There are many varieties of grasshoppers across the United States. All pose a nuisance to the home gardener. Most grasshoppers enjoy eating predominately grasses and broad-leaf plants. As nymphs and young wingless grasshoppers they tend to reside close to where they were hatched until the food supply is exhausted. Soon the adult grasshopper has wings and can travel many miles in search of sustenance. Home gardens are a favourite location for feeding grasshoppers. Many households hesitate to use pesticides on their home vegetable sources and are turning to a variety of safe, organic control methods.
Mix one part apple cider vinegar with three parts water and add 5g of pure soap flakes. Pour the mixture into a large insecticide sprayer.

Wait two days and then repeat the application. Continue until the grasshopper infestation has significantly diminished.
Pick up the dead grasshoppers in your garden. Place the dead grasshoppers in a garbage bag and promptly dispose of. Birds will dine on many of the dead grasshoppers in the garden but the vinegar mixture will not harm the birds.
