The Life Cycle of a Flea

The lifetime of a flea progresses by means of 4 levels:

A lot of these eggs will develop into fleas that may reproduce and it’s simple to see how infestations can occur so rapidly.

As soon as an grownup flea hatches, the one objective it has is to feed. It has to feed inside every week or it could die, though some can survive for much longer in the fitting circumstances and setting. 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 inside the first 24-36 hours, as soon as a flea feeds and breeds, it’ll begin laying eggs. This normally occurs inside the first week except they’re unable to feed. As soon as the feminine flea begins laying her eggs, she’ll begin laying roughly 20-30 eggs per day for about 3-9 days.

As soon as larvae undergo their molting processes, the larvae spin cocoons to enter the pupae stage. Pupae are a whitish colour and really sticky to assist them camouflage themselves with particles from their setting. Although pupae are harder than larvae, they will 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 completely develop. Nonetheless, as soon as the cocoon is spun and two weeks have handed, they will sit and hibernate in that stage for a number of days as much as six months with no meals. That is how they survive circumstances that might not be splendid, equivalent to excessive temperatures.

Basically, it is a pre-adult state the place the flea simply waits for the fitting 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 tough to interrupt and defeat. When a flea is able to emerge from it’s cocoon, it can achieve this due to some type of stress they’ve detected.
