I wouldn't use that. I'd see if I could find Provent-a-Mite locally or order some online!! Here's a link to one site - http://www.mgreptiles.com/proventmite.html

ps. Those pest stips could leave your snake with neurological damage and just aren't worth the risk when there is such a good product like Provent a Mite! You'll have to be extremely methodical about cleaning too! Good luck getting rid of them.
