NIX, the blue cap - for lice and to be used for spraying bedding
I'm not gonna drop names, but I've seen first hand that the biggest names in the business use this stuff.
I am not going to tell you it's definitely AS safe as PAM, just that I've seen this thread happen enough times to tell you that the snake won't die if you use it properly, once.
Probably any brand of bedding spray with Permethrin as the active ingredient.
Again, this is use at your own risk but I have read enough accounts of it being used successfully and none of a snake death by improper use to feel it will work fine.
