is familiar with this type of damage should be consulted. In areas of the South where termites are commonly destructive the manager should make perioodic inspections of the foundations of buildings (once or twice a year) for evidence of termites. Earthen tunnels on basement and foundation walls and wood weakened by tunneling near or in contact with soil are signs of these insects. Suspicious evidence should then be brought to the attention of a pest control operator. Termite damage is relatively slow and may go on for several years before extensive repairs are necessary, particularly in the northern United States. Because utermite controlii forms a considerable racket in the hands of unscrupulous persons great care must be taken to obtain reputable advice concerning these pests.

A subterranean termite colony consists of three forms or castes of adult insects: workers, soldiers, and reproductives. The workers and soldiers are Wingless and creamy-white in color, similar in shape except for the large heads and jaws of the soldiers. The reproductiVes have wings when they first become mature. These winged termites swarm out of the nest and seek new nesting locations where they shed their wings. It is the workers which tunnel in wood to perform their task of feeding the colony located in the soil.

Other pests destructive to wood are powder-post beetles and species with similar habits which lay their eggs in the pores of unfinished flooring, and other lumber stock. The mature insects emerge through exit holes a year or two later. Infestation usually takes place when the lumber is being seasoned, damage in the case of some common species being confined to the sapwood of coarse-textured hardwoods such as oak. Often by the time an infestation is discovered the damage has been done because adult

emergence holes usually constitute the first evidence of injury. The holes are round and about 1/16 inch in diameter. Sometimes, however, siftings of fine sawdust-like borings indicate the work of powder-post beetles. Treatment of dooring or other infested woodwork with a solution of 3 to 5 per cent pentachlorophenol (Dowicide G, Permasan, and the like), in fuel oil or kerosene will kill unemerged insects and prevent further infestation. This mixture can be obtained ready prepared under a number of trade names, such as Permatox A. The

TERMITE SHELTER TUBES are seen constructed up a foundation wall in a poorly ventilated, basementless area beneath a building. Termites, sometimes called "white ants," are the most destructive of all wood-consuming insects. Since it is often virtually impossible for a layman to tell whether or not termites are doing any damage, services of a reliable pest-control operator should be engaged. (U. S. Department of Agriculture, BEPQ, photo.)


insects cannot lay their eggs in wooden surfaces which have been treated with varnish or other finishing materials which fill the surface pores. If they emerge through such finished surfaces the wood must have been infested prior to finishing.



Cockroaches frequent primarily those locations in a building where warmth and moisture are available, particularly in dark places, as around leaky steam-pipe joints in the basement or in washrooms. Cockroaches may pass to and fro from favorable feeding conditions in a nearby grocery store or restaurant to favorable hiding places in the theatre. In the South, cockroaches run freely from building to building. Where more desirable food is scarce, ceckroaches will devour the starch and gums utilized for bookbindings, for sizing fabrics, for outdoor billposting and for finishing the surface of paper and cardboard.

Several kinds of cockroaches are common, the American and oriental cockroaches being large dark-colored species from 11/; to 2 inches long when full grown, the lighter Lrown German cockroach less than % inch long. All are rather flat, active insects and have long antennae. They feed at night and scurry rapidly out of sight when surprised by the sudden turning on of lights. Cockroaches often hide in crevices behind Links, water and steam pipes, and similar locations from whence they can be driven in surprisingly large numbers by forcing roach powder into those places. The most eHicient treatment for cockroaches is the thorough dusting of all hiding places with sodium fluoride, or a mixture containing both sodium iiuoride and pyrethrum. DDT has been found to be no better than sodium fluoride. Lethane A-70, new within the past two years, is being used extensively in commercial cockroach powders, but may not give as good service as either the sodium fluoride-pyrethrum mixture or 10 per cent DDT dust. Phosphorus paste is effective against the larger species of cockroaches but not against the smaller German cockroach. Borax, an old-time firemedyii for cockroaches, is of very low efficiency.

Silverfish and Fire Brats

Silverfish and fire brats are Wingless, scaly insects, their bodies tapered and bearing three bristles at the hind end. Silverfish, as suggested by the name, are like polished silver in color, feed upon glue and starch sizing in books, wallpaper, rayon, and starched goods. They hide in cracks in damp cool places and run rapidly when disturbed. Fire brats difi'er in being a mottled gray, yellow and white, and in living in hot places around steam pipes and furnaces. Control of these insects can be accomplished with DDT (lusts or sprays.
