Roaches are a fact of life in Texas. They don't bring the same stigma they do in other places, here they live in even the cleanest of homes. That doesn't make living with them any fun though.
Since fashion tastes changed and you can't hardly find roach killer boots anymore...
...I've resorted to an annual to semi-annual bug bomb do-it-yourself-fumigation, followed up with boric acid use. The fumigation kills 'em dead, and the boric acid gets those you missed and any that want to move in later. I also toss out a couple of those bait/poison gizmos in the dark recesses of lower cabinets, etc.
Just fumigated a few weeks ago, which was my wife's cue to bring home some boxes full of old photographs from her dad's garage. She plopped them down in the bedroom and ten minutes later she's screaming for me to come kill a roach. I'll admit to being confused ("thought I just killed these things") until I saw the box of photos and knew how the sucker got in my house. "Thanks dear, I was wondering how we were ever going to repopulate the bugs after I killed the last batch!"
