I'm not - mosquitos, bees and wasps don't seem overly concerned with my wellbeing either... zap the buggers!
As for the 1W 445: I havent tried that, but perhaps that would kill them instantly as well. Be careful what you hit while chasing after bugs with those, would be to bad if you have your house covered in burnmarks from near misses
Electric rackets really are a better way to kill bugs.
Probably the best way to do it with a laser would be with a quick computer tracking system and a laser of a wavelength readily absorbed by flying insects. If the system is also advanced enough to measure how far away a bug is, then it could focus the laser on to it. If it was powerful enough, there'd be very little bug left to hit the ground
