    When an insect chews a hole in your favorite sweater, chances are there will be more holes to follow. That is unless you're able to identify what type of insect made the hole.  Moths are always the first insect blamed, but crickets, cockroaches, or beetles could also be the culprits. Once you know what's causing the problem, you can get rid of them using specific pesticides or organic methods.

    Carpet Beetle

    There are three species of carpet beetles that look very similar; the only difference among them is their coloration pattern.

    • Variegated carpet beetles can have solid or splotchy coloring of black, white, brown, and yellow and are only 1/8-inch long. The larvae are oval or elongated in length and have brown or black bristles.
    • Black carpet beetles, Attagenus, have solid black bodies and brownish legs as an adult and vary in length from 3/36 to 1/8-inch. The larvae can vary from light yellow to golden to dark brown. The larvae bodies are tapered from the head to the posterior.
    • Common carpet beetles have black, white, red, and orange scales. Their larvae are reddish-brown and covered in fine hairs.

    The female beetles lay soft, white eggs in concealed places on clothing, furniture, cracks in flooring, and carpet. The eggs hatch in eight to 15 days and hatch more quickly in warmer weather.  Most carpet beetles typically produce four generations within a year. Only one generation of black beetles is produced each year.

    It is not the adult insect but the larvae that feed on fabric. They begin feeding as soon as the egg hatches. They consume natural fibers like wool, mohair, fur, and feathers and can crawl from place to place. They are most often discovered on fabric but can live in any dark crevices including air ducts, closets, and behind baseboards.

    If you see a worm-like insect with a hard shell, it is actually the larvae of the Case Bearing Clothes Moth. The larvae carry a flattened case about a 1/4 to 1/2-inch long. It is this creature that cuts holes in your clothing and other fabrics. They feed on fur, flannel, wool, soiled fabrics, and hair. The adult moths are very small and are rarely seen.

    Cockroach

    The cockroach is a serious pest: its droppings that can cause asthma, carry disease, and stain clothes. In addition, the cockroach will also damage clothes and any fabric in the home. The cockroach is attracted to perspiration and body fluid stains, food and drink spills, and laundry starch. As the cockroach eats away at these stains, it can cut holes in the fibers or weaken them so that holes appear.

    Cricket

    Crickets are not commonly thought of as an insect that eats holes in clothes, and they do not attack clean clothes. However, they find body soil, food and beverage stains, and laundry starch very attractive. The cricket will eat the remains of the stain and during its feast will often cut the threads of the fabric. This is often not discovered until after the garment is washed or worn and a sudden hole appears. Cricket excrement can stain clean clothes; if you discover an infestation you may need to rewash before wearing.

    Firebrats, relatives of the silverfish, are usually 1/4- to 1/2-inch long. The firebrat has a mottled silver and brown coat. They are wingless insects with carrot-shaped bodies and five legs. They are active at night and prefer warm spaces like attics that are over 90 degrees Fahrenheit.

    Once firebrats find a food source, they tend to stay close by. They particularly like cotton, linen, rayon, and any item that is starched. Food and beverages stains that are sugar-based are particularly attractive to the firebrat. You will recognize the damage as irregular, usually following the outlines of the stain.

    Silverfish

    Cousin to the firebrat, silverfish are wingless insects about 1/4- to 1/2-inch long with five legs. Their carrot-shaped body is completely silver in color. Silverfish are found in dark areas around 70 degrees Fahrenheit. They feed at night and stay close to food sources. Silverfish like body soil, food stains, and natural fibers like silk and cotton, as well as rayon and anything starched. As the silverfish eat it cuts irregular holes in the fiber.

    Few people consider clothing damage when thinking of termites. However, ​termites are attracted to the food source of clothing that is stained with body soil, food, or beverages. As they eat the food, they often cut into the fabric causing holes.

    Webbing Clothes Moth

    The webbing clothes moth, tineola Bisellielle is a small, pale gold moth with a wingspan of about 1/2 inch. A weak flier, it seldom leaves dark areas. Adult moths are no danger to wool, cashmere, or mohair clothes, but the larvae can be terribly detrimental as they feed and cut holes in clothes.

    The female moth lays hundreds of soft, white eggs which adhere to the fabric and hatch quickly. The larvae feed from five weeks up to two years depending on humidity, temperature, and food availability. They then spin a case and emerge as full-grown moths in 2 1/2 weeks. The cycle begins again and multiple generations can be produced within a year.
