PAM is way over priced.

The active ingredient in household lice spray is .50% permethrin and thats the only ingredient that matters it is also in the same amounts. So they are the same product. I have bought PAM for 22 a can and use it but i have also bought household lice spray for 5 a can and used it the same way you use PAM and they work the same. Just remember never spray it on your snakes. Spray the paper down let it dry then place snake in tub or tank. And repeat if needed.
