I have a neighbor who is a landscaper. He was telling me the other day that he was bathed in DDT all the time in his younger years. He says mosquitos still don’t touch him, even when they’re bugging his wife. He’s in his 70’s now, healthy and still working.
He did also say DDT was very hard on the bird population, that certain types of bird numbers were decimated and it took years for some to come back. Just an anecdotal story, but interesting.
The myth about the bird eggs becoming thinner around DDT was disproved.
