If they are using bug zappers to kill moth pests, I'll bet they do work.
The fact that so many people still use them to rid their yard of mosquitoes would suggest that the people using them are seeing some evidence of their usefulness. For one, they hear the "ZAP" - music to the ears of the suburban mosquito warrior. Because the unit they bought is called a mosquito zapper, that's what they assume is getting fried.
Secondly, they also see deep piles of what they believe to be their quarry at the bottom of the unit the next morning. The truth, however, is most people can't tell the difference between a midge of the Chironomidae family and a mosquito, which can look very similar. The midges do go to lights - in great numbers! I discovered this over 20 years ago, when I was duped into using one of these ridiculous things. I remember seeing with great pride and satisfaction the pile of hundreds of dead "mosquitoes" at the bottom of the tray. I thought this must be making a difference in the population - that's hundreds less who will be laying thousands less eggs - and that's just one night. Then I looked more closely, saw the very feathered antennae and lack of a probosci. Couldn't find a single mosquito among them.
Fortunately, some people do discover they don't work, which makes them easy to find, pretty cheaply, at yard sales. As I mentioned in the previous posting, once the electrifying grid is disabled, they make great moth lights!
