How it works
After release, the Hb 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, they become less effective.
The Sf nematodes stay in the top 1-3" inches of soil. Both species act by invading grub or larval bodies and by then releasing bacteria that are deadly to the grubs or larvae. Death usually occurs between 24-48 hours. The nematodes can produce up to 3 generations during the following 3 weeks and they thrive until the grub/larval infestation is severely depleted.

General usage
Excellent for grub problems in lawns, greenhouses, field crops, orchard crops.

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.
