Hi all, I have orchids and African violets living together in harmony in my sunroom. I recently noticed a few thrips on some of the violets. I've started treating them with Bayer Tree and Shrub (Imidacloprid) as a drench. I've ordered some Avid to spray as well. I assume I should also be treating the orchids, though I haven't yet seen any bugs on them. How best to treat them? Alternate spraying with both, use the Imidacloprid as a drench and spray with the Avid, or something else? Will the spray affect the flowers? I have a few in bloom and in bud right now, and I'd hate to ruin the flowers with a spray. Thanks.
