Ok I'm fed up with those cockroaches. I've had enough. Im going to set up a tank where I'll keep cockroaches under otherwise normal conditions - water bowl, some sugar cubes, etc. With a slight catch of human touch from above - I'll have a germicidal lamp on 24/7 on them. A 254-nm UVC light source covering pretty much entire surface of the tank My question is - how fast will they die? Will they die at all? Mutation? Or perhaps just a chipping away of their exoskeleton?
