Can Fleas Be Contagious?

Fleas are tiny reddish-brown insects that live on the surface of the human body. They are about a quarter of an inch long, have small wings and large back legs, and can jump up to 12 inches. Their bodies are flat and covered in spines to help them navigate the hair shafts of their host.

Adult fleas can live for several months without feeding. They feed by biting the skin of the host with their saw-like mandibles. Their saliva contains anticoagulants and promotes blood flow. After feeding, the female flea will lay eggs. The eggs are oval-shaped and light in color. Flea larvae will hatch and form a cocoon within a few weeks.

If fleas are infesting your home, you should clean your pet’s bedding regularly. You should also regularly vacuum your carpets and furniture. Always remember to empty your vacuum before reusing it to avoid reinfestation. If the fleas remain, you can treat them with an effective flea spray.

Fleas can be contagious to humans. They can be carried into your home on other animals, and they can also hop from one pet to another. Fleas can also be transferred to humans through clothing and bags.
