Five interesting facts about fleas

August 8, 2018

No shortage of species

Scientists estimate there are more than 2,500 species of fleas on the planet. Within the lower 48 U.S. states, flea species number 325.

They lay a lot of eggs

Fleas lay eggs on other animals, and a single adult flea can lay 50 eggs per day and 2,000 throughout its very short lifespan.

A troubled past

During the Middle Ages, tens of millions of people died of the plague, or Black Death, as it spread across Asia and Europe. Fleas carried the plague bacteria and transmitted it to humans.

Humidity preferred

Fleas don’t thrive in low humidity, which is why they aren’t as much of a pest problem in arid areas such as the Southwest.

A love for leaping

Cat fleas, the most common flea pest, can propel themselves a full 12 inches forward or upward. That’s a jumping distance equal to about 150 times its own height.
