Longer exposure will do no harm. Naphthalene is used in the same man- ner as paradichlorobenzene. It evapo- rates more slowly than PDB and there- fore infested materials require longer exposure to insure good control of insect pests. The ethylene dichloride-carbon tetra- chloride mixture is a liquid which smells like chloroform. It can be used to fumi- gate foods and household articles, but it imparts a taste to foods having a high fat or protein content; thoroughly air such products after fumigation. Use tight containers and expose products at least 24 hours at 70° F. Avoid breathing the toxic vapors. Carbon tetrachloride is a clear liquid fumigant used in the same manner as when mixed with ethylene di- chloride. Where there is hazard of im- parting an off-flavor to a product, dry ice (solid carbon dioxide) can be used. (For details see directions as given under pantry beetles on page 27.) Fumigants, which are too hazardous for the householder to use, include methyl bromide, hydrocyanic acid, and chloro- picrin. // the use of these dangerous fumigants proves necessary, the work should be done by a licensed pest control operator. Contact insecticides include nicotine pyrethrum, rotenone, organic thiocya nates, mineral oils, DDT, DDD, methoxy chlor, dieldrin, lindane, chlordane, an< malathion. They are available in con mercial preparations as concentrated liquid emulsions, solutions, wettable powders for sprays, space aerosols, aero-
