Carpet beetles are common household pests that feed on plant and animal matter such as wool, silk, feathers and flour. Adult carpet beetles lay their eggs on a food source, such as woollen carpet. When the eggs hatch in about two weeks, the larvae begin to feed on the wool. They travel through your home behind baseboards seeking out new food sources. You will know you have a carpet beetle in your home when you find the skins they have shed. You may also notice their fecal pellets, which resemble black grains of sand. While carpet beetles are among the hardest pests to control, there are actions you can take to alleviate your problem.

Remove the sources for them to lay their eggs. Examine dark corners and along baseboards where lint, dead bugs or hair may have accumulated. Vacuum these areas frequently. If you have an item that has a bad infestation, get rid of it. Inspect your house, including your attic, for old wasp nests or spider webs. Carpet beetles may take up residence in these items. Vacuum the corners of your pantry shelves and drawers. Food crumbs tend to accumulate in these areas making a perfect breeding ground for carpet beetles.
Freeze or Heat Method
Kill a known infestation in an item by extreme cold or heat. Enclose the item in a sealed bag, pressing out as much air as possible. Place in a freezer at -7.78 degrees Celsius or below for two weeks. Alternately, you can heat the item in an oven at 48.9 degrees Celsius for at least 30 minutes. Of course, you should take into consideration the durability against cold and heat the item has before doing either of these actions.
Protecting Your Items
Protect your possessions through proper storage. Store any items that may be susceptible to carpet beetles in a tightly sealed container. Inspect the items carefully to make sure they are clean and free of pests before placing in storage. Separate the layers with paper. For added protection, moth balls can be added, provided that they are in an enclosed space away from both humans and animals. Oil found in cedar is a known eradicator to some carpet beetle larvae. Storing your items in a cedar chest may offer some protection, although some large larvae may not be killed. Place bags of cedar chips near storage areas.
