Unlike other insects, fleas can't fly, and adult fleas lack wings. While a flea's swift jump may look like they're taking flight, these pests can only hop around.
No, that's not wings they're using to move; it's the sheer power of their legs. These bugs are put into the categories of ants, silverfish, and grasshoppers. It's estimated that there are more than 2,000 species of fleas, but none of them have wings or the ability to fly.
Contrary to popular belief, fleas do not have wings. Of their six legs, the four in the front are much shorter than the two in the back. Fleas travel by crawling and jumping, and their long back legs enable them to jump up to 80 times their height and 200 times their body length.
Fleas mainly feed on non-human animals but can bite and infect humans. They can be difficult to remove from the home and can survive for more than 100 days without a host. Bites from fleas can trigger allergic reactions, but they will not often have a serious impact on a person's health.

Are fleas harmful to humans?
Flea bites in and of themselves are not dangerous. It is what lies on their mouthparts and in their saliva that threatens health. To be more specific, fleas can carry bacteria, pathogens, and other sickness-causing organisms. These organisms are transferred to people and animals that fleas bite.
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.
A flea might live a year and a half under ideal conditions. These include the right temperature, food supply, and humidity. 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.
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.
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.
Either finely ground refined household salt or sea salt can be used to kill fleas in your home. Simply sprinkle the salt evenly over carpeted areas or furniture and leave it be for about 12-48 hours. Since flea eggs can fall in between carpet fibers, it's best to brush the salt in for better results.
A very effective, natural insect killer is diatomaceous earth, killing fleas within four hours. It is non-toxic to pets and humans, but it's fine dust, and like any particulate matter, it should not be inhaled.
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.
Flea bites may appear in a straight line or a cluster of many bites. Flea bites most commonly occur on your legs, especially your feet, calves and ankles. Flea bites rarely appear above your knee, unless you spend a lot of time sitting or lying down.
Fleas like hiding in crevices. Their populations are more numerous in places where they can feed (like pet bedding and living rooms) and reproduce undisturbed (like lower-traffic areas or in carpeting). They also inhabit upholstery, furniture, and other common household furnishings, especially where they can stay warm.
While fleas have an impressive sense of smell, one of the only smells they are attracted to is carbon dioxide. Many scents can repel fleas, including mint, rosemary, lavender, eucalyptus, and citronella. You may consider adding some pet-friendly plants that repel pests to your garden to help keep fleas at bay.
Phototaxis is a term describing response to light. Cat fleas are positively phototactic, meaning they're attracted towards sources of light. In one experiment, adult fleas were placed in a dark area. Within 40 minutes, 93% of them moved to a lighted area.
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.
At What Temperature and How Quickly Do Fleas Die? Adult fleas die at temperatures colder than 46.4°F (8°C) and hotter than 95°F (35°C). Immature fleas, which refers to both flea eggs and larvae, are slightly more susceptible to the cold, dying at temperatures below 55.4°F (13°C).
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.
Adult fleas feed on the blood of their host animals (cat, dog, human, rat, mouse, squirrel, etc.). Larvae feed on the dried blood that is expelled in the feces of adult fleas and occasionally on molts from other 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.
You can use a homemade spray to kill fleas on a mattress. To make the spray, combine equal parts water and distilled white vinegar. Spray the mixture on the fleas and all over the mattress. Follow this up with a generous sprinkle of salt all over the mattress, and let it sit overnight.
If the flea infestation is light, frequent and thorough vacuuming may eventually eliminate the problem. Moderate to heavy infestations, however, will usually necessitate the application of a residual insecticide to carpets, baseboards, cracks and crevices, and other areas where fleas may be present."
