I'm not - mosquitos, bees and wasps don't seem overly concerned with my wellbeing either... zap the buggers!Are people really worried about being cruel to flies, and wasps?
I was going to say, if you can shoot a fly out of the air with a laser you are a master laser wielder. But yeah...kinda borderline sociopath if you like killing insects with lasers...well... I have had some experience with wasps, not a fly specifically. I found that it was relatively easy to take the wasp out of the sky, but it did not die very fast as it kept moving out of the beam.
So it's not really a practical solution for shooting down flies and I felt kinda bad that the wasp lived as long as it did when I was trying to kill it. You're better off with a fly swatter IMO. Using the laser just seems to be overly cruel as it just isn't fast enough.
