Several years ago, I had a great idea (IMO). Since my problem is a moth, and we know moths are attracted to lights, maybe they could be controlled with bug zappers. I wanted to give it a try, but the pines are far enough from the house that providing electrical power for the bug zappers would be a hassle. Last summer I saw an advertisement for solar-powered bug zappers. I ordered four. I didn't received them last summer; they were back-ordered. Six months later, in the middle of the winter, weeks after I'd given up ever receiving them and had forgotten about them, they arrived.
I 've installed them. They look like normal solar-powered garden lights except around the light is a coil of wire. The light, an led, is blue, biased toward the ultra-violet, I suppose. The zappers appear to be working. I watch from a distance, and every so often, the blue light flickers and dims like the proverbial light at an execution.
