Newly constructed homes, damp areas in basements and bathrooms, and homes in rural areas are commonly affected. They remind some people of the small beetles found in flour or cereal products. Grain infesting insects do not fly under normal conditions. They will be concentrated in areas of high humidity.
Fungus beetles feed on mold or mildews and are attracted to anything that is musty smelling.
Moisture levels in new buildings will often attract these insects. Anything that will lower humidities and dry things out will help. Once cold weather sets in and kills outside beetles, and the furnace starts running, the insects will disappear. We do not suggest insecticides for control. Although flying insects sprays will kill the adults, more will migrate indoors within 24 hours.
