Species of entomopathogenic nematodes, or round worms, have been shown to be beneficial for controlling many types of greenhouse pests, including fungus gnats, shore flies, and some control of western flower thrips. In the nursery, nematodes can provide some control of root weevils, wireworms, cutworms, and spotty control of Japanese beetle grubs. In the same manner that these nematodes invade their soil-borne hosts, nematodes can be bred in Galleria mellonella wax worms. Rearing them yourself can save you money and prevent repeat ordering with your supplier.
