In Florida we have a grasshopper normally refered to as a 'Lubber' by the locals. The thing is 2 to 3 inches long and thinks cymbidiums are delicious. It doesnt kill the plant but the damage is unsightly. They are slow moving so the only control I know is to look for them - pull their heads off and put them in a bottle of kerosene. If you stomp on them the eggs hatch anyway.
Does anyone know another way to kill the things? A shotgun is not an option!
