Orthene PCO Pellets are still one of the most effective concentrates to use for roach control. As a wettable powder, it does a great job of staying on top of treated surfaces which insures target pests receive maximum exposure when they enter treatment zones. Additionally, Orthene still shows little to no sign of insects building resistance to it making it a solid performer.
