A much better starting point than trying to zap mosquitos in flight. Cover small 2d areas rather than large 3d volumes, and bigger targets. Rats would be easir

A much better starting point than trying to zap mosquitos in flight. Cover small 2d areas rather than large 3d volumes, and bigger targets. Rats would be easir still, but you would need a serious laser for them, so get it right on the cockroaches first. This could be very useful for guarding entries to commercial kitchens and other food manufacturing facilities.
