Product Information - What are BENEFICIAL NEMATODES?
FROM OUR SUPPLIER:
Beneficial Nematodes are microscopic organisms (non-segmented roundworms) that occur naturally in soil throughout the world. The species we utilize (H. bacteriophora, S. feltiae) are parasitic to insects that have a developing (larval or pupal) stage of life in the soil. Beneficial Nematodes have also been observed to parasitize above-ground stages of adults, nymphs and larvae. Beneficial Nematodes will not harm mammals, aquatic life, birds, reptiles or amphibians.
After application, Beneficial Nematodes locate pests and enter them through various body openings or directly through the body wall. Once inside, the nematodes inject bacteria that kill the pest insect within 24 to 48 hours of first contact. Maximum control occurs over a period of two to four weeks. As the 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.
Beneficial Nematodes are recommended for application whenever larvae or grubs are present, generally during the Spring and Autumn months. Be on the lookout for signs of adult insects. If adults are present, their eggs may inevitably soon hatch. A singular Nematode application may not be enough to eradicate a pest population that has become established over a period of years.
Cold weather will guarantee a significant decline in the Nematode population. Like their insect prey, Beneficial Nematodes will become dormant during the Winter. Any survivors would be too few in number to ensure adequate suppression of pest populations. If the pest insect reappears the following Spring, another Nematode application is necessary.
