|How do I get rid of grasshoppers in hibiscus plants outside ?
|There's a biological control called Grasshopper Bait. It's a product made from bran and a sweetener lure, laced with a predacious protozoa called Nosema locustae. It is non-toxic to animals, people, plants and other insects, but kills most species of grasshoppers by infecting them with a disease. Grasshoppers will spread the disease among themselves, by eating sick hoppers and by laying infected eggs.
