Flea Facts & Information

Flea Overview

Fleas are tiny, wingless insects belonging to the order Siphonaptera, and they are notorious for their irritating and often blood-sucking habits. These minuscule pests have been a nuisance to humans and animals for centuries, with their bites causing itching, discomfort, and in some cases, transmitting diseases. Fleas are highly adaptable, with over 2,500 known species, and they can infest a wide range of hosts, including mammals, birds, and even some reptiles. Their powerful hind legs enable them to jump impressive distances relative to their size, allowing them to move quickly between hosts. Effective flea control involves both treating infested animals and their environment, as these resilient insects can lay hundreds of eggs in cracks and crevices, leading to persistent infestations if not properly managed.

What do Fleas Look Like?

Fleas are incredibly small, measuring only about 1 to 4 millimeters in length, depending on their life stage. They have a flattened, oval-shaped body, which is covered in a tough exoskeleton that helps protect them. Their coloration can vary but is typically reddish-brown to dark brown, which allows them to blend in with the fur or feathers of their hosts. Fleas possess powerful, long hind legs that are perfectly adapted for jumping. These legs are equipped with specialized structures that act like miniature springs, enabling fleas to leap remarkable distances relative to their size. Their mouthparts are adapted for piercing and sucking, allowing them to feed on the blood of their host. Overall, fleas have a distinctive appearance, with their flattened body, reddish-brown color, and unique jumping ability making them easily recognizable to those who have encountered them.
