What is one common way carpet beetles enter homes?

Carpet beetles commonly enter homes by hitching a ride on humans' clothing. This is particularly relevant because adult carpet beetles are attracted to various materials, including wool, fur, and other natural fibers, which are often found in clothing. When individuals wear clothing that has been exposed to carpet beetles or their larvae, the insects can easily cling to the fabric and be brought into a new environment.

Additionally, while open windows, pets, and groceries can also introduce many types of pests into a home, they are less specific ways through which carpet beetles typically gain entry. Carpet beetles tend to be more passive pests, relying on movement and the presence of natural fibers to travel rather than seeking entry routes like other insects might. Understanding the behavior and habits of carpet beetles can help in effectively preventing and managing infestations.
