I probably wouldnt use it. PAM is permethrin. That Frontline stuff is something else. I wouldnt want to mix the two. If you are worried about the room, i have been told by a couple boa breeders i talk to that hanging those Hot Shot no pest stripes in the room will work but you need to circulate the air around with like a box fan or ceiling fan. And you dont want to hang it close to the snake cages. They hang them on the opposite corner and then one runs a box fan while the other person uses a ceiling fan.
But me personally, as long as you are wiping down the outside of the cages, tables, legs and anything else mites can use to gain access to the snakes for a few months, you should be ok. I personally am not a fan of using lots of chemicals around my snakes so only thing i have ever used has been PAM.
