Flea adults suck the blood of animals and people; while larvae feed on adult’s feces, containing partially digested blood.
Larvae can also feed on organic matter, but will not develop without the adult’s feces diet.
Adult fleas begin searching for food as soon as they emerge from the pupal stage.
Fleas only have about a week to find their first blood meal. After that, they can survive for several years without food.
Fleas need a blood meal in order to be able to reproduce.
A female flea can consume 15 times her body weight in blood on a daily basis.
