>>Depends on the disease. I used Clorox solution last year on nosema ceranae spores but I had deadouts this spring with high spore counts in many of those same boxes so I am going to fumigate with acetic acid ( like used in Europe) this spring. Would you still treat if the beeless frames had been through a cold winter. Someone, Randy I seem to recall, mentioned the cold kills the spores though I am not sure how cold and for how long is needed. >>A slight warp can * at times * be reused. I have too burn barrels outside my shop and I burn warped plastic foundation and there is little left. I once leaned a couple of Pierco frames against a hive for the bees to clean up and did not take them out of the sun in time. They warped. Anyone have a tried method to unwarp plastic frames. I thought about clamping them down against a sheet of plywood and softening the plastic up to unwarp in the sun this summer...
