Grasshoppers

Chewing pests

Grasshoppers have long hind legs that are adapted for jumping. They tend to feed during the day, creating large, ragged holes in plant leaves. High numbers of grasshoppers can cause extensive plant damage within a short period of time. They overwinter as eggs in the growing medium.

Adult grasshoppers are typically 2 to 5 cm long, and they vary in color from brown, green and red to yellow, depending on the species.

Management

Grasshoppers are difficult to control with spray applications of contact insecticides because they are strong fliers and highly mobile. One option is to place a covering over plants until adults are no longer present. Remove weeds from adjacent areas.
