How Big Are Fleas on Humans?
WouterFleas are small insects that live in and on warm-blooded animals, including humans. They do not prefer to feed on humans, but will bite them on the lower body. They have six legs, not including wings, and their hind legs are longer than their forelegs. This allows them to jump as high as eight inches and can even reach a maximum height of 16 inches. Flea bites are extremely itchy and can last for weeks.
Fleas are brown and flat, and they have six legs and are easily visible with the naked eye. Fleas live in warm, moist areas and burrow through animal hair and skin to feed. Fleas are between 1.5mm and 4mm long and have a long, wingless body. Female fleas are slightly larger than males and can grow to be as large as 2.5mm in length. They can also jump over the diameter of a football field!
The lifespan of a flea depends on the species. Most species of fleas live in different stages of development. The egg stage is tiny (about one eighth of an inch), and the larva stage is smaller (about one eighth of an inch). Pupae, on the other hand, are tiny (about three millimeters long). The larvae feed on the blood of the host and produce fecal matter.
Adult fleas are a wingless insect about one-tenth of an inch long, with six long legs. They often appear in clusters of three or four. Adult fleas do not cause a reaction on humans, but if they live in a household with several members, the fleas might select one member as the first target for feeding.
