Fleas are perfectly designed by nature to feast on anything containing blood. Like a shark in the water or a wolf in the woods, fleas are ideally equipped to do what they do, making them very difficult to defeat. The bodies of these tiny parasites are extremely hardy and well-suited for their job.
A flea has a very hard exoskeleton, which means the body is covered by a tough, tile-like platecalled a sclerite. Because of these plates, fleas are almost impossible to squish. The exoskeletons of fleas are also waterproof and shock resistant, and therefore fleas are highly resistant to the sprays and chemicals used to kill them.
Little spines are attached to this plate. The spines lie flat against the flea’s thin, narrow body as the flea scurries through an animal’s fur in search of food.However, if anything (like fingers or a self-grooming pet) tries to pull a flea off through the hair coat, these spines will extend and stick to the fur like Velcro.
Fleas are some of the best jumpers in the natural world. A flea can jump seven inches, or 150 times its own length, either vertically or horizontally. An equivalent jump for a person would be 555 feet, the height of the WashingtonMonument. Fleas can jump 30,000 times in a row without stopping, and they are able to accelerate through the air at an incredibly high rate—a rate which is over ten times what humans can withstand in an airplane.
Fleas have very long rear legs with huge thigh muscles and multiple joints. When they get ready to jump, they fold their long legs up and crouch like a runner on a starting block.Several of their joints contain a protein called resilin, which helps catapult fleas into the air as they jump, similar to the way a rubber band provides momentum to a slingshot. Outward facing claws on the bottom of their legs grip anything they touch when they land.
The adult female flea mates after her first blood meal and begins producing eggs in just 1 to 2 days. One flea can lay up to 50 eggsin one day and over 2,000 in her lifetime. Flea eggs can be seen with the naked eye, but they are about the size of a grain of salt. Shortly after being laid, the eggs begin to transform into cocoons. In the cocoon state, fleas are fully developed adults, and will hatch immediately if conditions are favorable. Fleas can detect warmth, movement, and carbon dioxide in exhaled breath, and these threefactors stimulate them to emerge as new adults. If the flea does not detect appropriate conditions, it can remain dormant in the cocoon state for extended periods. Under ideal conditions, the entire life cycle may only take 3 weeks, so in no time at all, pets and homes can become infested.
Because of these characteristics, fleas are intimidating opponents. The best way to control fleas,therefore, is to take steps to prevent an infestation from ever occurring.

 Pulgas son perfectamente diseñadas por naturaleza para fiesta en cualquier cosa que contenga sangre. Como un tiburón en el agua o un lobo en el bosque, las pulgas son idealmente preparadas para hacer lo que hacen, que les hace muy difícil de derrotar. Los cuerpos de estos pequeños parásitos son extremadamente resistentes yapropiados para su trabajo.
Una pulga tiene un exoesqueleto muy duro, lo que significa que el cuerpo está cubierto por una placa resistente, azulejo-como llama un esclerito. Debido a estas planchas, las pulgas son casi imposibles de squish. Exoesqueletos de pulgas también son impermeables y a prueba de golpes, y por lo tanto son altamente resistentes a los aerosoles y productos químicos utilizadospara matar pulgas.
Espinas poco se unen a este plato. Las espinas Acuéstese contra cuerpo delgado, estrecho de la pulga, la pulga scurries a través de la piel de un animal en busca de alimento. Sin embargo, si nada (como los dedos o una mascota self-grooming) intenta sacar una pulga a través de la capa de pelo, estas espinas ampliará y se pegan a la piel como el Velcro.
