Funny enough, the other day after having an encounter with a flying cockroach I wondered about using lasers to kill those. I imagined just finding a decent power rating laser diode a consumer can buy, driving it to the max and seeing what it could do.
Unfortunately it seems that any beam focused/powerful enough will end up damaging anything else it hit (in my case: walls, ceiling, carpet, etc.)
Yeah but when the choices are do something you hate for a moderate amount of money or do something you hate for a ton of money, the second option is at least marginally better. Hell at some of those salaries you could probably even retire early.
