Yes, this is a serious question, not a joke. When I first began using red pepper flakes and cayenne pepper to deter our local pests (rabbits, javelina, deer, pack rats et al) I didn't think a thing about whether the flavor of the zucchini, green beans or tomatoes would be affected.
After two weeks of constant applications, I'm not quite so certain. The peppers are doing their job, so far, and I would hate to give in to the beasties. We've walled & fenced, covered open places with boards but there is no way, short of a bubble environment, to keep out rats who climb vertical walls. The peppers are doing the trick but if we can't eat the final product, it is senseless. So, does anyone who has used these products know if I'm growing spicy vegetables?
