Fleas Life Cycle

Understanding a fleas life cycle is fundamental in controlling and eliminating the problem of a flea infestation. As fleas can cause itching, swelling and discomfort for up to two weeks, making certain that you get rid of the pests permanently is very important. As flea bites can also transmit diseases, it is in the interest of your health that you work to stop fleas from living in the same space that you do.

The first stage of a fleas life cycle is the egg. The female flea lays eggs on the host, usually a mammal. Cats, dogs and humans all make good hosts for fleas, as fleas enjoy body warmth. Unlike some pests, the eggs of a flea are not sticky, so the eggs tend to fall off and develop in the carpet. As a flea can lay up to fifty or more eggs in a day, one female flea is enough to start a massive infestation.

The next stage of a fleas life cycle is the larva stage. Larvae are when the egg has developed into a partly developed flea. This flea cannot yet live outside of the egg, and does not look very much like a flea.

After the larvae stage, the next stage in a fleas life cycle is the pupa stage. This is when the flea is almost ready to leave the egg and become a full-fledged flea. While flea eggs can develop into larvae quickly, a flea may remain in the pupa stage for up to two years. This is the stage where many people have problems killing the infestation. As the lifespan of the pupa is so long, you must be on constant guard against a resurgence of fleas.

Once the pupa hatches from the egg, the fleas life cycle begins anew.

While understanding a fleas life cycle can be beneficial in preventing fleas from returning, you will have to take steps to stop the infestation long after fleas have stopped biting you and your pet. While chemicals like flea foggers and Borax can greatly reduce the number of viable eggs, only several years will prevent the pupa from being able to survive.

If you have had problems with fleas, using pet medications can help keep the numbers at a minimum. Combining these regimes with flea traps and other treatments can help ensure that the flea infestation will never reoccur.

If you are suffering from a severe infestation, you may want to contact a pest control agency and seek professional advice.
