Why Fleas Bite Humans
WouterThe reason why fleas bite humans is not fully understood. Although fleas prefer other mammals for their primary host, they do occasionally bite humans. Their mouth parts, which pierce the skin and stab blood vessels, are designed to feed on human blood. During the feeding process, salivary glands open and inject an anticoagulant that keeps the blood flowing.
If you find fleas in your home, you should contact a licensed pest control operator to help you eliminate them. A licensed professional can assess the type of infestation and use registered insecticides to kill fleas. You should also practice good hygiene habits to reduce the risk of future infestations.
Most flea bites are small, red bumps on the skin. Unlike bedbugs, fleas do not anesthetize their wounds, so they can quickly attack a human’s skin. If you feel a bite on your skin, you may immediately swat it off.
You can also apply an antihistamine to reduce the itching from flea bites. Honey contains an enzyme called catalase that provides temporary relief from minor inflammation. If you can get hold of some unprocessed honey, you can lightly apply it to the affected area. Then, cover it with a bandage to prevent a sticky mess.
Fleas bite humans because they can transmit diseases. In the 14th century, fleas carried the deadly Yersinia pestis bacterium that killed over twenty million people. This disease is still present in parts of the United States, but it is treatable if caught in time. Another common disease transmitted by fleas is murine typhus.
