That works out to about 2000 potential eggs in the course of the span of a flea’s potential lifespan of 60-100 days. A lot of these eggs will develop into fleas that may reproduce and it’s simple to see how infestations can occur so shortly.
As soon as an grownup flea hatches, the one objective it has is to feed. It has to feed inside every week or it might die, though some can survive for much longer in the precise situations and surroundings. As soon as the flea feeds and will get a stomach stuffed with blood, they transfer on to mating with one other flea to perpetuate the life cycle.
Although it doesn’t normally occur throughout the first 24-36 hours, as soon as a flea feeds and breeds, it’ll begin laying eggs.

Pupae are a whitish colour and really sticky to assist them camouflage themselves with particles from their surroundings. Although pupae are more durable than larvae, they’ll nonetheless die throughout this stage if the humidity is low or if they’re uncovered to pesticides.
The pupae course of can take 5 days as much as two weeks to totally develop. Nonetheless, as soon as the cocoon is spun and two weeks have handed, they’ll sit and hibernate in that stage for a number of days as much as six months with no meals. That is how they survive situations that will not be ultimate, akin to excessive temperatures.
Primarily, it is a pre-adult state the place the flea simply waits for the precise time to emerge fully-formed. So, regardless of what number of grownup fleas and larvae you handle to eradicate, there are at all times extra, prepared and ready to start the entire course of as soon as once more. It’s a nasty cycle that may be troublesome to interrupt and defeat. When a flea is able to emerge from it’s cocoon, it is going to achieve this due to some type of stress they’ve detected.
This is likely to be stress from warmth or is likely to be stress from the host animal if it lays down on the cocoon. They simply want the precise set off to emerge and start to repopulate, even when all grownup fleas and larvae have already died, which typically occurs in properties the place there was a flea infestation, however no host to feed on for some time.
