Beneficial nematodes seek out and kill all stages of harmful soil-dwelling insects.
They can be used to control a broad range of soil-inhabiting insects and above-ground insects in their soil-inhabiting stage of life. More than 200 species of insect pests from 100 insect families are susceptible to these insect predators. Nematodes only attack soil dwelling insects and leave plants and earthworms alone.
Beneficial garden ladybugs for controlling pests in your garden are the most popular and widely used beneficial insects for commercial and home use. Ladybugs are capable of consuming up to 50 to 60 aphids per day but will also eat a variety of other insects and larvae including scales, mealy bugs, leaf hoppers, mites, and various types of soft-bodied insects.
