THE BLOWFLY, large, noisy, and of shiny blue, green, or black, usually develops in carrion. It can be controlled in much the same manner as house flies, and, of course, should be. (Cornell University drawing.)

feed, whereas carpet beetles and silverfish do not spin silk. The latter two pests do most of their damage to material accessible from the floor or packed in drawers and trunks or on shelves. Clothes moths are just as likely to infest fabrics hanging up as anywhere else.

Webbing Clothes Moths

Of the three species of moths which infest fabrics the webbing clothes moth is the most generally destructive. The adult moth is only about one-fourth inch in size and pale cream-colored without spots or other markings. It flies into dark places behind furniture or runs hurriedly into folds of clothing when disturbed; it does not fly about lights. The four stages of the clothes moth are the egg, larva, pupa, and adult. The eggs are tiny, white and seldom seen. The larva is the "worm,, or feeding stage,

a small white caterpillar half an inch long or more when full grown. Wherever the worms travel, they spin silk threads in the form of tubes into which they withdraw for protection. The silken tunnels and webbing are conspicuous signs of the presence of clothes moths, as are also the tiny hard pellets of excrement left by the Worms and often assumed to be eggs. The pupa is the stage during which occurs the transformation of the ttworm" to the moth. At average summer temperatures of 70 to 80 degrees with liberal food supplies the insectis life cycle lasts 65 to 90 days. The adult moth lives only one to two weeks, long enough to lay 100 to 150 eggs. The moth does not feed because it has no mouth; its importance lies in its capacity to lay eggs. Clothes moths develop in woolen clothing; in furniture filled with hair or upholstered with woolen fabrics such as mohair; in woolen lint and ani mal hair collected in cracks of doors and

in vacuum cleaners; in hot and cold air shafts from a furnace; in tapestries, carpets and rugs; in hair brushes and feather dusters; in stuffed animals and birds and their skins and feathers; in felt hats and piano felts; and in hair or wool used in insulation and deadening felts. Cotton, linen, and silk are not used as food but may be cut through by the larvae to reach animal fibers or to provide cocoon material.

Carpet Beetles

Carpet beetles pass through the same four stages as clothes moths except that the adult is a beetle instead of a moth. Although several species of carpet beetles are destructive in the United States, only two of the most common ones will be described here, the black carpet beetle and the buffalo carpet. beetle. All are controlled by the same methods. Carpet beetles do not spin silk; but signs of their presence are the dead beetles and cast larval skins. The beetles are at ClOTHES MOTHS, with larvae ("worms") and webbing, are seen on a woolen blanket. It is the larva, a small, white caterpillar about a halfsinch when full grown, that "eats holes." Besides the holes, the silken tunnels and the webbing are conspicuous signs of the presence of these. While moths do not utilize plant fibers as food, they sometimes will cut through these materials to reach underlying animal fibres. (University of Minnesota photo.)


THE COMMON HOUSEFLY, more than being an abnoxious pest, is a carrier of disease and, accordingly, should be an avowed enemy in a continuing war. While more nuisancesome in places other than theatres, it is still a pest there, and besides being very annoying to patrons looking at the show, flies frequent other portions of the theatre with greater regularity. Toilets are a favorite hang-out for houseflies.

The black carpet beetle in its adult stage is a shiny, oval, plain black beetle. Althoughi-t varies in size, it is usually about one-eighth inch long. The adults live from two weeks to a month while they lay their fragile, white eggs, possibly over a hundred in number. The larva is brown and covered with short, stiff, brown hairs which lie flat and are directed toward the rear end of the body. It is slender and progressively smaller toward the rear, where a conspicuous tuft of long bristles is located. In this stage the skin is shed several times, the discarded skins often being found at the point of infestation when the actual insects are not to be seen. The larva, or feeding stage, requires several months to over a year to develop, depending on temperature and the type of food available.

The bud'alo carpet beetle is frequently known as the "buffalo bug," or, less appropriately, the "buffalo moth}, The adult beetle, usually smaller and proportionately broader than the black carpet beetle, is black spotted with white and has a bright red line down the center of the back. The larva is shiny brown or blackish and so covered with upright tufts of black hairs that it looks like a little black brush. It is much shorter and stouter than the larva of the black carpet beetle.

The protection of articles susceptible to clothes-moth and carpet-beetle injury involves a combination of precautions and procedures depending upon circumstances. While in frequent use, things are not liable to damage, but when put away for a month or more they should be protected. Tight boxes and garment bags which can be sealed to prevent the entry of insects will keep items in their original condition, provided the latter were clean and free from infestation when put away. Steps which may be taken to insure freedom from insects before storage are to brush thoroughly, shake vigorously, launder, dry clean, or fumigate. Cold storage facilities (at between 40 and 50 degrees) when available can be utilized to provide additional insurance against insect damage. The temperatures are not low enough to kill the insects but suffi CATALOGaI9h5
