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.
The lifecycle of a flea. 5% of fleas live in the environment as an adult, 95 % of fleas live as eggs, larvae or pupae. For effective flea control it is essential to break the lifecycle in the environment. 1  Adult Fleas-jump onto your dog or cat, feed on its blood and then start laying eggs. Flea shampoo-kills fleas on your pet at the time of the bath, but once rinsed off have no lasting effect on fleas. 2  Rinses and sprays-vary in effectiveness, many need to be used weekly, some more often if severe flea problems are present.
