Oh I know how that goes.....They were all over my garden last year. I easliy had 20 to 30 Cucumber Beetles on every blossom. I had always been organic in the past but finally had to resort to Seven Dust. They were eating everthing. This year I changed a few things. I put my gourd plants out later, made many yellow plastic traps coated with tanglefoot paste, planted the right kind of Marigold. I have tried marigolds in the garden for years with no luck. Finally I read the hybrid marigolds had the smell bred out of them, no wonder they didn't work. I planted African Marigolds, Tagetes erecta and boy do the stink! It's wonderful! I have seen very few beetles this year. I still go out a kill what I see by hand but I maybe killed 5 tonight. I am also trying a recipe for a organic spray that I found on another garden forum. It does kill them but I've had so few this year that I've only used it a couple of times. But this is the recipe: Add 1 teaspoon of dish soap(not aniti bacterial) to a quart of warm water. Add 1 1/3 ounce of Neem Oil, 2/3 ounce of Karanja oil and mix well. It will look milky. Add this to 1 3/4 gallons of water, mix. You now have 2 gallons of spray solution.Pour into a sprayer of any type and spray on the plants, undersides, stems and ground. It may also be used as a soil drench. Use 7-11 day intervels, 4-5 times a season. At this ratio it is also good as a fungicidal application. I also dicovered squash bugs on my egg gourds the other day. I put neem meal around the base of the plant and boy, they took off running. I also sprayed them with this solution and I didn't see any tonight.
