div><br class=3D"webkit-block-placehold not Ian, but having gone through that, we now store seed either in the deep freeze or in the barn. There are traps, I got mine at Spencer's in Shelburne where they had a terrible time with them. those little moths or larvae can get into and (very important) out of absolutely any container......in the cracks of old floorboards even hardwood and in the joins of gyprock....what a time we had with them. We nearly stopped feeding the birds altogether! How should one do that stop by the way, if they are moving or unable to keep it up.......
