It’s like a biblical plague. The roads in some parts of western Montana are slick with grasshoppers. And there’s nothing to do but wait it out. “There’s a lot of places I’ve seen where you can’t tell whether it’s ground or grasshoppers,” Mike Chenoweth, a weed control agent, tells the Missoulian. Blame the dry spring and wait for the temperatures to drop, he advises. Or, as the county horticulturist says, “We’ve got another four to six weeks of grasshopper hell.”
