White fleas can't jump.....

Fleas carried the Bubonic Plage organism or "Black Death" which killed millions in Europe in the 14th century, including 1/2 the population of Italy. Rats brought them from marshes in an area in China westward to the Black Sea, where they boarded trade ships bound for Italy. They then migrated West to England, and turned eastward to Russia. It was found very sanitary conditions (a new idea at the time) was the only thing effective to halt it's progress. That, and fire.
