...screen. Within a few minutes, flies and mosquitoes in its path were observed to stagger and collapse. In half an hour, every insect on the beach was dead. Next day, the four-mile beach area got another fog dose. By the time weekenders arrived, a few hours later, the DDT beach test was clearly a "100% success...

The contraption sprays a dry, odorless, stainless cloud of fine oil particles containing a 5% solution of DDT. The fog disappears in a few minutes, leaving a deposit of DDT crystals on everything it touches...

From the British Ministry of Agriculture last week came news of an insecticide which may be as good as famed DDT, and perhaps better.
