These microscopic organisms destroy pests that live underground. They will seek out and destroy more than 230 different kinds of soil dwelling and wood boring insects, including Japanese beetles, cut worms, wire worms, weevils, white grubs, fungus gnat larvae, flea larvae, subterranean termites and many more. They move through the ground, enter the body cavities of their target pests and release bacteria that kill that pest. They are completely safe for people, pets, and the environment, and are compatible with other beneficial insects. Each container includes seven million live beneficial nematodes.
