A conical-shaped plug member integrally comprising soft, porous foam material and having a helical profile for plugging the gap space in between the flights of an auger when an auger is not in use. Helical auger plug systems may comprise a removably attachable flag to indicate when the plug member is in use (inserted). The plug member of the present invention is designed to reduce the loss of heat (or cooling air) within/from a grain bin during the heating and drying process while preventing rodents and other animals from entering the grain storage bin through the auger flightings and infesting the grain.
