The Life of Fleas

Fleas have four main stages in their life cycle: egg, larva, pupa, and adult. The total life cycle of fleas can range from a couple weeks to several months, depending on environmental conditions. With this being said one must know how fleas evolve in order to have a proper defense.

The Fleas Egg

It all starts from a single egg. Eggs usually fall off of the animal into the carpet, bedding, floorboards, and soil. From here it can take anywhere from a few days to a few weeks for the egg to reach maturity and hatch. Once mature, the larva uses a chitin tooth, a hard spine on top of the head that disappears as fleas mature, appears into the world.

The Flea Larvae Stage

The Life of Fleas The larval stage actually has three developmental stages within this one stage. Larvae are only about 1/4" long and semi-transparent white with small hairs along their body and actively move. They consume the feces of adult fleas and other organic debris found in the carpet, bedding, and soil. Depending on the amount of food present and the environmental conditions, the larval stage lasts about 5 to 18 days. Ending the larval stage the larva spins a silken cocoon and pupates.

Flea Pupa Stage

The pupa is the last stage before adult. The adult fleas can emerge from the cocoon as early as 3 to 5 days, or it can stay in the cocoon for a year or more, waiting for the right time to emerge. When is the right time? Stimulants such as warm ambient temperatures, high humidity, even the vibrations and carbon dioxide emitted from a passing animal will cause the fleas to emerge from the cocoon faster. Once the fleas break through the cocoon they have became an adult flea.

Adult Fleas

Adult fleas are very flat side to side. They posses hair-like bristles on the fleas body and legs to aid in their navigation through pet hair. Fleas have 3 pairs of legs, the hindmost pair designed for jumping. Fleas are well known for their jumping abilities. Adult fleas prefer to live on the animal and their diet consists of blood meals courtesy of the host animal. The female fleas lay white, roundish eggs. Adult female fleas can lay up to 50 eggs per day, 500-600 eggs over several months.

The entire life cycle is quite variable, as evidenced by the variability in each life stage progression. As mentioned above, the cycle can be as short as two weeks or as long as two years. That is why it is so important to use Fleadome Act for your all natural flea control and flea prevention.
