There are also numerous grasshoppers around field borders and in waterways/pastures, etc. These grasshoppers are still small so now is the time to treat these areas if the populations are sufficient to warrant it, approximately 20 per square yard. They do not yet have the ability to fly, thus are still contained in these smaller areas where they are better controlled without spraying larger areas of crops.
