Grasshoppers are large (1 1/2 inches long), green, and have a wingspan of about 3 inches. They are most easily identified by their large size and their green color. While they are generally harmless, they can attract other pests and bother pets and children.
Grasshoppers are common in the United States and Canada. They are most often found near crops or other sources of food. Grasshoppers can also be brought into your home on food or garbage, or if you leave windows or doors open in the summer or spring.
The best way to get rid of grasshoppers is to eliminate their food sources by thoroughly cleaning your kitchen and bathroom. You can also use commercial fly traps or bait. If you have a severe infestation, you may need to call a professional exterminator.
