What type of environment do black carpet beetle adults prefer?

Black carpet beetle adults prefer environments inside of homes. These insects are commonly found in indoor settings because they thrive in spaces where they can access their preferred food sources, which often include animal fibers like wool, silk, and feathers, as well as other organic materials found in household items. Typical environments include areas with carpets, rugs, upholstered furniture, or even stored clothing, making homes an ideal habitat for them.

While outdoor gardens and wooden structures may offer some potential food sources, they do not provide the concentrated and diverse materials that black carpet beetles need for reproduction and survival. Fabric warehouses could technically attract these beetles due to the abundance of materials; however, the inside of homes is where they are more frequently observed, as these environments allow them to feed and reproduce effectively in proximity to human habitats.
