A flea can jump 60 times its length in height and 110 times its length in distance, equivalent to a 1.8 m (6 ft) adult human jumping 110 m (361 ft) vertically and 200 m (656 ft) horizontally. Rarely do fleas jump from dog to dog. Most flea infestations come from newly developed fleas from the pet's environment. [6]

Potatoes are the most significantly affected host, but if not available, the flea beetle will damage aubergine ( Solanum melongena ), Chinese lantern, ground cherry ...
