In TX, I broadcast spread the yard with ant stuff and never had any issues in the house because of it. I'd put a "double dose" close to the house and the rest was as directed. Unfortunately, I'm not in TX any more and don't remember the stuff I used. I got the stuff based on a recommendation of a local farm supply store and it seemed to work great. Any good suggestions here in Tulsa, or a place to go who will make a solid recommendation (not just the most expensive thing they sell)? I'm not really seeing them IN the house but man they are all over the foundation so I assume they're probably in a wall somewhere.
