I have Japanese Beatles devouring my Roses & Zinnias as well as other plants & trees. I have been using a homemade Insecticide spray which consists of: 8oz. 3% Hydrogen

Peroxide, 8 oz Sugar, 1 tsp MurphyÂs Oil Soap, mixed in 1 gal water. This spray worked great to kill the worms on my broccoli plants, but the Japanese Beatles is another story. :( When I spray the pesky bugs it seems to temporarily prevent them from flying. I can then pick them off and drop them into a bucket of soapy water, where they ultimately die. Has anyone found something better? I donÂt have all day every day to stand guard of my plants against this enemy! I also have been concerned about the effects of to much Hydrogen Peroxide on the leaves of some of the flowers. I donÂt want to resort to non-organic measures but I donÂt want to loose my Roses etc.
