If you think just killing the adult fleas on your pet means he or she is protected from further flea infestation, think again!

Flea eggs, pupae, and larvae could still be lurking on your pet, just waiting to reach adulthood and start your furry friend scratching all over again.

Before a flea reaches adulthood, they've gone through three previous life stages: egg, larva, and pupa. Depending on environmental conditions, it can take between two weeks and six months for flea eggs to reach adulthood, although the average is three to four weeks in most homes. While you may think the fleas are dead today, in as little as two weeks, your pet could be re-infested with hungry adult fleas.
