Beneficial Nematodes (Steinernema feltiae) are microscopic in size and cannot be seen with the naked eye. They attack more than 230 kinds of soil dwelling and wood boring pests, such as flea larvae, white grubs, cutworms, corn root worms, strawberry weevils, gypsy moth larvae, cabbage root maggots, fungus gnat larvae, and many more before they emerge from the ground in their more destructive adult stages.
RELEASE: Beneficial Nematodes may be released by spraying with water, mixing with mulch and applying directly to the soil or potting mix, or injecting into burrows. They may be used any time of year, as long as the ground is not frozen. Do not release in direct sunlight, as this will kill them. See directions for details.
COVERAGE: Our container of 7 million live Beneficial Nematodes will cover up to 2,000 square feet, but faster results are obtained with higher concentrations.
Beneficial Nematodes hunt down, penetrate, and kill most soil dwelling pests. They will remain effective for about 2 years, but annual applications are recommended. They will also attack over wintering adult insects, pupae, diapausing larvae, and grubs when they are in the soil, bark, or even ground litter. They do not affect humans, animals, or plants. They are completely compatible with beneficial insects such as ladybugs, lacewings, and praying mantids and do not harm earthworms.
