Beats the hell out of me. It's being banned in other countries tho. Israel recently banned it.

It really doesn't matter. It's poison. They use it rodenticides. Rat killer.

There was a truck that overturned on I-40 this past year that was hauling some. They shut the highway down and brought hazmat crews to remediate the toxic substance...... On the other hand, the roadway was very clean afterward....lol
