Can Fleas Reproduce on Human Blood?

One of the most frustrating things about fleas is the fact that they cannot reproduce on human blood. Despite their instinct to bite humans, fleas prefer to feed on animal blood. If a flea does not get a blood meal, it can go up to 100 days without laying eggs. The population of fleas would quickly decrease if they could not lay eggs. When they do get a blood meal, they will lay eggs almost immediately or within a few days.

Fleas lay eggs, which are half a millimeter in diameter. These eggs are white and ovular. Once fertilized, the adult flea will lay two to fourteen eggs a day. This means that the adult flea can lay up to 800 eggs in her lifetime. These eggs are usually laid on the skin or hair of the host. They may lie dormant for a long time, but will hatch when they sense a vibration or heat from their host.

Fleas are known to live on many different types of animals. The most common fleas are those that live on animals with fur or feathers. They are particularly attracted to feathers, which make them an ideal nest for fleas. They can even lay eggs within the feathers, making them a perfect breeding ground.
