Mosquitoes typically have a lifespan of under one month upon reaching adulthood, with females living longer than males. Lifespan is highly dependent on temperature and species, as some mosquito species hibernate, adding months to their adult life span even though they are inactive during this period.
Female mosquitoes live for two to three weeks on average but can survive for much longer under favorable conditions, such as the temperate interior of a garage. Male mosquitoes typically live about a week. Some species only live as long as the summer, when weather is warm, while others pupate into adulthood, reproduce and hibernate throughout the winter, emerging in the warmer weather to lay their eggs. Species such as Culex tarsalis have shorter life spans in warmer weather.
