Grasshoppers are large insects, often up to 2.5 inches in length, and they come in a variety of colours, including light green and brown. Their very large hind legs, designed for jumping, easily identify them. There are hundreds of varieties of grasshoppers. Most are not harmful to either trees or plants and, in most years, they cause no harm, so no steps are required to control them.
Occasionally, in optimum weather conditions, the grasshopper population can swell dramatically. As their numbers swell, they become less selective of their source of food and begin to consume the leaves on every tree and plant in their path, causing massive damage.
Recommended Steps to Control Grasshoppers
When dealing with only small numbers of grasshoppers, handpicking often eliminates the problem. To eliminate large infestations and minimize damage, control grasshoppers when they are in the juvenile stage by spraying the area with Bug Buster Pyrethrin Insect Spray. Repeat the spraying every seven to ten days, as needed. More frequent sprayings may be required to control adult grasshoppers.
