If you expect trouble from grasshoppers in your area this summer, check out a unique organic pesticide marketed as Nolo Bait or Semaspore Grasshopper Control. Both products contain spores of a naturally occurring grasshopper disease called Nosema locustae in a bran bait.
The grasshoppers become infected when they eat the bait. The disease is slow-acting but spreads gradually, usually causing about 50 percent mortality after two weeks and reduced hatches the year after application.
