Larder Beetles (Dermestes lardarius) or moisture bugs are the most common form of household bugs found industrially and commercially in places that process flesh, meat, and raw proteins.

These beetles are used in forensics and in museums as they can clean out the flesh and the carcasses of dried dead animals and insects. They can process complex proteins efficiently. They get into cracks and crevices quickly and are found in both commercial and non-commercial spaces.

They are large and oval. They are black and have a tan-yellow band across the body. They are known to enter homes during summer and fall (hence the name 'moisture bugs'), and they leave during winters. When they gather in large groups of hundreds to thousands, they can cause insane amounts of damage. While pupating, they have a habit of boring holes in wooden structures and doors to find a safe place to pupate, like food, insulation, books.
