How do fleas breed?

Do fleas have sex?  Do they do it “flea style”? Interestingly enough the answer varies depending on species and environmental conditions.  The “water flea”, for example, reproduces asexually under normal conditions, producing more and more females.  When conditions change due to overcrowding and limits on food supply, they begin to asexually produce males.  The males then “have sex” with the females.  The result are eggs encased with a protective coating designed to withstand the enviromental changes.    Full “university professor style” article here.    The video below explains the flea life cycle and their crazy states of existence. Note: Please disregard the ironic ads you might see for toxic flea control products in these videos as we have no control over which ads display.  The toxic pesticide industry is well funded and they advertise everywhere including prime time television.  Please join us to educate and spread the word about safer alternatives.
