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 are so small that several thousand would fit on the head of a pin! But they do a big job—moving through the ground, they 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.
