The species name of “stercorea” refers to the Latin name for excrement or dung, a reference to the presence of this beetle in moldy, decaying materials. It is an occasional stored food pest, but would normally infest food products in very poor condition, particularly those in damp condition with fungus growing on them. Adults run quickly and are able to fly.
If these are found within a structure it is necessary to perform a careful inspection to find the source. Disposing of infested food products will generally control the problem. If the beetle is found in damp places controlling the moisture source and drying out the area are needed.
