In continuing to explore the crystal structure of insecticides, the research team began studying fluorinated forms of DDT, swapping out chlorine atoms for fluorine. They prepared two solid forms of the compound—a monofluoro and a difluoro analog—and tested them on fruit flies and mosquitoes, including mosquito species that carry malaria, yellow fever, Dengue, and Zika. The solid forms of fluorinated DDT killed insects more quickly than did DDT; the difluoro analog, known as DFDT, killed mosquitoes two to four times faster.
The researchers also made a detailed analysis of the relative activities of the solid-state forms of fluorinated DDT, noting that less thermodynamically stable forms—in which the crystals liberate molecules more easily—were more effective at quickly killing insects.
In the post-war chaos, however, DFDT manufacturing came to an abrupt end. Allied military officials who interviewed Third Reich scientists dismissed the Germans' claims that DFDT was faster and less toxic to mammals than DDT, calling their studies "meager" and "inadequate" in military intelligence reports.
In his 1948 Nobel Prize address for the discovery of the insect-killing capability of DDT, Paul Müller noted that DFDT should be the insecticide of the future, given that it works more quickly than does DDT. Despite this, DFDT has largely been forgotten and was unknown to contemporary entomologists with whom the NYU researchers consulted.

So they invented a lie in order to ban it world wide.
Only in America was it being used in excess.
That was on purpose.
They didn't want the third world population growth, lest they demand the benefit of their own natural resources.
They’ve caused millions of malaria deaths.
Fast-acting insecticide.... otherwise known as nerve gas.
The Syrian embassy can provide details on applied use and dosage. /s
Actually that wouldn’t be very difficult to do there should be inexpensive small portable black light type flashlight available
--pending updates--
Nah, if there is any justice in this world, Rachel Carson won’t be rolling over in her grave because her body has been completely consumed by bugs.
Oh sure, but you won't be able to lay an eagle egg either.
I’ve spent almost 60 nights in various hotels this year. Never even given a thought to bedbugs.
DDT was responsible for the eagle egg problem in the same way that insecticides turned out to be responsible for the bee die off.
I’m sorry to say that when I read the headline (before reading the article), the first thing that popped into my head was ‘Zyklon B’.
Were you otherwise occupied?
Died you have to worry about other...multi-legged, bed-related critters?
Nothing personal, just musing about hotels.
Amazon. Many price points available. I got one for about $25 to look for leaks in my car AC.
Yea, i kind of take offense at your comments but I’ll let it slide.
I refuse to live my life paranoid.
So when somebody on this thread mentioned black lights and hotel rooms...
My apologies.
We still have one, for checking for a couple of our now-late cats’ occasional UTI’s.
And there I was, thinking they were talking about Zyklon B.
Zyklon B was originally developed to kill lice.
My first thought as well.
After 80 years, our domestic enemies would prefer we forget.
