Provent-a-mite and Sawyers tick spray are identical.
Although patented for different uses, they are in fact identical down to the T.
If you use Sawyers or PaM, be sure to treat the enclosure , NOT the snake.
Take the water bowl and snake out, fog the enclosure, stir up the substrate while fogging it then cover it for a few hours to let the harmful vapors dissipate.
