    Are Human and Pet Fleas the Same?

    First off… are human fleas and pet fleas the same thing?

    Well… yes and no.

    There is technically a “human flea” that goes by the more scientific name, Pulex irritans.

    These fleas are not found in more industrialized first world countries like the United States, so it is more likely that your cat or dog has gotten fleas and you’re getting caught in the crossfire.

    Flea bites on humans can be caused by either dog fleas, cat fleas, or human fleas. Both cat and dog fleas favor drinking the blood of their canine and feline hosts.

    However, this doesn’t stop them from wandering around and grabbing human blood snack from time to time. Severe flea infestation also lead to both cat and dog fleas hunting for human hosts as their alternative source of food.

    On the other hand, the human flea (Pulex irritans​) usually comes from a wide variety of mammals such as coyotes, skunks, and foxes. ​​​When it comes to physical characteristics, the human fleas are pretty much the same to dog and cat fleas.

    Human fleas are however slightly larger in body size (1.5-4mm). Human fleas are also dreaded because they occasionally transmit pathogenic plagues such as Yersinia pestis, aka the plague (not good).

    ​How do Humans Get Fleas?

    More often than not, humans get fleas by coming in contact with their infested cat or dog. Below we listed out a couple more common ways humans manage to get onto a human host.

    • Pets: The obvious method of getting human fleas is if you have cats or dogs at home and have fleas that you are not aware of. It only takes one month or two for thousands of cat or dog fleas to reach your bedroom and take you for dinner and midnight snack.
    • Traveling: Even if you are not a pet owner, fleas can still invade your home in other ways. Visiting flea infested places can also trigger an infestation in your home. With  the help of their strong hind legs, fleas can easily jump into your luggage and hitch a free ride on you.
    • Farms: The human fleas, Pulex irritans, have also been recorded to live on pigs. This means that people who work on pig farms are prone to acquiring fleas.
    • Other Animals: Human fleas are also delivered straight into homes through other hosts such as birds and rats.

    What Are Common Signs Humans Have Fleas?

    Fleas primarily feed on the blood of their host. On average, our body is composed around 9-12 pints of blood.

    How Long Does It Take To Get Rid of Human Fleas?

    Provided that you are already equipped with the right knowledge and tools, getting rid of human fleas from your body takes only a couple of minutes.

    However, it covers only half of the problem. In fact, flea infestation is composed of 90% eggs and these things don’t settle in one place.

    This is why cleaning up infested areas is CRITICAL to complete removal.

    Flea eggs are not sticky and therefore fall to the ground most of the time. If you have fleas in your hair, chances are that at least a couple hundred eggs are scattered all over your home, especially in your bedroom near your pillow.

    The sooner you vacuum up all potentially infested, wash all of your sheets (on high-heat), and treat your pets, the sooner your problem should take care of itself.

    Final Thoughts On Human Fleas

    More likely than not, if you are a man or a women, and you think you have fleas, it is probably becuase you caught them from your pets.

    If a flea has gone without a blood meal for a long period of time, they will search for whatever they can find.
