We do the same thing with the bugs, except since we're running off-grid with just a few solar panels we have to watch our wattage (you'd be surprised how much power some things suck). So this is what I've done. Just an LED over a tub with a couple inches of water and a bit of cooking oil. The oil makes sure the bugs that are light enough to land on water and fly off get stuck instead. Leave it out all night and the girls can have breakfast in the morning.I put Mosquito Zappers in the coop, they weren't bothering the chickens (pre naked neck owning days) and every time I went in to check their feed I would wack the bug zapper to make the bugs fall out and the chickens would come running over to have fried bugs. To be honest it seemed to attract every flying insect except Mosquitos. I had it for a food source for chickens more than anything.
The downfall is it does catch some beneficial bugs. Like damselflies and preying mantis'. I always feel sad when I see a Mantis' in it....
