I too live in Texas (West) and have never had bugs or roaches in my fabric. However in the very hotest of the summer, you can see roaches or water bugs, outdoors in the grass and they have come onto the patio. A friend who had lived in South Texas told me 30 years ago to be sure to keep the stoppers in the sinks and tub in the summer, because the water bugs live in the sewer and crawl up the pipes, gives me chills just thnking about the nasty things, this was her remedy to keep them out. Get a jar of Boric Acid and some peanut butter use about 2-3 tsps of peanut butter and about 1 tablespoon of BA and mix together, then put a dab of this on an inch or two piece of tin foil and put under cabinet area of sink, and anywhere you think they might be.You need to replace this about every 6 mos. I keep some out on the patio, behind things, near baseboards, under bathroom and kitchen cabinet areas, near hotwater heater, and under washer. So far this has always worked. I don't really measure this and I use a toothpick to stir this up or a popsickle stick and put it on the tin foil. I've never had the little brown roaches, just had those big water bugs and have used this BA & PB ever since.
