Where do insects go in fall?

When September starts to ease in we see less insects crawling about. A lot of species are eagerly looking for a place to hide-out for the winter. It’s a welcome change from the overpopulation of summer. Different bugs have alternate ways of seeing through the colder weather.


Some insects go in search of warmer climates. The Monarch Butterfly is the best example where they fly south in the fall. Winter climates in the north can kill many bug species.

Overwintering as Larvae.

Immature larvae is one way insects pass by the winter. Heavy covers of leaf litter or similar shelters protect bugs from the climate. Some insects replace water in their body with glycerol which is a type of antifreeze.

Overwintering as Nymphs.

Dragonflies, mayflies and stoneflies live in pond water and streams. During the winter they’ll become nymphs and live under the ice. They live relatively normal lives regularly feeding. Emerging as adults in early spring.

Overwintering as Eggs.

Very few insects avoid the snow and ice as eggs. But, it’s a good strategy for Praying Mantis and Corn Rootworms.

Overwintering as Pupae.

The pupal stage is a safe place for some insects to wait away the winter. In the spring they will emerge as adults. Species such as moths, silkworms and Saturniidae can be found hanging from plant branches as pupae.

Adult Hibernation.

As grown-ups insects hibernate. Tree holes, leaf litter or under logs are common hiding spots for overwintering bugs. They’re able to survive only when temperatures are stable. Many species establish micro-habits during winter to live comfortably. Insects that hibernate have their growth, development and activities temporarily suspended. They go into a dormant condition called diapause.

Port Elgin insect control.

During the fall we see mass numbers of insects flying around trying to find a place to hide. Many of them can survive winter in an area with consistent temperature. This can be your home. If you find evidence of an insect infestation contact Truly Nolen.
