The program helps contain grasshoppers on rangeland and also targets a close cousin, the Mormon cricket. The ranch was recently treated with insecticide to avoid being menaced again. According to Rogg, agricultural losses due to grasshoppers are often reported to be in the hundreds of thousands of dollars. In addition to grazing down rangeland forage, which also wipes out feed for wild antelope, grasshoppers eat the leaves off of fruit trees and bed down in the dry areas ringing crops, where they decimate grain by eating slowly inward.

Capable of flying for miles, they can travel in bands to consume one area, then move on to the next. But controlling grasshoppers can be challenging. Because they molt like snakes, shedding skins as they grow, they are susceptible to the most targeted insecticide, dimilin, only when young and between molts. That window is small in places like Oregon, where grasshoppers tend to hatch early and mature fast, in part because the climate crisis is hastening the timing of their hatch.
