HOW TO IDENTIFY HUMAN FLEAS
Human fleas should not be judged on the basis of their name because unlike it, they have varied hosts to feed on. Like all the other fleas that feed on animals and hide in their fur and hair, human fleas also hide in human hair. They do not bite on the head; they bite on arms and legs instead.
The bites of a human flea can easily be identified by its structure. Unlike other fleas, human fleas leave many bites in the same area that indicates their presence. Human fleas can also be identified by noticing a few symptoms like itching in the head.
They are almost identical to all the other fleas. They are dark brown or black in color and have a laterally flattened body. They are wingless and use their long legs to jump on the hosts. They are 1 to 4 mm in size which makes their presence hard to be noticed.
The life cycle of a human flea includes four stages of development. The first stage is the egg. As an egg, it is oval-shaped, white, and 0.5 mm in size. The second stage is the larva. As a larva, it is creamy-white or sometimes yellow in color, and 0.6 mm in size.
The third stage is the pupa. As a pupa, it increases and become 4 x 2 mm in size. The fourth stage is the adult. As an adult, it becomes reddish brown in color and varies from 1.5 to 4 mm in size. They feed on warm blood for survival either from a human host or any other suitable host.
Human fleas can be identified by some of the symptoms of their bites on humans. They are-
Discomfort and itching– A human flea bite can lead to itchiness which can cause a lot of discomforts depending on the affected area.
Red bumps– A human flea bite can cause red bumps on the bitten areas which can be easily felt and seen.
