Beneficial Nematodes Control Soil Dwelling Pests

Use Beneficial Nematodes to Control Grubs, Fungus Gnats, Fleas and Over 200 Other Soil Developing Pests!

ARBICO's Beneficial Nematodes are live microscopic organisms (non-segmented round worms) that occur naturally in soil throughout the world. They are parasitic to insect pests that typically have a larval or pupal stage of life in the soil; however, they have been known to also parasitize above ground stages of adults, nymphs and larvae.

Beneficial Nematodes can be used anywhere developing pests exist including backyards, flower and vegetable gardens, lawns, fruit and nut trees, vines, greenhouses, row crops, pastures and more. Use the beneficial nematode selection charts to find which species of nematode controls the pests you are dealing with.
