What Determines a Mosquito’s Lifespan

Assigning a specific timeline to a mosquito’s life is hard. Generally, male mosquitoes live an average of seven days, while the females can live between 48 and 300 days. However, its species and other natural factors determine how long mosquitoes live.

Type of Food

Female mosquitoes need blood to nourish their eggs, but this is not their only source of food. Mosquitoes also feed on nectar, fruits, and other plants. As with different nutritional requirements, different species prefer different types of food. If the availability of the preferred source of food becomes suddenly limited, mosquitoes may starve before they are able to breed.

Availability of Food

Fertilized female mosquitoes can hibernate over the winter, while the males die off. Females need to have a change of diet and gain weight before they settle in for the non-developmental diapause (hibernation) period.

Female mosquitoes will eat extra sugars to increase their fat body content. This means they will not need to feed again until spring. Late in the season, they will stop searching for blood and instead seek out nectar and decomposing fruit. If there are any adequate food sources available, female mosquitoes will die while attempting to diapause.


Mosquitoes cannot breed in very low temperatures. However, as temperatures climb higher, their activity also declines. Mosquitoes bite less when it becomes excessively hot, as it poses the danger of dehydration and death.

If temperatures drop below 50 degrees, it becomes hard for the mosquitoes to move around and search for food. Without long periods of feeding, they become unable to breed and will die. If the eggs are not fertilized or adequately nourished during this period, or the adults die, there will be no offspring for that generation.


Some species have evolved so that their breeding preference is limited to contained water. This selective breeding affects their lifespan because if they lack their preferred conditions, then breeding will not take place, stunting reproduction.

Consequently, where standing water is already present, rainfall will disrupt any eggs that have already been laid. This can negatively affect their chances of survival. However, once the rainfall period passes, the resulting puddles can give rise to an increase in the local mosquito population.

Keep Mosquitoes Away Their Entire Lifespan

Although knowing what determines how long a mosquito will life is useful information to us, it shouldn’t have to be to you. Whether they live for a week or an entire year, you won’t have to concern yourself with these pests when you contact us and invest in mosquito prevention services.
