The Flea life cycle is similar to the butterfly life cycle. Female Fleas lay eggs that turn in to grub-like larvae. The larvae then develop into pupae and settle inside a cocoon. They wait for a host to start their life and suck blood. When something warm moves by the pupae, they unzip the cocoon and jump on the animal or human body. All this happens in three seconds and the flea can jump as high as four feet.
Fleas feed on blood, and a flea can live without a blood meal for 100 days. A female has to have a blood meal to lay eggs. In addition, it lays eggs within 36-48 hours of having the first blood meal. A female flea can lay 2,000 eggs in her lifetime.
Fleas are very tiny creatures, the adults average 1/8th of an inch in size. They have a flat body from side to side, with piercing mouths that help them in sucking blood. Fleas are often confused with bed bugs, lice and ticks. However, fleas are reddish brown to black in appearance, and they are also wingless. adult fleas go through stages including adults, pupae, larvae and eggs. Fleas in all stages should be killed to rid your house of them completely. Resistive pupae and larvae grow on to become adult fleas in a few weeks even though the adult fleas are killed. Fleas should be removed from all stages in their life cycle, to protect your family and pets.
