Spray products that control grasshopper infestations include Bug Patrol spray by Safer Brand and Ortho's Bug B Gon insect killer. Another spray product that controls grasshopper infestations is Dupont's Asana XL.
Safer Brand's Bug Patrol spray is organic and contains pyrethrins and potassium salts that kill grasshoppers instantly. The spray destroys the outer membranes of grasshoppers and leaves them exposed, so they dehydrate and die.
Bug B Gon spray by Ortho starts killing grasshoppers within minutes and is safe to use on rose bushes, trees, lawns, and house porches or patios. Bug B Gon controls grasshopper infestations for three months before reapplying is necessary.
