I don't think Sevin will help since it is a stomach poison and works mostly on chewing insects but a strong dose of permethrin and soapy water will get the ones it hits and so will Malathion. I sprayed a couple of times when the thrips were coming in really heavy and it did seem to clear a lot of them out but that was well over a month ago. I have only seen a few sporadically since then and have only had about one more infection every 10 days or so which with the number of plants I have set out is not a major problem.
