’t slow them down. See our cockroaches pest control BC guide.

Bed Bugs

Bed bugs are active year-round in heated homes. Winter travel increases the risk of introducing them. See our complete bed bugs BC guide.

Silverfish

Silverfish thrive in warm, humid indoor spaces in winter — particularly basements and bathrooms.

Spiders

Spiders enter BC homes in autumn and remain active indoors throughout winter. See our spider control BC page for professional treatment.
