Which Animals Have Fleas?

Fleas are parasitic insects that live in the skin of animals. Although they are most common on dogs, cats and rodents, they can also infect humans. They are often spread accidentally by humans playing with infected pets. There are over 20 species of fleas in the world, including the deadly B. anatum, which is the most common.

The life cycle of fleas is characterized by three stages: egg, larva, and pupa. Each stage has its own specific requirements, but the life cycle usually lasts about two to three weeks. In the third instar, the larva spins a silk cocoon made of grains of sand and debris. This cocoon is used as a camouflage for the pupa. After the pupa develops into an adult, it emerges almost colourless and feeds several times a day. They also use dried blood-rich feces as food.

Infested animals can be seriously injured or even die from flea bites. Fleas can transmit a variety of diseases, including tularemia and cat-scratch disease. Humans are unlikely to be infected with these diseases, but flea bites can be a nuisance.

Fleas spend most of their lives on animals, usually cats and dogs. They feed and reproduce while attached to their host. In areas with low humidity, they are likely to remain on their host for several months. While the adult fleas live, they will lay eggs on the host, most often on the pet’s bedding.
