Haven't tried, Mike, but I did smack a wasp while I was trimming Arborvitae today . . . didn't kill it, but pissed it off & grounded it (evidently they can't fly with shredded wings). Moths might be a possibility on the wing since it would be fairly simple to establish oneself within 3-feet of a light at night, but it would still be quite a challenge (not that I've planned such entertainment for a future warm summer night . . .).
