Why Mosquito need blood
Both male and female feed mainly on fruit and plant nectar, but the female also needs the protein in blood to help her eggs develop. Once she's had her fill of blood, she'll rest for a couple of days before laying her eggs. They choose their targets through a combination of smell, heat and visual cues, and continue seeking bloodmeals until their abdomens are full. The females can live up to about a month and feed every two or three nights during that time.
