Where Does Fleas Come From?

Fleas are tiny blood suckers, and they can make pets miserable. Some species have been known to cause diseases, including bubonic plague. This illness is transmitted to humans by rodents that are bitten by infected fleas. Major plague outbreaks have occurred in human history, including the Plague of Justinian, which killed up to 540 people, and the Black Death, which killed about one million people.

Fleas usually reside outdoors in tall grass, but they can also be found inside a home. Fleas are attracted to body heat, carbon dioxide, and vibrations. Fleas can enter your home even if you do not have pets. It is important to keep your home clean and dry.

Fleas can migrate from one area to another, and are often carried by outdoor wildlife. Some of these hosts include feral dogs, raccoons, coyotes, skunks, and opossums. Flea eggs are shed by these wildlife and the adult fleas then jump on nearby animals. Fleas can go months without a blood meal, but they must eat before they lay eggs.

Fleas can also be spread through the air or through pet bedding. Fleas can cause damage to carpets, upholstery, curtains, and furniture. Infections and fleas can cause health problems. The best way to protect your pet from fleas is to prevent them from entering your home in the first place.
