We do sell many different kinds of insecticide dust. The only one that we sell that has both pyrethrins and piperonyl butoxide is Drione Dust. This should only be used in cracks and crevices. For the most complete roach control, we recommend our Roach Control Kit Rotation A. This kit contains all the products that we recommend to use together for roach control: an insecticide concentrate, and insect growth regulator (IGR), and roach bait gel, and glue traps for monitoring. Please see our Roach Treatment Article for more information and tips about roach control.
