When you bring baskets, bags, or 

 boxes of food and laundry into the 

 house, look for cockroaches that 

 may be hiding in them, and kill any 

 that you find. 



SPRAYS AND DUSTS 



Infestations can be controlled by 

 applying insecticides in sprays and 

 dusts. 



Make limited applications; do 

 not treat entire floors, walls, or ceil- 

 ings. Treat only along baseboards, 

 under cupboards, and in similar 

 places where roaches hide. Do not 

 treat surfaces used for the prepara- 

 tion of food. Do not treat storage 

 spaces that contain food. 



The following list names the most 

 commonly used insecticides, gives 

 the proper strength of each spray 

 or dust, and indicates the effective- 

 ness of each. Dusts can be bought 

 already prepared. So can most 

 sprays; others can be prepared 

 easily by following the directions 

 on the label. 



Chlordane: 2-percent oil solu- 

 tion or water emulsion; or 5-per- 

 cent dust. . . . Highly effective 

 against all cockroaches except those 

 that have developed resistance to 

 insecticides. 



Diazinon: 0.5-percent oil solu- 

 tion or water emulsion; or 1-per- 

 cent dust. (See "Resistant Roaches," 

 page 6.) 



Dieldrin: 0.5-percent oil solu- 

 tion or water emulsion; or 1-per- 

 cent dust. . . . Same effectiveness 

 as chlordane. 



Lindane : 0.5 -percent oil solution 

 or water emulsion; or 1 -percent 

 dust. . . . Effective against all 



cockroaches except those that have 

 developed resistance to insecticides. 

 Duration of effectiveness shorter 

 than that of chlordane and dieldrin. 



Malathion: 2-percent oil solu- 

 tion or water emulsion; or 4- or 5- 

 percent dust. (See "Resistant 

 Roaches," page 6.) 



Pyrethrum : Liquid or dust. . . . 

 Will require more thorough and 

 more frequent application than 

 chlordane or dieldrin.
