How Can a Human Die From Fleas?

Fleas are parasitic insects that feed on the blood of living creatures. Most species live on animals and prefer them as hosts, but humans can also get fleas from pets. In developed countries, fleas do not commonly infest humans. They are more commonly associated with wildlife, like cats and dogs. However, fleas on humans can be a problem in farms and houses with a large number of animals.

Adult fleas have mouthparts that are designed to puncture an animal’s skin and drink its blood. While fleas prefer to feed on the blood of a pet, they will also attack humans. But, when the preferred host is gone, the flea population will start to increase. And once this happens, fleas will attack any warm-blooded animal, even humans!

Thankfully, fatal fleas are not a common problem. Although fatal fleas are rare, they can cause serious illnesses in humans and animals. Therefore, if you notice fleas in your home, don’t hesitate to take action. There are several steps you can take to prevent fleas from infesting your home.

Fleas are not only parasitic, but they are also vectors of disease. Many fleas carry the parasite Yersinia pestis. This bacterium lives on more than 200 rodent and lagomorph species worldwide, with rats being the most common reservoirs.
