Mary Sue: I scanned through the article, which is very helpful. I seem to have heard somewhere or read somewhere that vegetable oils can be used as a spot spray on the foliage base to help with control... As a matter of fact, I just found an article that refers to canola oil and pyrethrins as a drench, "http://davesgarden.com/guides/bf/go/2436/", but I know this is not the source I have in vague memory. Anybody had any experience fighting the Narcissus fly organically? Mr. Kelly M.
