It sure was and it should never have been on the market. We used to spray our garden with that stuff back in the late 60's and early 70's, stated right on the label which bugs it would kill on which vegetables. It would kill just about everything including it's users evidently. We have all consumed food products that were sprayed with that stuff and even today it still exists in the soil to which it was applied.

Do you know what type of chemical they sprayed in your attic? Does it last ten years and is it safe to breathe in? If it kills termites does it have any affect on humans. Not being critical, I just want to know if it is safe.
