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. 
Drazinon: 0.5-percent oil solu- 
tion or water emulsion. (See “Re- 
sistant Roaches,” page 6.) 
LinpDANE: 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. 
MaaTHIon: 2-percent oil solu- 
tion or water emulsion; or 4- or 5- 
percent dust. (See “Resistant 
Roaches,” page 6.) 
RONNEL: 2-percent oil solution 
or water emulsion. (See “Resistant 
Roaches,” page 6.)
