Hi Polly, yes I did try that, both under my lights and out in the greenhouse. Results were mixed... a few gnats/whiteflies wandered into the traps but I think the yellow sticky strips were more effective. I don't know how it might work with aphids since I just recently discovered them. I didn't even know I had them since they hide on the underside of the leaves. They must have come in on some other plant that I bought and put under the lights. I just wish the foliage would die back so I can clean it all up. But living in a little banana belt here that may not happen at all for some of my seedlings.
I like all that science stuff too
