I was looking at my bug zapper in the garage and it dawned on me, the worm making monsters minus butterflies come out at night! I had a round of worms on my Tomatoes(they ignored my peppers) a few weeks back, had to seven them as a last resort. I put the black light bug zapper about 50 feet away, now lots of moths, and several other species are getting zapped. Meanwhile the toads(they camp under the light) are gettin real fat. I had an issue with those little nats that produce root eating maggots on my patio, I hung a bug strip under the light, the nats go up to the light and get stuck. I still have some nats, but nowhere near the previous numbers. As for the black light zapper, no new worms so far; I'm keeping my hopes up.
