How Long Do Fleas Last on Humans?
WouterThe life cycle of fleas is short and can last anywhere from seventeen to twenty-six days on humans. Flea eggs hatch after a few hours and remain on the host for about 17 to twenty-six days. Adult fleas will die after this period because they will starve to death if they don’t find a host. However, the eggs remain quiescent for up to five months in an environment that mimics the host. You can kill the fleas by vacuuming the home often to simulate the host cues and force the adult fleas to emerge.
Vacuuming frequently is one of the best ways to kill fleas and prevent their eggs from hatching. Fleas develop in carpeting, so vacuuming your home regularly will help speed up the process. Flea bites cause an initial reaction called a wheal, which is not that itchy. Over time, it turns into a papule and then a welt.
Fleas’ eggs are non-sticky, but the larvae attach to fabrics or silk-like threads. Flea eggs do not live without an animal host, so they fall into your home and can be found on bedding. A flea infestation will be difficult to control once the adult fleas emerge.
Fleas are more active at night, but they are present all day. The fleas emerge from their cocoons when they feel heat or pressure. Walking around carpets or other areas with high foot traffic can cause fleas to emerge. To protect yourself from fleas, wear long white socks when outdoors. This will prevent them from attaching to your skin and make it easier for you to identify them.
