Occasionally, we here in South Florida have similar moments, where we find the need to hoist the black flag, or Raid, depending on what's handier at the moment, and spray.
Take flying cochroaches. Please, take all you can, we got plenty. 2+ inches, and friendly as heck. Not afraid of the light anymore, reckon that was genetically mutated out of them with the advent of modern electrical lights.
But it was the "slitting throats" reference that threw me, though. See, slitting a roach throat wouldn't do a lot, 'cept to make it harder for 'em to swallow for a while. Ya'd have to stab the buggers along the sides where the spiracles are, cut off their breathing. Can't go for the brain, either - it's splayed along the belly side. Cut off it's head, you'll numb a bit of the nervous system, that's all. Besides, last time I tried, the doggone thing ran off with my kagas katne.
But I found out I'm Class 3 qualified, and am in the process of procuring a suppressed Ruger 10-22 w/laser aiming module. That'll impress the little buggers!
If I can find out where they hid my box of .22s.....
