How it works
The Hb type of nematodes patrol the soil to a depth of 7" and quickly take care of the slow-moving grubs - like Japanese Beetle grubs and chafers - that inhabitat the deeper layers of the soil. They like warm soil; when the soil temperature drops below 68 degrees F, Hb becomes less effective.

General usage
Use on lawns, in flower and vegetable gardens, fields, orchards, and greenhouses.

Directions for use
Use a hand sprayer, hose end sprayer, or pressurized back-pack sprayer, depending on the size of your area.
Nematodes are neutralized by exposure to strong sunlight, so they must be applied in heavily overcast or rainy conditions. Dusk or during rainfall is an ideal time. Nematodes prefer a moist environment. If the ground is very dry, it helps to pre-water the area you want to treat.
For more information, see detailed instructions.
