Pulex irritans is known as the human flea. Fleas are 1-4 mm in length and laterally-compressed. They lack both genal and pronotal combs (ctenidia) and the ocular setae are below the eye.
Fleas are tiny, wingless insects. They are dark brown or black and have flat bodies. They have six legs, strong claws on the bottoms of their legs that allow them to hold onto a host and mouthparts that pierce your skin and feed on your blood.
We get three types of flea in the UK. The most common is the cat flea Ctenocephalides felis. Less often, we get dog fleas Ctenocephalides canis. While rare, we do occasionally get human flea Pulex irritans infestations.
If fleas were human-sized, they would not be able to jump as high relative to their increased size. This is because the flea's jumping ability is due to its small size and powerful leg muscles, which allow it to propel itself much higher relative to its body size than larger animals can.

When fleas impact humans, they may flock to the eyelashes, the eyebrows, the head, and the pubic region. Hair loss may occur on the body where the fleas are located. If the infestation is severe, anemia may occur as a result of the blood that is lost while the fleas are feeding.
Fleas are tiny and fast-moving, so you may not always feel them. When they bite, they inject saliva, which can cause an itchy sensation. Some people may not react to flea bites at all, while others might feel a tickling or crawling sensation in areas with thin skin.
Human fleas are now less common in the UK, except for farming areas where they can survive on pigs, and then jump to humans. They will bite anywhere on the body and are associated with itchiness as fleas crawl over the skin.

Can Vacuuming Kill Fleas? Can Vacuuming Kill Fleas? According to extensive studies conducted at Ohio State University, vacuuming is indeed an effective way of getting rid of fleas! Through these studies, scientists discovered that vacuuming killed 96% of adult fleas from carpets and 100% of the flea pupae and larvae.
Who are fleas attracted to? Fleas are attracted to light, movement, heat, and CO2 that their hosts exhale when breathing. Fleas will jump slightly any time one of these signals triggers movement, but flea activity really takes off when the presence of multiple attractants are noticed.
Generally speaking, though, an adult flea only lives for 2 or 3 months. Without a host for food, a flea's life might be as short as a few days. But with ample food supply, the adult flea will often live up to 100 days.
Rentokil Pest Control published this scary statistic and experts currently believe that it could be down to 2023's peculiar weather.

You might be asking yourself will fleas eventually go away? While some could last 2 – 3 weeks, they could also live for up to 12 months on the host it finds, so it is unlikely they will go away on their own. Fleas can also reproduce very quickly by laying eggs in carpet, bedding, or garden prolonging the infestation.
Pets out in the wild, in tall grass and in the wilderness can end up with fleas. Fleas cannot fly as they do not have wings, but they can jump many times longer than their own body length. Thus, they are able to jump onto a passing animal or human and latch on their body hair and skin.

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.
