If you were living in NYC( Heaven forbid) you’d need a .38 to kill a roach. The things are as big as mice. I’m not kidding.
Southern roaches make up in numbers what they lack in sheer size.
Walk into kitchen at night in our old fleabag apartment, turn on light . . . "Hey, honey, I didn't know we had brown linoleum . . ." YEccccch!
