I was hoping as I read that you sprayed the snake, that it was something that could be sprayed on the snake..you do mean Reptile Relief?
The idea above is one that I incorporate. Buy by the bulk and spray inside the bag (divide into two bags ..garbage bag) and shake well and leave until ready to use. When I was using paper an idea that was given to me was to pre-cut and treat the paper.
Either method works well.
