In the warm summer months, insects are often buzzing around our heads, circling our picnic tables, and hovering around our ankles. However, as winter settles in, insects seem to slowly disappear. The question is: where do they go?
Most insects manage to survive, although they all survive winter in different ways. Some insects survive as eggs, some insects survive as larvae, and some insects survive just as they are, and some insects don’t survive at all.
Many Insects Travel
Many insects survive the cold by doing whatever they can to escape it. Many butterflies and dragonflies migrate south when cool weather approaches, similar to how people often vacation in winter months. North American Monarch Butterflies actually travel to Central Mexico each winter to seek out warmer temperatures, traveling many miles to get there. Some insects travel underground. A variety of aquatic insects choose to spend winter at the bottom of ponds. The water does not freeze at the bottom and they can remain warm. Other insects burrow deep into soil, far under the frost.
Many Insects Stay Put
While many insects do put a plan of action into place as temperatures start to drop, other insects don’t do anything at all. Some insects just continue to live as they always have. These insects often burrow into the snow in search of a warm place next to a leaf or a patch of grass. Some insects just linger and rest on the surface of snow. These insects manage to survive the winter and are very much alive throughout the season. Other insects seek shelter, such as our home, and spend the winter months there unless we discover them.
Many Insects Freeze
Many insects go into something referred to as “diapause.” Diapause is when an insect remains dormant in a semi-frozen state until it is able to thaw out in the spring. This survival method is a bit rarer than the others, but it is done. These insects survive freezing temperatures by essentially freezing themselves. These insects have a high concentration of glycerol in the blood which sort of serves as an antifreeze.
Many Insects Die
For many insects, the winter is a cold reminder that their life is coming to an end. Many insects die in winter months, leaving eggs behind. These eggs replace the old insects with a new generation in the spring. Many insects, such as crickets, lay eggs in the soil around winter time and die out and then those eggs hatch in the spring replacing the previous cricket population.
All insects do a variety of things to survive the winter and some do not survive at all. If you face a pest problem this winter, contact Comfort Pest Control and we can take care of it.
