While they do thrive in warm weather, some mosquitoes in Utah can survive through the winter months. The University of Utah advises that there are more than 50 species throughout the area and their ability to hibernate depends on the type. Some die at the end of the season, while others burrow underground when the weather gets colder. One of the most common ways for them to survive is through their eggs.
Mosquitoes either bury their eggs or leave them in standing water, where they remain dormant in the cold. Once the water begins to warm with the change in season, they begin to hatch. In this way, a female mosquito on your property now can leave behind eggs that contribute to infestations the following year.
