@Azuza - Yeah, that sounds a little bit crazy to me too. I'm really glad I read this article though. I had no idea this was such a common ingredient in pesticides!
I mean, I know most pesticides can be harmful to animals. That's why I try to use more natural stuff like boric acid around my apartment. I know not everyone reads warning labels though. It seems like it wouldn't be that far fetched to accidentally kill a neighbors pet with this stuff. I know in the neighborhood I grew up in, neighborhood dogs would sometimes make it into our yard.
I'm definitely going to keep a look out for this stuff if I need to buy pesticides in the future.
