This is a flea that mostly feeds on the blood of dogs. It can easily spread the cucumber tape worm and can also bite humans. The female needs to have blood to enable it to produce eggs. It can lay as much as 4000 eggs on the fur of the host which goes through four stages in a life cycle.
This cycle takes as much as three weeks and can take even less time if temperatures are conducive as cold conditions slow down the cycle. During this cycle five percent of the time they are on the host and the remaining time in surrounding areas of its habitat.
The flea has mouth parts that are right for piercing and sucking blood as they need to suck blood from their hosts to live. They are wingless, and their bodies are flattened on each side. They are covered with hair and spines which helps them, easily hide in the hosts hair and travel unnoticed on it. They also have long hind legs that they use for jumping.
Apart from spreading worms to hosts, fleas can spread skin problems and infections as well as health issues such as anemia. In animals, their presence is indicated by the animal constantly scratching and biting themselves especially around the neck, tail and head area. They also cause itching discomfort to a host. In humans, they are normally located in arm pits and other hidden areas such as folds of skin in the knees and elbows.
