Fleas are parasites that feed on the blood of both mammals and birds. At a length of 1/12″ to 1/8″ long, fleas can be hard to see and therefore difficult to realize you have an infestation until it’s already there. Fleas are wingless, oval, flat and dark reddish-brown in color. They have 6 long legs and can jump up to 200 times their body length. The most common species of flea in the United States is the cat flea (Ctenocephalides felis) which, ironically, can also be found on dogs!

Flea bites on humans appear as small red spots that usually occur in groups or clusters of 2 or 3 with redness surrounding them. Other symptoms include itching, hives, rash, and swelling around the site of the bite. Fleas commonly bite around the feet, ankles, and lower legs, although they can bite other places, as well. Those who have allergies to fleas can also experience shortness of breath, wheezing, swelling of the lips and tongue, dizziness, nausea, and chest pain. Scratching flea bites can also leave open wounds, allowing bacteria to invade causing infections.

One question that many ask is are fleas dangerous to humans. The answer is yes. Fleas are known to transmit several serious diseases including plague, bartonellosis, typhus, tungiasis, and flea tapeworm.

Flea bites can be itchy, painful, and downright aggravating. If you fall victim to a flea invasion, consider these natural do-it-yourself remedies for flea bites.
