Did you know…?

  • It jumps more than a hundred times its own length thanks to a block of resilin, an elastic protein that stores energy like a spring and releases it all at once.

    From Cat Flea

  • Only a tiny fraction of the population is on the animal: the eggs, larvae and pupae build up in carpets, beds and cracks in the floor, which is why treating the pet alone never clears an infestation.

    From Cat Flea

  • It transmits the tapeworm Dipylidium caninum and the bacterium that causes cat scratch disease.

    From Cat Flea

  • Its role in the great plague epidemics has been debated for decades: the models that best reproduce the speed at which the Black Death spread across Europe implicate human fleas and lice, and not the rat flea alone.

    From Human Flea

  • It was the star of the flea circuses of the nineteenth century, harnessed to tiny carts and wheels to exploit its extraordinary strength.

    From Human Flea

  • Its decline in western Europe is down to the spread of hard flooring, the vacuum cleaner and frequent washing of bedding.
