Pest Description

Carpet Beetle Behavior

Carpet beetles prefer to be outdoors, feeding from the pollen and nectar of plants. Once introduced indoors, if the conditions are optimal, they will lay eggs in vents and in dark, hidden spaces. These eggs will hatch into larvae, and these young carpet beetles love to eat fabric, including fur, feathers, silk, wool, and other woven materials. They will also eat dead insects. If an adequate food source is available, carpet beetles will quickly infest an entire building, laying more eggs in hidden places, and creating more larvae.

Problems Caused by Carpet Beetles

Carpet beetles are a problem because of their larvae, not the adult beetle form. Larvae are the culprits behind fabric damage, and they can be a serious pest. Some of the common targets for carpet beetle larvae are rugs, carpets, book bindings, fabric furniture, skins, furs, and other items protein based items. As larvae mature, they will shed their “shells.” This is a common way that an infestation is identified. Once the cycle of eggs, larvae, and adults begins, it can be difficult to stop an infestation.

Preventing Carpet Beetles

Cleanliness is the easiest solution to preventing carpet beetles. Frequent carpet vacuuming, airing out of rugs, sweeping hardwood floors, and properly storing items made of fabric can all help prevent the carpet beetle cycle. Moth-repellent can also deter carpet beetle larvae from ingesting stored fabrics.

Eliminating and Controlling Carpet Beetles

Inspection is the first and most crucial step. A skilled pest technician can help identify the source of an infestation. A strong understanding of carpet beetles and their larvae is key to eliminating and preventing further problems. After identifying the source of the infestation, an expert will be able to give advice about cleaning or disposing of certain items.

A carpet beetle infestation may also need to undergo chemical or non-chemical treatment, and it’s always best to consult a professional when treatments are being considered. At Pest Control Inc, we use a variety of different treatment techniques, and we can advise you on the best way to eliminate and prevent carpet beetles permanently.
