Upping the power could be quite effective.
I run a 100w laser cutter for various projects and over this summer we had quite a few wasps coming in & out of the building.
I can confirm that at 50% power a wasp flying through the unfocused beam loses the majority of it's wing surface (and ends up walking)
at 75% power a wasp flying through the beam ends up as several parts of wasp and a puff of smoke
Biting the hand that feeds IT
