Aha! I found a grasshopper spray using natural ingredients.


HOME MADE CHILLI SPRAY

Blend together half a cup of fresh chillies with 2 cups of water. Add a dash of dishwashing liquid to improve sticking. If you have no chillies substitute with 2 tablespoons of Tabasco sauce. Always spray a small section of the plant to check for leaf burn. Check in 24 hours and if there is no damage spray all the plants you want to protect. Leaf burn with any spray is more likely to occur during hot weather.

That site also suggests a garlic spray, but doesn't tell you how to make it. There are other non chemical suggestions listed as well.

Another option is to make a bait. That same site says to use Canola Oil as a grasshopper attractant It's used to make baits more attractive to grasshoppers, combined with organic insecticides to make them more effective and floated as an oil on top of water traps.

Good luck.
