In fact, carpet beetles are very common pests found in virtually every building in the New York area and, if left untreated, can cause serious damage to carpets and clothing. Carpet beetles, as the name suggests, sometimes infest carpets. Like clothing moths, pests also feed on many other items made up of wool, leather, felt, silk, feathers, fur and leather. Such materials contain keratin, a fibrous animal protein that larvae can digest.
Cotton and synthetic fabrics, such as polyester and rayon, are rarely attacked, unless they are mixed with wool or are very dirty with food stains or body oils. Carpet beetle infestations can develop undetected and cause damage to vulnerable items. In spring, female carpet beetles lay 25 to 100 eggs, which turn into larvae within two weeks. Carpet beetle larvae can mature at a variety of humidity levels and temperatures, although they tend to avoid bright areas.
Depending on food sources and climate, larvae can take more than a year to become adults. As they develop, they lose their brown skin. Learn more about the life cycle of carpet beetles. When carpet beetles threaten products found in commercial warehouses or storage areas, a monitoring program that uses adhesive traps loaded with an appropriate pheromone (a chemical agent that attracts others of the same species) is recommended.
Infestations are usually identified by the presence of adult carpet beetles, which accumulate around windows and lights. Although carpet beetle larvae don't make cobwebs like clothing moths do, the skin they shed and fecal granules, which are about the size of a grain of salt, allow you to see where they've been feeding. Colouring and markings vary, but the furniture carpet beetle generally has a speckled appearance due to black spots that interspersed with white, dark yellow to orange scales on its wing covers. When adult carpet beetles are found indoors, they are usually seen near windows, window sills, curtains, or window panes.
Vapors accumulate to the required concentration only in an airtight container, thus killing carpet beetles. The adults and larvae of the black carpet beetle, Attagenus unicolor, are clearly different from the carpet beetles described above. They have alternate light and dark brown stripes and are distinguished from other carpet beetle larvae because they are wider at the back and narrower at the front. As they grow, carpet beetles undergo a molting process and shed several times, leaving their skin empty.
Carpet beetle infestations tend to go unnoticed for long periods of time, allowing them to cause serious damage to bedding, clothing, carpets and upholstered furniture. Vacuum, sweep and dust regularly, especially in areas where carpet beetles are most likely to infest (such as the attic). Adult carpet beetles can live both indoors and outdoors, but females prefer to lay eggs where food sources for the larvae abound. Once you see adult beetles on carpets around windows, it's usually a sign that there are eggs or larvae hiding somewhere in the house, and it's time to call a pest control professional.
When carpet beetles infest your home, there are several types of items and materials that their larvae can feed on. If left unchecked, a carpet beetle infestation can cause a significant amount of property damage. .
