This reader asks about the “locust,” which is a term often colloquially used to refer to two very different insects: the periodical cicada and a grasshopper-type locust. colonists were familiar with the Biblical story of locust. “Do you have any tips for dealing with the locusts that have already started to arise from the ground this summer where I live in southern Ohio?
