Urban Myth: Pest Insects Die Off in the Winter

Ah, winter. The weather is colder and that means no batting away wasps or flies swarming around your bins. So what happens to pest insects in winter, do they die off?

The short answer is no. Many of them find their way indoors to shelter over the winter months or they find other ways to survive until spring.

What happens to pest insects in the winter then?

Some insects like beetles and wasps enter something known as ‘diapause,’ a type of hibernation where they literally freeze in wait for the spring. Metabolism and heart rate slows down, their temperature drops, and they become inactive. Then come the spring, they thaw out and become active again.

There are some pest insects that don’t survive the winter. Mosquitoes are one of them. For this reason, the females lay eggs in the late summer and these survive until the spring when they are ready to hatch.

Where do some common pest insects go in the winter?

Cockroaches

Cockroaches head indoors where it’s damp and warm, and they’ll look for shelter in homes, restaurants, and pretty much anywhere they can find a source of food.

Ants

Ants adapt really well to cold weather. Their body temperature drops and their movements slow down to conserve energy. They tend to hide out in their colonies, deep in the soil. You’ll also find them hiding out under logs or the mulch in your compost heap. Once spring comes, they’ll be ready to search for food and invade your home once more.

Spiders

We all know that these pest insects like to venture inside during the colder months to find food, shelter, and a mate. You’ll often find them in undisturbed places like garages, basements, attics, inside of boxes, and underneath furniture that’s not often moved.

Some spiders can survive outside however, and they will hibernate under piles of leaves, rocks, or in other sheltered spots.
