The beneficial nematode Heterohabditis bacteriophora (Larvanem) is a natural enemy of white grubs (larvae of European Chafer, Japanese Beetle, and June Beetles), cutworms, and larvae of root borers, root weevils, flea beetles, as well as other pests commonly found in lawns and turf.

Predatory nematodes are most effective when used as part of an Integrated Pest Management program and when the pest you are treating is in its larvae stage. The soil must be moist and soil temperature ideally between 13° to 33°C (55° to 91°F) for them to be effective. Keep nematodes away from direct sunlight as they are sensitive to UV light. They are best applied in the evening, preferably during a rainy spell.

The fifty (50) million nematodes in the package will cover an area of 230m2 (2,500 square feet).
