The "dangerous chemicals" you're referring to is bed-bug spray from months ago, that happened to get on his clothes while he was changing his bed sheets. I've seen victim-blaming before, but this takes it to a whole other level. It's genuinely scary that people like you exist.

I highly doubt it was the insecticide. It is far more likely that it was some combination of the cleaning supplies used. Many household cleaners can be used in bomb making.
