I have used Diazanon as well as systemic insecticides other than imdacloprid. I don't know if they were all organophosphates, but they certainly all do smell like dead rats. This makes them unsuitable for indoor use. Anyone know about anything less smelly shich will get down to where the mealies like to hide? Dell in PA where something labeled "Cyrtanthus elatus x falcatus" is in bloom. Also blooming, two weak white crocuses (ochroleucus?) and a pale pink colchicum which I don't remember planting.
