Larder Beetles


Larder Beetle adults feed primarily on flower pollen. Larvae feed on a wide variety of animal byproducts, including hides, woollen products, feathers, meat like bacon, and dry pet food. This species is native to Alberta and is not uncommon outdoors. The problem arises when they invade houses and the larvae start feeding on carpets, clothing and food. When adult beetles come inside in the spring, they lay their eggs on any food or animal product that is available. When appropriate egg-laying locations are not available, they will lay their eggs around and under baseboards. Flies are often a problem, especially in older houses, and it is not uncommon to have many dead flies under baseboards and in spaces between walls, especially in the spring. Larder beetle larvae will feed on these flies when there is nothing else available.
