That is the natural chemistry product? I think they renamed it reptile spray. It contains Butanedioic acid (Succinic acid) which is part of biochemical reactions in most animals bodies, it is non toxic. The worst effect is a mild irritation with years of repeated use. It is often found in wine.
The reptile relief (reptile spray) maybe used as per the instructions and applied directly to the snake as per the instructions.
