• Beneficial nematodes, best suited for mobile pests that include fungus gnats, ticks, thrips, leafminers, caterpillars, cutworms, sod webworms, onion maggots, subterranean termites and more. Nematode products can be applied to the soil through conventional sprayers or through the irrigation system.

• Roughly 1 million nematodes per 1000 square feet of soil medium.

  For each square foot you will need 0.66 gallons of water as a carrier to saturate a potting medium or soil 2” deep.

• Unless using your nematodes immediately, store in a refrigerator at 40. Do not freeze!

  When applying, use cool water, and do not apply during hot dry conditions.
