The flea is a blood-sucking insect that can carry and spread disease very quickly and can become a severe pest in your home. To eliminate this pest, we need to understand the flea's entire life cycle to get rid of them once and for all.

The Flea Egg Stage

Fleas are notorious for laying eggs just after a blood-feeding session with your pet or yourself. These fleas can lay around 50 eggs a day! This only accounts for one flea. As you can see, this is why fleas multiply so fast and quickly become a pest in your home. Also, flea eggs can fall off your pet’s fur as they move around your house; your pet is just spreading out the eggs all over the place.

Also, note that more than half the population consists of flea eggs at this stage, and they can take anywhere from two days and as late as weeks to hatch.

The Flea Larva Stage

Flea Population accounts for about 35% in this stage. It is also the most vulnerable stage in the flea’s life cycle, as it needs humidity to survive.

After the egg hatches, the Larvae comes out. It looks like a tiny worm with a transparent white-ish body. That will right away seek shelters like floor cracks, carpet, furniture, or any dark locations where it will be safe to continue to grow.

While in this stage, the larvae eat organic debris from the environment, like hair, dead skin, even other flea feces. They will go through three phases of skin shredding, and when fully grown, it spins a water-tight silky cocoon, almost invisible due to blending into its surroundings and reaching the toughest phase of its life cycle.

The Flea Pupae (cocoon) Stage

The pupae stage is proven to be the toughest stage of the flea life cycle. The cocoon has a sticky outer layer that helps them to hide deeply in carpets. It is also not easily removed by sweeping or lightly vacuuming. This cocoon is so strong that it protects the flea from chemicals.

While in the pupae stage, it goes through three more stages of development. It can take from 7 to 10 days to complete.

After it has fully developed inside the cocoon, the fully grown adult flea will not necessarily emerge right away. If the environmental conditions are not right, it will remain dormant for weeks or months before it arises.

When the environment becomes ideal or senses the presence of a potential host, the adult flea emerges.

The Adult Flea Stage

Surprisingly, adult fleas make up about 5% of the population in an infested home. They are very tiny, they have six legs like most insects, and their hind legs are long and powerful, making it very easy for them to jump into their host.

Fleas will bite up to 400 times per day, and it only takes one Flea 21 days to multiply into more than 1000 fleas! Once the Adult Flea emerges from its cocoon, they instantly look to feed, either from your pet or yourself.

Fleas can live more than 100 days throughout their life cycle, making them very tough and annoying pests to have at home. So if you start noticing fleas in your home, take action right away, do not wait until it is too late!
