Can you tell me what kind of pesticide is hydramethylnon and is it linked to autism, as some other pesticides are suspected?

Hydramethylnon: This is very effective for cockroaches and ants. I could find only one small-sample study from california involving people living near a factory where the stuff was made. Even the people who did the study emphasized how preliminary this work was, and you know that the vast majority of such studies aren't reproducible and thus there's probably no risk. I wouldn't worry.
