What kind of poison would this be?
We have some new friends from Argentina. They were telling me that the old house they used to live in was next to a tannery (where they process animal hides into leather). Of course, besides being stinky, this industry produces hordes of flies, so the company would spray some sort of insecticide into the air, and the flies would drop right out of the air. My friends are wondering what this insecticide would be. Of course, they are also concerned about long term health issues that exposure to this chemical might bring. Does anyone have any ideas about what chemical this might be?
