Spinosad is a relatively new insect killer that was discovered from soil in an abandoned rum distillery in 1982. Produced by fermentation, Spinosad can be used on outdoor ornamentals, lawns, vegetables and fruit trees, to control caterpillars, thrips, leafminers, borers, fruit flies, and more. Spinosad must be ingested by the insect, therefore it has little effect on sucking insects and non-target predatory insects. Spinosad is relatively fast acting. The pest insect dies within 1 to 2 days after ingesting the active ingredient. Will not persist in the environment. Sunlight and soil microbes break it down into carbon, hydrogen, oxygen and nitrogen. Classified as an organic substance by the USDA National Organic Standards Board. OMRI Listed for use in organic production. Controls Moth and butterfly larva including Gypsy moth, codling moth, leaf miners, bagworms, tent caterpillars, borers, thrips, Colorado potato beetle larva, leafrollers, webworms, armyworms, sawflies, gall midges, whiteflies, stinkbugs, harlequin bugs, squash vine borer, fruit flies and more.
