ciently so to chill them into inactivity and to prevent new infestation from outside. Frequently in the northern United States some moderately cool space is available for storage purposes in the building. Moth crystals (either paradichlorobenzene or naphthalene) should be sprinkled liberally in storage boxes and bags. The fumes of these chemicals will keep moths from breeding sometimes for several months if the container is fairly airtight. Dispose of worthless articles promptly because such things frequently become the sourCe of a bad general infestation.

Insects damage upholstered furnishings by injuring the cover or by feeding within the stuliing. Cover injury is usually the result of external surface feeding but it may be due- to feeding from within. Frequent and thorough brushing and vacuum cleaning not only remove clothes-moth eggs, worms, and webbing from the back and seat but also carpet beetle larvae from the cracks around the cushion. Spraying thoroughly until the surface is uniformly damp with an oil-base moth spray will kill insects in the cover. If the. spray contains 5 per cent DDT, the cover will be protected from re-infestation for several weeks or months, depending upon thoroughness of application, light conditions, and a variety of other factors. If worms and the debris from their feeding begin to sift on to the floor underneath upholstered furniture, the stuffing is probably infested. The furniture should then be fumigated, a job best done by a professional fumigator.

Most insect injury to rugs and carpets is by carpet beetles. Clothes moths generally work on rugs only in dark places under furniture that is seldom moved or in unprotected rugs rolled up in storage. Carpet beetles develop slowly and injury by them is gradual unless the insects are extremely numerous. For these reasons it is usually easy to prevent appreciable rug injury. In fact, carpet beetles are often so well controlled by the usual cleaning routine that their presence is seldom suspected. Where carpets are fastened down and not often taken up, beetle injury may become serious, the beetles being able to remain relatively undisturbed for long periods in a single place. Infested rugs may be sent to a cleaner or fumigator, but fumigation merely rids them of insects and does not prevent reinfestation immediately after the rugs are laid down again in an infested building. This is also true of fumigated furniture. Valuable rugs may be moth-proofed to prevent injury. Results depend upon the poison used and the thoroughness of application. The fabric must be Wet through or untreated spots will be left where the insects are likely to congregate. The ordinary person is not equipped to moth-proof furniture and heavy rugs. Furthermore errors are costly. An experienced and reputable firm will back up its work and insure satisfactory performance.


Termites, sometimes called Hwhite ants," are the most destructive of all wood-consuming insects. Although in l945-THEATRE


BUFFALO CARPET BEETLE and cast larval skins are shown in this picture. This insect, frequently knowu as the t'buftalo bug" or (less appropriately) "buffalo moth," is usually smaller and proportionately broader than the black carpet beetle. Because carpet beetles develop slowly, they are generally controlled by the usual cleaning routine. Where carpets are not often taken up, iniury may be serious.'

jurious sometimes as far north as New England and the North Central States, they cause more serious damage to wooden structures in the South. Practically all this damage is done by the subterranean type of termite, which nests in the ground with tunnels extending into the wooden parts of buildings sometimes long distances above ground. These insects cannot live cut off from the moisture of the soil. Their only means of travel from the soil to their sources of cellulose for food are in the tunnels which they construct. Usually termites enter a building where the wooden

structure comes in contact with the ground, for instance, by way of wooden steps, basement window frames, or lattice work. They may also enter through cracks in the foundation or basement walls, especially in dark, damp places under sheds and loading platforms. Because termites feed Within the wood they may cause considerable damage before their presence is discovered. The first indication of damage may be broken steps or a sagging floor. Because the layman often cannot be certain if termites are responsible for structural injury or failure, a reliable pest control operator who

BLACK CARPET BEETLES, with larvae and cast skins, are shown here. The control measures for both the black and the buffalo carpet beetles are the same. Where theatre carpets are concerned, the employment of competent, reliable exterminators is recommended. (University of Minnesota photograph.)
