Can Fleas Go on Humans?

Fleas are not only dangerous to animals but can also be dangerous to humans. Their bites can cause pain, swelling and bleeding under the skin. They can also cause infections and other serious ailments. Fleas can also carry bacteria, so it is crucial to take care of these insects right away.

Human fleas can transmit Yersinia Pestis, a bacterium that causes a disease called plague. This disease was responsible for millions of deaths in the Middle Ages. It is still possible to contract this disease today. While it is rare in the United States, it can still cause severe illness and even death.

Fleas can also lay eggs on humans. Luckily, if you kill them, you can prevent them from reproducing. Flea eggs are whitish or ovular, and fertilized female fleas lay up to 800 eggs throughout their lifetime. In a normal environment, fleas lay two to four eggs a day, but in conditions that are unfavorable, they can lay as many as thirty eggs.

Adult fleas are small and flat insects, measuring between one and six millimeters long. They have six legs and can burrow through hair and skin to feed. Fleas are attracted to warm-blooded mammals with fur. Therefore, when fleas live on your pet, they can easily spread to your home. Often, fleas can enter your home by grabbing onto your pet while playing outside. Their fur and feathers can also carry them in the house.
