Heterorhabditis Bacteriophora Nematodes (HB)
Are most effective against Japanese Beetles, Grubs, Weevils, and many other target pests in lawn and garden. They burrow down in the soil to a depth of 7", have shown superior host-seeking abilities in looking for deep soil- dwelling pests.
Target pests include: Cucumber Beetle, Grubs, Gall midge, Strawberry Rootweevil, May/June Beetle, Masked Chafer, Cranberry Rootworm, Flea, Scarab and Japanese beetles, Straw- berry Root and Black-vine Weevils, Chafer, Squash Bugs, Leaf Beetles, Termite, Cutworms, White Grubs, Algae Gnats, Black Fly, Potato Tubeworm, Meal Worm, Bark Beetle, Corn Root Weevil, Fire Ant, sting Bugs, Pine Beetle, Gall Gnats, Gypsy Moth, Corn Root Worm, Billbug, Colorado Potato Beetle, Thrips, Ants and termites (apply directly to mound and nest areas),and many other deep soil dwelling insects.
They are highly efficent when the pest is more widely dispersed in the soil because they have a "tooth" to rupture the insect's skin and enter through the insect's body wall and openings.
Steinernema Carpocapse Nematodes (SC)
Kills pre-adult fleas in the yard, and pet run areas and soil. It's most effective against flea larvae and caterpillars in lawns, garden soil, and under trees where larvae pupate. They stay near the surface waiting to ambush surface dwelling pests. Steinernema is the most widely researched species for insect control. It is the most readily available for yard and Garden use because it is easier to rear and handle. In field applications, Steinernema carpocapsae tend to be most effective against caterpillar larvae. In laboratory and field trials, it has controlled sod webworms, cutworms and certain borers (raspberry crown borer, carpenter worm). It also has been effective against billbug larvae in Colorado State University trials. Other research indicates that adult billbugs may be controlled as well. Steinernema are less effective against white grubs, root maggots, rootworms and black vine weevil. Unfortunately, some commercial products make claims of effective control of some pest species based on research conducted solely in artificial environments; these often do not reflect performance in the field.
Target pests include: Fleas, Dog and cat flea larvae, Codling Moth, Cutworm, Armyworm, Leafminer, Bluegrass billbugs, termites, ants, Sod Webworm, Mole Cricket, some caterpillar pests, Billbug, Flies, ArmyWorms, Loopers, European Crane Fly, Cranberry Girdler and many other surface dwellers.
Steinernema Feltiae Nematodes (SF)
Are the most effective against larval control of several fly species (sciaridae, phoridae, leaf miners, domestic fly and also of some moth larvae. They patrol the top 3" of the soil.
Target pests include: Fungus Gnat, Mushroom Flies, Fruit Flies, Flea Beetles, Saw Flies, Tachina Flies, Crane Flies, Shore Flies and fruit flies.
They are effective against some plant parasitic nematodes, particularly root-knot nematodes.
