Norman Reedus guides a tour of his 'Walking Dead' trailer. [ SPOILER ALERT: Read on only if you have already watched Sundayâs âRememberâ episode of The Walking Dead .]. The walled-off community of Alexandria could prove to be a place where the characters of The Walking Dead settle down for a long time. But the woman who plays the leader of Alexandria simply canât sit still.
Fleas go through four life cycle stages of egg, larva, pupa, and imago (adult). Adult fleas must feed on blood before they can become capable of reproduction. Flea populations are distributed with about 50% eggs, 35% larvae, 10% pupae, and 5% adults.
Mathematically, this means that the average flea lifespan is five times longer (if a flea has to touch diatomaceous earth 5 times to die, then that would be 5 hops with full coverage and 25 hops on average with 20% coverage).
