Here are a couple less toxic solutions you can use for bugs that I think I found here on ATP:
Murphy’s Oil soap solutions for gardening:
Daylily Thrips:
¼ c Murphy’s to 1 c water; spray buds when they first come up. Also spray rebloom scapes.
Iris Borer:
10% Murphy’s in water; spray entire plant.
I haven't tried it for thrips, but it does work for the iris borer.
