I must admit that I am apt to take the studies and research of creditable and credible organisations like the NOAA more seriously than I do the hot air blown by some people here.
There's your problem,
Caco. Many of the organizations considered credible by the undiscerning are really not; they're generally shills for the leftist juggernaut trying to figure out new ways to redistribute wealth and/or destroy capitalism. They don't work on farms or in industry, they just read what comes from academic Meccas, regurgitate it, and think they're smart and bright, but they don't know much beyond their marching orders.
If you want a gage to determine the most credible, focus on those the left criticizes at its highest octave. There you will likely find truth, which is opposite to what is being attacked, but always assess with a skeptical eye is my advice. Everyone has an angle.
G-CPTN, I would have kept the DDT as it was really good stuff - effective and not nearly the poison it was purported to be, except for mosquitos.
I had a problem with black widow spiders when I lived on a fairly large property in Northern California. The land had old oak and almond trees, very dry in summer - the perfect habitat for black widows, who build their strong webs under every eave outside my house. The only effective control for them was Chlordane, which was banned around 1980. When the banning was announced, I went out and bought several gallons, which when diluted according to the instructions, amounted to a hundred or so shoulder sprayer fulls, assuring a long term, maybe 10 year, supply. An application of Chlordane eliminates black widows for a year and it proved to be much less toxic than a black widow spider bite.
