Produced in 1960, this 2-part documentary examines the effects of widespread chemical insecticide on insects and on warm-blooded creatures including humans. Part 1 looks at the ravages of insects and the centuries-old struggle to control them. Part 2 shows experiments to find ways of controlling specific insects, while leaving harmless ones unaffected.
