Yes, mosquitoes can survive without blood. While female mosquitoes need a blood meal to produce eggs, both male and female mosquitoes can survive for a period of time without it.
Mosquito Lifespan and Blood Meals
- Female Mosquitoes: Only female mosquitoes bite and feed on blood. This blood meal is essential for egg production. However, they can survive for several days, or even weeks under ideal conditions, without a blood meal. The exact time varies based on factors like species, temperature, and available nectar sources.

- Male Mosquitoes: Male mosquitoes do not feed on blood. They primarily feed on plant nectar and can survive for around 6 to 7 days on average. [Source: Vdci.net]
Nutritional Needs of Mosquitoes
Mosquitoes require both sugar and protein for survival.
- Sugar: Plant nectar provides essential sugars necessary for energy and basic survival for both male and female mosquitoes. [Source: ScienceDirect, My Heron Home, and Terminix]
- Protein (from blood): Female mosquitoes need the protein from blood to produce eggs. Without a blood meal, they will not reproduce, but they can still survive for a time. [Source: CDC, Mosquito Joe, and Terminix]
Survival Time Without Blood
- The provided sources state that even without blood, mosquitoes will typically live for about two to three weeks, or longer under ideal conditions. This is true for both male and female mosquitoes, though females will not be able to lay eggs without a blood meal. [Source: MandM Pest Control]
In summary, while blood is crucial for female mosquito reproduction, both male and female mosquitoes can survive for a considerable period solely on plant nectar.
