There is a small moth that gets in the house from time to time. I strobe them and they land every time. WHACK! No more moth!
Found it! I knew I read this somewhere.. Thank you, thank you.
Tonight, one of those giant flies made it into my home - you know, the really fast loud-*** cruise missile types that buzz an entire room back and forth and you can barely keep your eye on them for more than a second. Anyways, tried the strobe on him in a brightly lit room and didn't notice any effect, but then flicked all the lights off, tracked him by sound, and then nailed him with my 1,000 lumen thrower's strobe and down he went... Shoot'n fish in a barrel!
Don't know if it was a one-off coincidence, but I will certainly be experimenting further (keeping fingers crossed).
