The red flour beetle is a common pest in graineries and flour mills as well as homes and businesses.  Originating from infested grain, the adult beetles often wander away from the infested material and may be found inside cupboards or anywhere in the home or business. The rusty red beetle is found frequently in stored wheat thus an infestation may be evident in bagged flour, cereals and other processed grain products. The eggs are deposited on the grain and after hatching the larvae usually feed in the germ layer of the wheat kernel.   This insect does not require broken kernels or fine material to survive. We treat these in grain bins by fumigation.
