About Grasshoppers

Wherever you find grass, you will also find grasshoppers, and a few of the hundreds of grasshopper species found in North America can be major garden pests. Cool, rainy summers cause many grasshoppers to fall prey to disease, while hot, dry weather can lead to major grasshopper headaches. 

Grasshoppers weaken plants by removing plant tissue, and they are especially damaging to lettuce, beans, corn, carrots, onions and cabbage family crops grown for fall harvest. Organic controls for grasshoppers include excluding them with row cover or screen barriers, controlled poultry predation, and inoculation of the soil with microorganisms that kill young grasshoppers. Grasshoppers are found throughout the world, and are most problematic in areas where wild grasses dry up in summer, causing the hoppers to move to lush, moist gardens.

Ancient insects that have inhabited Earth for more than two million years, plagues of grasshoppers have been responsible for many famines. More typically, grasshoppers fly into gardens in late summer and chew up plant leaves.
