The term "Fabric Pests" is used to describe those insects which have the ability to feed on keratin, a proteinaceous constituent of wool and other animal hair. There are approximately 30 species of moth larva, 15 species of beetle larva and hundreds of species of biting lice associated with birds known or suspected to be able to digest keratin.

The economically important fabric pests are found in the two main

groups: carpet beetles and clothes moths. In both groups, it is only

the larva which causes the damage.

Although they prefer keratin -

containing substances such as wool, hair and feathers, carpet beetles

and clothes moths will also attack other fabrics such as cotton, silk,

linen and synthetics if the fabrics are contaminated with substances of

nutritional value such as urine, perspiration, beer, milk or fruit

juice. Clean processed wool cannot support the normal life cycle of the

clothes moth unless it is contaminated with certain nutritional

supplements.

Apart from carpet beetles and clothes moths, there

are many other insect species, unable to digest keratin, but still able

to cause damage by chewing through keratin-containing fabric. These

include termites, cockroaches, crickets, silverfish, psocids (book lice)

and some dermestids.

Habits of Both Fabric Pests:

The

larvae of both prefer to feed in dark, undisturbed areas such as

closets, attics, and within boxes where woolens and furs are stored for

long periods. Clothing and blankets in constant use are seldom damaged

by these pests nor are carpets that get normal traffic or are routinely

vacuumed. The edges of carpets next to walls or underneath furniture are

often attacked.

These pests may also be found in upholstered

furniture (both inside and out) and in air ducts where the larvae may be

feeding on lint, shed pet hair and other debris. Infestations may also

originate from bird or animal nests, or an animal carcass present in an

attic, chimney or wall space. Adult carpet beetles may fly from one

house to another or eggs or larvae may be transported into a home on

articles containing wool or other animal fibers.

Damage to articles may consist of irregular surface feeding or holes eaten completely through the fabric.

How to Identify the Clothes Moth:

Clothes

moths are small (about ½ inch), buff-colored moths with narrow wings

fringed with hairs. Adult clothes moths are seldom seen because they

avoid light. Adult clothes moths do not feed so they cause no injury to

fabrics. However, the adults produce eggs, which hatch into

fabric-eating larvae. In the larval stage, clothes moths are

creamy-white caterpillars up to ½ inch long.

Webbing clothes moth

larvae spin silken feeding tunnels or patches of webbing as they move

about on the surface of fabrics. They often deposit tiny fecal pellets

similar in color to the fabric.

Casemaking clothes moth larvae

enclose themselves in a portable case that they drag with them wherever

they go. Often they leave the material they developed on and can be seen

crawling slowly over walls or ceilings. This moth may travel a

considerable distance to spin a cocoon in a protected crack or along the

juncture of a wall and ceiling.

How to Identify Carpet Beetles:

There

are many different species of carpet beetles. The adults are small,

oval-shaped beetles about 1/8 inch long. The most common, the black

carpet beetle is shiny black; others are brightly colored in various

patterns of white, brown, yellow and orange.

The larvae are about

1/8 inch to ¼ inch long and densely covered with hairs or bristles. Only

the larval stage feeds on fabric and causes damage. They will also feed

on seeds, pet food, or cereal products. In nature the adults feed on

flowers outdoors. If they are seen indoors, around light fixtures and

windows, there is a larval infestation present somewhere within the

home.

Prevention:

Good cleaning is the best

prevention. Vacuum carpets thoroughly and frequently. Pay close

attention to dark, out-of-the-way places. If you have pets, clean more

often since pet hair is a good source for these pests.1200D Oxford Fabric--https://www.oxfordfabric.net/product/oxford-fabric/1200d.html
