The larder beetles come from the family of Dermestid beetles; commonly known as the skin or hide beetles. Larder Beetles are found worldwide and considered as household insects. Due to their habitat being not specific to certain sensitivities, the Larder Beetle Population thrives and infests anywhere it finds a sustainable food source.

The larva of the larder beetle is longer in contrast to the length of a fully matured adult larder beetle; which are shorter. The larva has a brown color with a bright glow of red or times black setae exterior. Both of these exteriors belong to 2 distinctive kinds of these beetles. The baby larder beetle and the black larder beetle have two curved at the back, appendages which look like a spine attached close to its rear end. The appendages in the Black Larder Beetles are weaker at the curve than the other beetles.

The adults are usually a third (1/3) of an inch in length. The reddish brown exterior turns into a fully matured dark brown color and boasts a broad yellow band across its upper body where it has the elytra. Each of the wings has three black dots placed in such a manner that they pose as the angles of a triangle. Coarse and clear yellow layer of soft hairs covers the ventral plate or the breastbone of the beetle cover.
