But new research may have settled one major question: How do fleas lift themselves off the ground? One mystery solved, another remains Fleas jump more quickly and with more force, than would be possible using muscle. This mystery was solved in , when researcher Henry Bennet-Clark discovered that the fleas, using an elastic pad made of a protein called resilin and, like a tensed spring, release the pad to catapult themselves into the air.
But this discovery gave rise to another debate that remained unresolved: How did the fleas transfer the force from the spring mechanism to the ground to lift off? Bennet-Clark believed a flea pushed down through its tibia and tarsus equivalent to a human shin and foot or toe, respectively. Meanwhile, fellow flea researcher Miriam Rothschild believed that fleas pushed off using their trochantera equivalent to human knees.
Sutton and study collaborator Malcolm Burrows, also of the University of Cambridge, resolved the debate using high-speed cameras, an electron microscope and computer modeling, plus 10 hedgehog fleas donated by the Tiggywinkles Wildlife Hospital Trust. The evidence Before fleas take off on a jump, their knees appear to rest on the ground, creating an important sticking point in the debate.
With the aid of the cameras, the researchers filmed the fleas jumping 51 times. Because fleas are such great jumpers, many people think fleas are capable of flight. To say this is an impressive feat of athleticism would be an understatement.
For example, if a person with a height of 6 ft. Without wings to help propel them, you may be wondering how fleas are even able to jump so high. In other words, fleas put in a lot of legwork to get to where they want to go.
Like other insects, a flea has three pairs of legs, with the back pair being longer than the other two. Resilin is like an elastic pad of stretchy protein, which extends and contracts when the flea jumps and lands. As a result, fleas can catapult themselves off a surface quickly and with a lot of control. More often than not though, a flea is going to look for a furry animal to feed on.
Because of these reasons, our furry friends are prime targets for fleas. For your home, you have options like an indoor fogger , carpet spray , or home spray.

By taking the proper precautions, you can be a true hero in the eyes of your pet. Traub, Robert, Miriam Rothschild. Centers for Disease Control and Prevention. Donovan, John. Read More. Article Do Fleas Jump? Up, Up, and Away Interestingly, a flea can jump approximately eight inches by catapulting itself forward. A flea's life-cycle consists of four stages: Egg.
Eggs are small and smooth and tend to fall off your pet, ending up outdoors or inside your home. Larvae live on your pet's skin—specifically around any dried blood.
Larvae can take anywhere from four to 18 days before entering the pupae stage. Pupae are fleas in a cocoon state. Pupae live from eight to nine days but can remain in a cocoon for more than six months.
Adult fleas can live more than days in perfect conditions. In that time, they lay eggs and may transmit illness and disease. Fleas Multiply at an Alarming Rate A flea's reproductive abilities are pretty incredible.
