They don't have wings but do have amazing jumping capabilities, there are 2000 plus species and sub-species of known flea worldwide. Fleas lay small oval-shaped eggs that are white in colour when they hatch the larvae are tiny with pale worm-like bodies. Which will then feed on all types of organic matter but prefer the feces of adult fleas. The female flea typically lays in batches of about 20 eggs and can lay up to 5000 eggs in its life-cycle. Fleas will infest almost any type of warm-blooded animal, including humans and our homes as well.Credit: wiki commons
