Fleas do not have a narrow specificity. They go from one animal to another, attack a person, although they prefer to eat on warm-blooded "their" kind.
The appearance of the parasite is as follows: a small black or dark brown body, covered with chitinous scutes. Chitinous cover is very durable and protects the insect from mechanical damage. The parasite has a small size - from 0.5 to 3 mm, so it is difficult to consider, and sometimes you can not even notice. The wings of these insects atrophied, they move around the body of the owner with the help of tenacious paws, can make jumps for a considerable distance - up to one and a half meters.
These insects are not constantly on the body of the host. They can live in bedding, carpets, upholstered furniture, in earth and sand, nest material and burrows. Parasites lay eggs, from which larvae hatch. Larvae live in an external environment and feed on dead organics. After several lines, the larva pupates and an adult flea appears on the light. She attacks the new master. It should be noted that the parasite can exist without food for up to a year and a half.
