I did not mention that.
The Americans were able to eradicate malaria from the Panama Canal area without even knowing DDT existed.Did you know that the French tried to create a Panama Canal before America did? They had far too many deaths... They were literally putting a cup of water beneath the beds of Malaria patients as a "deterrent".... I don't even know what they thought they were deterring.
DDT would have killed SOME of the mature mosquitoes, reducing the death toll somewhat... You want to eradicate, you kill all the mosquito larvae.
