Beneficial Nematodes are live microscopic organisms (non-segmented round worms) that occur naturally in soil throughout the world. They are parasitic to insect pests that typically have a developing (larval or pupal) stage of life in the soil; however, they have been known to also parasitize above ground stages of adults, nymphs and larvae.   They are completely safe to use and will not affect mammals, aquatic life, birds, reptiles or amphibians.After application, the nematodes immediately get to work. Upon finding a pest, they enter it through various body openings or directly through the body wall. Once inside, it is not the nematode that actually kills the pest, but the toxic bacteria inside the nematode's gut that is the real weapon – symbiotic bacteria, that when released inside and insect, kill it within 24 - 48 hours by causing blood poisoning.

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.
