Dimlin, the most specific insecticide is effective only against young grassphopers and between molts when adults shed their exoskeletons to grow. If the window is missed, farmers must wait until next year. In Oregon grasshoppers are hatching early and maturing sooner due to climate change making suppresion more challenging. This year's suppression campaign is recogned to be the largest in 35 years. Left to their own fate, grasshopper bursts die off after predators and pathogens catch up to the population growth. Grasshopper popularity as prey makes them key to ecological equilibrium most of the time, until population density turns them into pests.
