You can expect to see grasshoppers peak from June until about October. The potential for grasshopper damage increases as summer progresses. Adults will be more likely to move into yards and gardens in July and August. Severe problems may arise when adjacent agricultural crops and grasslands mature or are harvested and grasshoppers move to find new food sources. They are most active during the day as they are attracted to light, however they also feed at night. Grasshoppers do not have nests or territories, and some species go on long migrations to find new supplies of food. They can eat a wide range of plant matter, though they’re especially attracted to alfalfa, corn, clover, grasses, and small grains. / SANDRA JAMES
