The 2,500 species of tiny, flightless insects commonly known by the term fleas live as external parasites of animals and birds. The blood of their victims is what fleas consume to survive. Fleas may pass through their hosts’ fur or feathers thanks to their “flattened” sideways or thin bodies, around 3 millimeters in length. They are often brown in appearance. Their rear legs are incredibly well suited for leaping, yet they lack wings. Their mouthparts are designed for piercing flesh and sucking blood, while their claws prevent them from being moved. They can leap 50 times higher as compared to their body length.
Flea removal may be a difficult and expensive process. Fleas attack both people and pets, unlike the majority of home pests. A hypersensitive animal will frequently need veterinary care due to the bites’ potential for severe itching and discomfort. Additionally, tapeworms and bacterial diseases can be spread by fleas.
