Adults do live up to 24 months so heavy infestations may require a residual crack and crevice treatment in voids or around shelving. Many manufacturing facilities have gone to great lengths in designing and engineering equipment and plant areas to accumulate as little dust as possible and to allow easy access to clean. Infestations have been traced to grain dust in light fixtures, candy machines and in voids in conveyer belts, and other equipment. Plants should inspect and reject any commodity that is infested before it gets off the loading dock. Food plants and warehouses will target their pest control at prevention.
Pheromone traps are available to monitor and constant inspection is needed to spot problems early.
Space spraying and residual applications in key areas should be considered in sensitive areas, and there are examples where hole buildings have been sealed and fumigated to control flour beetles. All life stages are killed when exposed to temperatures of 0 to 5 o F for one day.
