Are grasshoppers poisonous

It can hurt, and allergic reaction to the saliva is not unknown. Barring allergic reactions, express (or press) some blood from the wound. Then treat with an antiseptic like hydrogen peroxide 3%, bandage and wound check it either daily or if complications arise. Shortness of breath, the appearance of hives, welts or weals in large numbers, extreme itchiness all mean you're allergic. If you ever have a breathing problem, it's off to hospital for you. Likewise with huge, fast-appearing rashes. Minor rashes may be treated at home with antihistimies -- I still like diphenhydramine.
