Black Beetle with white/creamy color band on their back. Larvae are brown hairy wormlike insects, casings may be found from the larvae. Larder beetles require an environment to support them 9 in 10 times it is cluster flies they are feeding on in structures. Also pets in the home or sanitation issues may create larder beetle environments. Larder Beetle jobs many times lead to cluster fly work on the same structure. After Cluster Flies leave structure (late May/June) the beetle and larvae tend to move into living and kitchen areas in search of food. Many times the control of the cluster flies is sufficient to alleviate the problem as we are taking away the environment supporting them. Larvae and beetles may be noted in upper ceiling light fixtures below attic indicating Cluster Flies in attic areas.
