I'm done with creating noxious gases out of pool chemicals.
I'll try some dog poop in each hole tomorrow.
Then, I'll move on to flooding them out.
If that doesn't work, a road flare or two may smoke 'em out.
And, if that still doesn't work, I might move on to the exhaust
gas method; but that actually kills 'em, so, I prefer not to move
forward to traps which do kill 'em fer' sure.
