If large populations of carpet beetles suddenly appear in or around a structure, what other animals are likely to be present?

When large populations of carpet beetles are found in or around a structure, it is often indicative of the presence of other organic materials that are attractive to these pests. Carpet beetles are known for feeding on natural fibers, which can include items like wool, fur, and other animal-based materials.

The presence of a dead bird or rodent provides a food source for carpet beetles, as they tend to be attracted to decaying organic matter. This attraction can lead to an increase in beetle populations, as they seek out these food sources for sustenance. Dead animals can also lead to a suitable environment for carpet beetles to thrive, due to the availability of protein and fibers found in their bodies.

While live insects and spiders may be present, their connection to the carpet beetles is less direct compared to the certainty of a dead animal being an appealing resource. Habitat-defining plants and household pets are less likely to be directly linked to the sudden increase in carpet beetles. In essence, a dead bird or rodent serves as a clear food source and a catalyst for the proliferation of carpet beetles in the surrounding area.
