84 DDT— Killer of Killers 



in addition to being a residual spray, can also be used as a 

 rapid-knockdown, high-kill space spray. Thus, a single 

 spray can take the place of two. 



Although residual sprays are most commonly used for 

 controlling flies and other insects on the walls of homes and 

 barns, they are also very effective against bedbugs and clothes 

 moths. Three fluid ounces of a 5 % DDT-kerosene mixture 

 properly applied to a full-sized bed will keep it free from 

 bedbugs for six months. Operators of hotels and rooming 

 houses will appreciate the value of this. They also know 

 that a bedbug spray should be as free from residual odor as 

 possible so as not to advertise to the guest that the bed he is 

 to occupy was once the dwelling place of repulsive little crea- 

 tures. 



The 5 % DDT-kerosene solution is also a good mothi- 

 cide. But because kerosene takes a rather long time to evap- 

 orate, there is some advantage in using the much-more-vola- 

 tile naphtha in place of kerosene. The fire hazard is some- 

 what greater with naphtha solutions, but one should have 

 no difficulty if he follows the same rules of caution that he 

 does when treating his clothes with cleaner's naphtha. In- 

 cidentally, if your good wool suit is treated with DDT, it will 

 remain free from moths for at least several months, unless 

 the deposit is removed by dry cleaning. 



Powdered Death 



Does your dog have fleas? Or do you have lice in your 

 pants? Don't use the spray gun! The spray would kill 

 these insects all right, but there is a possibility that some of 

 the poison might be absorbed through your dog's hide or your 

 tender skin. Take a powder — literally — a DDT powder,
