Heterorhabditis bacteriophora harmless to the ornamental crops, humans, the environment and other beneficial insects, these nematodes actively seek out grubs, Japanese beetles and vine weevil larvae by swimming in the thin film of water on soil particles. They locate hosts by detecting carbon dioxide and other waste products. After locating pest larvae, nematodes invade through natural body openings and inject bacteria into the insect. Bacteria develop within the insect and it dies of septicemia. These nematodes boast a deep-moving active-hunting, “cruising” characteristic which make them superior to many other species for the purpose of grub control.
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.
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.Finally, there is no evidence that parasitic nematodes or their symbiotic bacteria can develop in vertebrates. This makes nematode use for insect pest control safe and environmentally friendly. The United States Environmental Protection Agency (EPA) has ruled that nematodes are exempt from registration because they occur naturally and require no genetic modification by man.
Beneficial nematodes can be applied anytime during the year when soil-dwelling insects are present and soil tempertures are above 52-F during the day. Beneficial nematodes seek out and kill over 200 pest insects in the soil. They are a natural effective alternative to chemical pesticides.
