Getting rid of the pecans would be the first thing and it sounds like you have done that. Treating the room with a residual insecticide such as Demand CS might help. Fogging the room with CB-80 will also help. Sometimes things like this don't have an instant cure, they just have to work themselves out. These critters can hide in all sorts of nooks, crevices and crannies. Repeated treatments over a several week cycle will get rid of them.
