When I was growing up my father had a couple of cans of insect repellent that contained DDT. He kept them in the freezer so they'd last longer. He honestly thought it was the good stuff and opposed the ban. I remember seeing them in 1975, they were Olive Drab Green cans, so probably Army Surplus.

It absolutely was the good stuff. Unfortunately it weakened the eggs of large birds resulting in near extinction, including the bald eagle.
