I may have missed a thread on insecticides last week whilst abroad but I use Marathon (imidacloprid) for virtually all my interactions with things that suck and crawl. It is a superb product, contact and systemic, lasting for up to 6 months, dependent upon compost. Two summers ago I found quite a few mealy bugs on some dormant Narcissus, Scilla and Leucojum I had acquired the previous year and have used Marathon since then, the main coverage being a treatment in March. I've never seen a beastie on them since and never had healthier bulbs either. I also use it on my irises outside - oncos and junos - in fall and early spring J.
