I remember the whole DDT brouhaha, the soft shelled bald eagle and falcon eggs, etc... and how it spread to a general and unreasonable fear of chemicals, and chemistry in general... (Not complaining, because I make my living mitigating "hazardous materials"... hee hee hee... Better living through chemistry...)

Yet I am also old enough to remember the distinct smell of DDT, and once, on vacation in Mazatlan, I opened a ventilation and utility access door that I thought was a cabinet, and that oh-so-familiar odor hit me like a long lost childhood friend... We also had a SEVERE hornet problem iat our place in Italy, and just happened to find an old pint can of Chlordane, when, mixed with water and hosed onto said agents of evil hovering around our back patio light not only killed them dead but continued to make that wall a "zone of death" for the bastards for at least the next year or 2... to this day, we have NOT had a return of those things, where they used to be pervasive. Better living through chemistry, indeed!

Some people still haunt estate sales, looking for the garden shed stuff that, inevitably, still have 2-4-D, Chlordane, or DDT... No one I know, of course... (Looks skyward, whistling innocently...)
