3. If the storage area is not insect- tight (as is true of most closets, trunks, 

 and boxes) , vacuun the container thoroughly and spray all inside surfaces with 

 either 5-percent DDT or 0.5-percent lindane, applied from a pressurized spray 

 can. 



4. Cedar- lined chests are usually insect -tight, but all fabrics need to be insect - 

 free before storing. The cedar oil vapors destroy small larvae, but do not 

 kill larger ones. As added insurance in cedar chests, you can spray the inside 

 surfaces as suggested above or use a fumigant material. Either napthalene or 

 PDB (paradichlorobenzine) is the fumigant commonly used in moth crystals, 

 flakes, or balls. Use at least 1 pound of crystals, flakes, or balls for every 

 100 cubic feet of space. 



5. The clothing itself can be protected by treating in light amounts with DDT 

 (5 -percent oil spray or 10 -percent dust) or liberally moistening with a 

 fluoride-base fabric solution. Protection will last a year or more, unless 

 the clothes are washed or dry-cleaned. Caution: Infants clothing should be 

 washed or dry-cleaned before use . 



Keep outdoor insects out of your home by spraying the outside foundation wall of 

 your home with 2 -percent chlordane. Ants, spiders, centipedes, crickets, and other 

 insects invade homes in search of food or for shelter. You can reduce the use of 

 insecticides in the home by controlling these insect invaders before they enter. 



Buy chlordane as a liquid emulsion concentrate and dilute it with water to the 

 proper strength (1 pint of 45-percent chlordane liquid concentrate in 3 gallons 

 of water gives a 2-percent solution) . Spray the foundation from the sill to 

 the soil until the spray runs off. Also, spray 2 to 3 inches of soil next to the 

 foundation wall. Spray cracks or expansion joints, along porches and around steps, 

 also along the edges of sidewalks and driveways. In houses with crawl spaces, 

 treat the inside of the foundation wall, as well as the outside, and spray support 

 pillars. The average house requires about 3 gallons of finished spray. Do not 

 spray near wells or cisterns. Do not spray shrubbery or flowers, because the oil 

 may bum the foliage. Repeat the treatment in late summer for protection in the 

 fall. 



CAUTION: BEFORE APPLYING INSECTICIDES, READ THE LABELS CAREFULLY AND FOLLOW ALL 

 PRECAUTIONS. THIS WILL NOT ONLY INSURE PERSONAL SAFETY, BUT WILL ALSO PREVENT 

 RESIDUE HAZARDS.
