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?

Well damn... my bad. Comment before coffee. It was DDT.

Forrest was interviewed by Bret Weinstein if you are interested (https://www.youtube.com/watch?v=L7wYUnQUESU)

It is. The polio link was suggested for DDT, which was a controversial insecticide. But it was probably bunk, as were most other concerns about DDT: https://apnews.com/article/fact-check-polio-vaccine-ddt-pest...
