How Long Do Fleas Die Without Food?

The lifespan of fleas without food varies depending on their life cycle stage and their host’s environment. While fleas are usually found feeding on animals, they will often attach to humans if the animal is not available. Fleas can live for several months without blood feeding if the environment is warm and humid.

Fleas can live for weeks without food, although some species are able to live for several months. Young adult fleas are able to survive without a host, as they do not develop a blood dependency. Adult fleas, however, can survive for up to two weeks without a host and can live up to six months in pupae.

If you notice fleas in your home, one of the best ways to kill them is to bathe your pet in warm water. Salt is a natural ingredient that kills fleas, but to kill them, you must process it to make it ultra-fine. To do this, use a food processor or blender and run the machine until the salt is completely fine and resembles talcum powder. This process may take up to 20 minutes.

Adult fleas cannot live on humans for a long time, and they usually only bite once or twice. They are only interested in humans if they cannot find food. Their preferred hosts are animals, but pet owners are often the hardest hit.
