Can Humans Have Fleas?

Fleas are small wingless insects that are usually about one-tenth of an inch long. Their bodies are flat and dark brown and have mouth parts that can pierce the skin and feed on blood. Regardless of the host, fleas are considered pests. Their bites can cause itching, swelling, and raised skin. These bites typically appear in clusters or rows. They can remain itchy for several weeks.

Fleas live in the fur of pets. They will jump from one animal to another, including humans. Fleas can infest a home after eating an animal, so you need to be vigilant in removing fleas from your home. Once you have a flea infestation, you must eliminate both adults and eggs. The eggs will be more difficult to remove than the adults, so be sure to thoroughly clean your home.

Fleas cause itching because their saliva contains an anticoagulant that increases blood flow. As a result, fleas trigger an immune reaction, causing skin to swell and redden. These reactions can be painful and may lead to an infection. It is important to seek medical care if you notice a flea infestation.

Fleas are most common in pets, but humans can also be infected. Fleas may infest your home within a month of exposure to an infected animal. Fleas are particularly common on farms. Pigs are known to attract human fleas, and can cause them to infest your home.
