Several years back I read where some organic gardeners wanting to get away from harsh chemicals were mixing I believe 1 TBS of dish washing detergent/soap, to 1 gallon of water. Seems some prefer Ivory brand.
I just Googled it again, and this spray is mostly a direct contact bug killer. Theories why it kills them is either it cuts through their waxy exoskeleton, or neurlogical breakdown.
Haven't tried it myself, but once I have time to care for a garden again, I'm definitely going to try it.
I heard the same on a radio call in show last week. Add 1 part dish soap to 99 parts water. Spray directly on beetles. Must make contact to kill so only spray if you actually see the beetles. Most years I walk up the potatoe rows and hand pick all the bugs I can find.
