Some flea facts: The most common species is the cat flea, which often feasts on cats, dogs and humans. Fleas do not fly. Instead, they jump from one place to another. In fact, fleas can jump as high as 8” vertically, which is 150 times their own height.
Adult fleas use that fast jump to get away from danger, but also to leap onto their furry or feathered hosts. Once they're aboard, fleas use their sharp tube-shaped proboscis, called a stylet, to pierce the skin and suck the host's blood.
Fleas can jump onto you from your dog. However, most fleas don't prefer to live on humans because humans don't provide them with the right shelter or food source. Fleas may bite you, but they'll typically jump off you after a short time. You don't have to worry about them trying to live in your hair.
Pleural arch size and jumping ability are often correlated. In flea species that are poor jumpers, the pleural arch and resilin are missing or diminished. However, even without the booster mechanism, they're able to make small leaps with the muscular system of their legs.
Can Fleas Live in Your Bed? These pests infest multiple areas in homes, especially mattresses, cushions, and carpeting. Pets transfer fleas to the beds and furniture where they sleep. From here, the insects quickly spread around the house.

Can you feel a flea crawling on you?
Fleas are tiny and agile insects, making it challenging to feel them crawling on the body, particularly if there are only a few present. However, a persistent itching or a prickling sensation on the skin, especially in areas such as the ankles, legs, and waist, may indicate the presence of fleas and their bites.
In addition to the chemical makeup, other people believe that fleas are simply attracted to some scents more than others. This is why they might prefer a certain individual due to their natural body scent, sweat, and/or the products they apply to their skin, such as soaps, shower gels, deodorants, etc.
During the day, fleas avoid the sun so they are most active at sunset and least active at sunrise. At dusk, the pests would lay more eggs, respire more, and move around in the yard more. Although the fleas are not completely inactive at any time of the day, they have increased activity at dusk and night.
Fleas have flattened bodies so they can move through the fur of their hosts easily. They also have very strong exoskeletons, making them very hard to crush. They also leap out of danger quickly and are very small, so if they do get away they are hard to find again.
The common cat flea, which infests dogs, cats, and other mammals, often complete their life cycle on or very near their host. But fleas do not usually live on humans. They jump on for a quick bite, then jump back off to seek better living conditions.
Clothing provides no nourishment to them, so they're not going to hang on a piece of material for long. These pets know that they need a warm-blooded host to get fed, so they will find one as soon as possible. Though they might jump on your pants or shirt, they won't stay on there for more than 24 hours.
Fleas can hitch a ride inside on articles of clothing, and can also be carried on the backs of animals, such as bats, raccoons, opossums, rats, and/or squirrels.
While fleas don't have wings, they are able to catapult themselves 40 to 100 times their body length in distance and up to 2 feet in height. To say this is an impressive feat of athleticism would be an understatement.
Enquiries relating to suspected flea infestations have increased by 47% in a year, according to recent data from Rentokil Pest control, and the experts believe the unusual weather in 2023 could be the reason.
To protect yourself from fleas: Use Environmental Protection Agency (EPA)-registered insect repellents containing DEET, picaridin, IR3535, Oil of Lemon Eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone. EPA's helpful search tool can help you find the product that best suits your needs.
Studies suggest that fleas do not prefer certain blood types in the way that some other parasitic insects do. Instead, fleas are more opportunistic, looking for the most accessible and abundant food source rather than a specific blood type.
While fleas can technically lay eggs on our scalp, the possibility of this happening is extremely rare. Given how much these small parasites can disrupt a household, however, knowing all you can about fleas can help you avoid an infestation or manage an existing flea problem.

The first sign of fleas in your bed may be waking up with itchy bites on your skin. If fleas fall off a pet and land in the bed, they may bite humans if the pet is not nearby.
