Nematodes

The next predators of fleas that eat fleas that we want to introduce to you are the nematode. It is a microscopic and multicellular insect with a smooth and unfragmented body. The genus Nematoda includes hundreds of species with a wide variety of habitats. Common habitats for nematodes include plant parts, soil, and the bodies of other animals such as insects.

Two species of nematodes can be used to control fleas. The first species is steinernema carpocapsae. Called SC, these worms are very effective when dealing with fleas or adapted larvae on highly mobile surfaces. The second nematode used for flea control is steinernema feltiae. These organisms reside mostly in the soil. They are also effective against soil fleas.

Steinernema feltiae feed on fleas mainly in their larval and pupal stages. They parasitize fleas in their larval and adult stages on the ground. In the process, they do almost no harm to aquatic species or any other animals that reside in the soil. Both SC and SF use the same technique to kill fleas. They usually enter the flea's system through pores and body openings such as the mouth and anus.

Once they're inside, they release a certain type of bacteria that kills the pet. However, these bacteria have almost no effect on them. After their host dies, they grow and reproduce rapidly to give birth to other young.
