Hi, i found this: "Hot Pepper Wax Insect Repellent is a natural garden/greenhouse spray repellent and insecticide. It is proven effective against aphids, spider mites, whiteflies, lace bugs, cabbage loopers and beet army worms for 2 weeks or longer. The chief active ingredient, CAPSAICIN, is an extract from cayenne pepper." http://www.hotpepperwax.com Who knows it, and has experience with it ? Best wishes from Germany!
