Thanks to everyone who purchased nematodes from UPDC this past summer. All proceeds went to Union Park District Council! The grub stage of Japanese beetles eat roots and destroy lawns. The adult beetles skeletonize numerious plants such as raspberries, morning glories and roses. From the manufacturer: "Beneficial Nematodes, Heterorhabditis bacteriophora, actively seek out pest insects in the soil. They are live microscopic organisms (non-segmented round worms) that naturally occur in soil throughout the world. The beneficial nematodes we sell are parasitic to insect pests that typically have a developing (larval or pupal) stage of life in the soil. They have been known to parasitize above ground stages of adults, nymphs and larvae. They will not harm mammals, aquatic life, birds, reptiles or amphibians. After being applied to the soil, the nematodes locate pests and enter through various body openings or directly through the body wall."
