Grasshoppers normally do not bite, but they do have powerful jaws and a small nip is possible if the insect is defending itself. But there is no venom in the bite, and grasshoppers are not considered dangerous insects. Bites, if they happen, should be cleaned, and any residual itchiness can be treated with a calamine or cortisone lotion. The skin sensation caused by the sticky, spiky hind legs of a grasshopper is sometimes mistaken for a bite, but this prickly sensation is generally entirely harmless.
