The steps of IPM include hand picking the grasshoppers (or other pests) when numbers are small. Pests should then be destroyed.
Grasshoppers create damage quickly and are difficult to control should they descend on the garden or flowerbed in large numbers. Prepare before you are attacked. The University of California recommends planting a "trap crop" around valuable plants. Border the area with tall grasses and keep them moist to keep the grasshoppers away from the prized garden specimens.
Adding protazoan pathogens to the area where grasshoppers hatch can eliminate problems before they begin. Biological controls consist of natural enemies and predators of a particular pest. Nolo Bait is one such product, working on young grasshoppers for 7 to 10 days.
IPM uses chemical controls as a last resort. The Texas Cooperative Extension suggests using a "homemade bait" that includes the chemical Sevin for control of emerging grasshopper populations. Baits may only be effective for a few days.
