4 Life Stages Of Fleas: Eggs, Larvae, Pupa, Adult fleas

If you know dogs, you probably know what fleas are, and you certainly don’t want to see fleas at home, on yourself, or on dogs. However, these parasites are more than simply annoying things. Fleas pose a major threat to the health of dogs and other animals including humans. These tiny external parasites feed on animal blood, and their bites can cause many health problems. As a dog owner, you should know some basic knowledge about the risks, prevention and treatment of fleas. With this correct knowledge, you can better keep your dog and your home away from fleas.

Basic knowledge about fleas

Fleas are small insects without wings. Their bodies are hard and flat, and they can easily pass through pet hair. A flea’s legs can jump long distances, and its mouthparts can suck blood. This parasite feeds on the blood of the host (usually a mammal). There are several types of fleas, but the most common fleas in North America that live on dogs, cats, and other pets are cat fleas, also known as ctenophores. Although these fleas can bite people, humans are not their ideal hosts. This fleas like cats, dogs, rabbits, rodents and other similar small mammals.

The life cycle of a flea

The life cycle of a flea has four stages.

Eggs: An adult female flea can lay 40 eggs a day (20-30 eggs are also very common). These eggs are laid on the host, but will soon fall from the host to the surrounding environment and fall on the pet In bedding, carpets, wooden floors and other interior decorations, at home, these eggs usually hatch within 2 to 3 days.

Larvae: Larvae come out after the eggs hatch. These tiny creatures mainly feed on flea feces (basically dried blood) and unhatched eggs in the environment. The larva undergoes three growth stages before it cocoons and enters the pupal stage. In most household conditions, the larval stage usually lasts 5 to 15 days.

Pupa: Inside the cocoon, the pupae begin to transform into fleas. Cocoons are almost indestructible and can absorb dust and debris to camouflage themselves and protect themselves. The pupae can sleep for several months in a normal environment. Fleas in the pupal stage usually do not emerge from their cocoons until they sense the host; they can do this by sensing temperature and pressure, etc.

Adult fleas: Fleas that have just broken out of the cocoon jump onto the host and begin to suck blood as soon as possible. Female fleas usually lay eggs within two days after the first blood-sucking. It takes blood from the host, and then discharges the blood and eggs into the host to start a new life cycle. Adult fleas usually live on pets for one to two weeks, but they can live longer under ideal artificial conditions.

Summary

After understanding the life cycle of a flea, you should be able to understand why a dog will be infected with a flea a few months after moving to a new home or to a new place without pets. As soon as the pupa senses the presence of the host, it will burst out. Hundreds of fleas may suddenly appear on a dog’s body, and you can’t even think of where they came from! In just a few days, fleas reproduced wildly, and the infection seemed to be out of control.
