There are several different types of fleas that can be found in this area, all similar in behavior and appearance. Adult fleas are parasites that feed off the blood of a host such as a pet or person, giving them the ability to spread disease. In their immature larval stage, fleas feed on dried blood they get from adult fleas or pets. They are around 1/8" long, dark colored, and flat. Being flattened side-to-side makes them difficult to squash, and allows them freedom to move through hair. With an ability to jump 6" high, they have no problem getting on and off their host quickly. Fleas can be difficult to control because of their large numbers, small size, even smaller eggs, and their ability to go a long time without feeding.
