NemaSeek Hb (Heterorhabditis bacteriophora) Beneficial Nematodes seek out pests living in the soil. 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 developing (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. They are completely safe to use and will not affect mammals, aquatic life, birds, reptiles or amphibians. After application, the nematodes immediately get to work. Upon finding a pest, they can enter it through various body openings or directly through the body wall. Once inside, it is not the nematode that actually kills the pest, but the toxic bacteria inside the nematode's gut that is the real weapon - symbiotic bacteria, that when released.

These nematodes are adapted to all climates but should not be applied until after the last threat of frost. Prefers a soil temperature of 65° F.
