[Edit] The below comment is inaccurate. The pesticide sprayed for gypsy moths was DDT. I am leaving this comment because it should be known that this was a thing even though it is now off topic.
P̵a̵r̵a̵q̵u̵a̵t̵ DDT is also linked to the polio pandemic. It was sprayed everywhere gypsy moths were found. Great success at killing moths. Also weakened human children to to where a common disease could get into spines and cause paralysis.
Researching this kind of stuff is not for the faint of heart. Its horrible all the way down. Not recommended for the faint of heart.
>gypsy moths
The common name is "spongy moths" now, to avoid a racial epithet.
"In July 2021 the Entomological Society of America decided to remove the name "gypsy moth" from its Common Names of Insects and Related Organisms List as "hurtful to the Romani people", since gypsy is considered an ethnic slur by some Romani people." [1]

um. My uncle died of polio, and I was a medical researcher (phd) for a while.
Polio can cause paralysis just fine on its own, it doesn't need DDT or paraquat to help it.
And you are also right that widespread spraying of DDT lead to all kind of problems (killed all the birds, for one, leading to "Silent Spring"), which one reason it was banned.
another reason is the mosquitos developed resistance.
Paraquat is a herbicide, not an insecticide, so why would it be sprayed for moths? I searched for information linking moths, paraquat, and polio, but couldn't find any. Is this claim a hallucination?
