Japanese beetles are one of the most destructive garden pests. As adults, they ravage your flowers and vegetables. As young grubs they devour your lawn's root system, and they attract skunks and moles. Grub Guard beneficial nematodes are naturally occurring microorganisms that live in the soil, feeding on Japanese beetle grubs. Unlike chemical controls, they won't harm earthworms or most beneficial insects, and they are safe around pets.
