128 DDT— Killer of Killers

 soluble pine oil emulsion will kill the winter horse tick and 

 prevent reinfestation of the animals for a few months. And 

 our poultry raisers might like to know that a single treat-

 spray, of course, is not applied to the chickens, but to the

 a number of insect pests that make life miserable for you, and 

 have told you how DDT can alleviate your misery. Let's 

 now devote a little attention to some other insect enemies, 

 who, like the late Adolph Hitler, are strict vegetarians. We 

 told you a while back how DDT won its spurs when it saved 

 the Swiss potato crop. Let's see what else it can do for our 

 hard-working farmers and for our numerous gardeners who 

 spend the hot summer months trying to breathe some life in- 

 to a row of wilting lettuce. 



A few mosquitoes on your skin may raise a few lumps 

 and cause you to scratch — and, incidentally, to swear — but a

 causing him to lose a lot of money and, as a result, raising 

 your food bill. From a purely dollar-and-cents point of view, 

 DDT means much more to the farmer than it does to the 

 apartment-house dweller, whose entomological knowledge is 

 limited to flies, mosquitoes, ants, moths, and perhaps cock- 

 roaches. It's a little too early to get the whole story about 

 DDT for agricultural purposes, for it takes several years of
