One word of caution, though. While fleas rarely take up residence on human skin, they can and will live happily in a human home with no pets present. If fleas find their way into your house and don't find a dog, cat, or bunny on which to feed, they will use you as the next best thing.he good news is fleas don't live on people (literally on our bodies), with very few exceptions. Human fleas (Pulex irritans) prefer to feed on humans or pigs, but these parasites are very uncommon in homes and more often associated with wildlife.

With ample food supply, the adult flea will often live up to 100 days.Newly emerged adult fleas live only about one week if a blood meal is not obtained.enerally speaking, an adult flea only lives for 2 or 3 months.
