Carpet bugs are tiny insects that can cause serious damage to carpets, clothes, furniture, and stored items. These pests often go unnoticed because of their small size and hidden activity. Most of the damage is done by the larval stage, which feeds on natural fibers like wool, silk, leather, and fur.
In this article, you’ll learn about 9 common types of carpet bugs, how to identify them, where they live, and how to recognize early signs of an infestation. Each section is designed to be simple and informative so you can take action to protect your home.
1.Varied Carpet Beetle
The Varied Carpet Beetle is a tiny indoor pest that can damage carpets, clothes, and stored fabrics. It often hides in dark places and goes unnoticed until it causes serious damage.
