Larder Beetle

Dear Skin is crawling,
This Larder Beetle,
Dermestes lardarius, is a common household pest that will infest stored foods in the pantry.  According to the Penn State Department of Entomology site:  “The larder beetle is a commercial pest as well as a household pest. This is a cosmopolitan species which was historically a pest of cured meats in Europe, the United States, and Canada. The use of refrigeration, the purchase of meats in small quantities, and the lack of home curing of meats, have decreased the economic importance of this insect. However, these beetles are still common in homes, museums, mills, livestock facilities, and any place that contains a suitable food source. Typically, these would include any animal by-product such as dried dog food, furs, hides, and feathers. Also, many pantry items can become infested. Another potential food source are dead insects in attic and wall voids that become trapped when they seek an overwintering site. In the fall insects such as flies, bugs, beetles and wasps, accumulate in attics and similar spaces in the home. Many of the hibernating insects die, attracting larder beetles which lay eggs on dead insects. The larvae of the larder beetle then feed on the dead insects.”

    These bugs crop up regularly in a livingroom or bedroom where a human picks at his or her skin and pieces drop on the floor or into furniture. The picking must stop to cut off their food source. Nothing else will work.
