How Cold Can Mosquitoes Survive?

Depending on the mosquito species, some can survive the cold. In fact, many species can overwinter in a variety of environments. Some can even stay in ice and snow. In the warmer months, mosquitoes tend to become less active. This can be caused by a lack of food. During the winter, some mosquitoes enter a dormant state called diapause.

During diapause, a mosquito’s metabolism slows down and it stores nutrients. Its body temperature decreases as well. It can survive for several months without food or water. It also develops a dormant state until the temperatures are warm enough to resume its normal life cycle.

When the temperatures are below 50 degrees Fahrenheit, most mosquitoes will hibernate. In some cases, they will die. But in most cases, they will survive. Some species will hibernate for six months or more.

Some female mosquitoes may lay up to 300 eggs at a time. The eggs can survive freezing temperatures. When the temperatures rise, they will emerge from the eggs. The larvae can then seek muddy bottoms of pools. They can also be found in moist soil.

Some mosquitoes hibernate in a dormant state in the attic or in crevices. Other species, such as the pitcher plant mosquito, stay buried in a leaf litter. They don’t bite humans, but they can still transmit diseases.

Those species that can survive in the cold will usually find a sheltered location to hibernate. Some will die from lack of food.
