Fleas leave a lot of evidence when they have taken up residence on your pet. They actually leave behind a pepper like substance which is actually called “flea dirt.” It can be spotted on your pet’s skin and even around your house. The flea dirt can be found in your bed, carpet, and your sofa. These specks are actually dried blood.
You will also find flea eggs on your pet that can also fall off all over your house. Fleas lay eggs on your pet that look like tiny white ovals. In only a few days, the flea eggs turn into flea larvae. Flea larvae are little, worm-like things with brown heads that feed on the flea dirt until they wrap themselves up into a cocoon called a pupa. At four weeks, that little white egg will develop into fully grown biting fleas.
