Orthene, used according to directions, can be applied to pastures, roadsides and various trees and shrubs. Orthene cannot be applied legally to Garden crop foods. On vegetables and fruit, use other insecticides strictly according to label instructions. Baits are easy to apply, usually effective, and have little effect on beneficial Insects. Disadvantages include slightly higher cost and less availability.
Scatter baits early in the morning before grasshoppers start to feed.
In recent years, there has been considerable interest in a biological control disease organism, the protozoan Nosema locustae , for grasshopper control. In situations where grasshopper problems are imminent, Colorado State University entomologists do not recommend applications of N. locustae alone. These applications do not provide rapid control of grasshoppers. This protozoan is not effective against all grasshopper species and is much more effective against young grasshoppers. N. locustae applications may cause some reduction in grasshopper numbers in a few days or weeks, but in general it is a slow-acting and debilitating disease of grasshoppers that takes at least a year to affect grasshopper populations.
