A notorious pest around the world, the Larder Beetle is an unwelcome sight in homes, museums, stores, and food plants.
The diet of the larval Larder Beetle goes well beyond items typically stored in the pantry, cupboard, or larder. The natural food sources of this species area dried, dead animal parts or plants. This means that jerky, cured meats like ham and bacon, cat and dog food as well as pet treats, and dried fish like bonito are all at risk from an attack by this beetle. Larder Beetles have even eaten through the dried, preserved animal specimens often found in museums. They are a global pest.
The small black and yellow beetle may not be noticed until damage is detected. The wide yellow band across the middle of its body is comprised of short hairs, and it sports six black dots, three on each side. Short bent antennae end with a slight bulge. Larvae are mostly dark brown with a worm-like, segmented body. Fine hairs extend from the whole body and two curved, short horns sit near the rear end. If adults are discovered in the kitchen, check all food stores for larval presence. Sealing pantry goods well helps prevent infiltration.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
