Human flea

The human flea is a single species of 2000 species of fleas in the world. This flea is scientifically called “Pulex Irritans”.

This is especially observed in humans who live in tropical and temperate climates.

Human fleas, exactly like other insects, have special physical characteristics and particular behavior.

Physical characteristics

  • The lifecycle of a flea is so easy, it starts with an egg, then a larva, then a pupa and ends with an adult mature flea ready for mating and reproduction.
  • Human fleas and pet fleas are mostly similar, a single male human flea is 2.5mm long and a female is 3.5mm due to the long abdomen used for carrying the huge number of eggs (up to 400 eggs).
  • Generally, human fleas are brownish red little beings with 6 legs and mouth mandible used for biting and sucking.
  • Pulex Irritans are wingless and they have a compressed body which gives them the shape of a grain of wheat.

Behavioral characteristics

  • Human flea’s behavior is not really special. They are not as socialized as other types of insects which build their own nest and form colonies in the infected location. Human fleas just move from a nest to another when it is not comfortable anymore.
  • Human fleas live around 12 weeks: after the first 4 weeks, the larva leaves the nest in research of warm-blooded victims.
  • Human fleas like to live in warmth and shelter, with an appropriate food source near to the nest which is commonly human hair of pet fur. For that, they will invade your body as soon as they find a way to settle on your head, in your armpits or even in other hairy places.
  • Human fleas are different from lice, but they have the same food: blood, whether it is human or animal, they just love to feed on blood.
  • Fleas bite the human skin to reach blood and it can cause many diseases as these insects carry viruses and microbes.
