ARBICO Organics line of Steinernema carpocapsae Beneficial Nematodes PRO are OMRI Listed for use in organic production. They are delivered in a non-synthetic wettable powder. The OMRI listed beneficial nematodes can be used by both residential and commercial users.
Beneficial Nematodes are live microscopic organisms (non-segmented round worms) that occur naturally in soil throughout the world. The beneficial nematodes we sell are parasitic to insect pests that typically have a developing (larval or pupal) stage of life in the soil. They have been known to parasitize above ground stages of adults, nymphs and larvae. They will not harm mammals, aquatic life, birds, reptiles or amphibians. After being applied to the soil, the nematodes locate pests and enter through various body openings or directly through the body wall. Once inside, the nematodes produce bacteria that is injected into the pest's blood.
Beneficial Nematodes release the bacteria in order to create food and a hospitable environment for their own reproduction. As the food resources within the dead pest become scarce, the nematodes exit and immediately begin searching for a new host. As long as there is a suitable host, they will continue to survive and parasitize.
