Question: How do nematodes work?

Answer: Beneficial nematodes seek out and kill the immature stages of harmful soil-dwelling insects before they become adults. 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.

They are a natural and effective alternative to chemical pesticides, and have no detrimental affect on non-target species such as ladybugs, earth worms and other helpful garden insects. Beneficial nematodes can be applied anytime during the year when soil-dwelling insects are present and daytime soil temperatures are above 48-F.
