im not kidding. they hitch rides. proof of point is. my mites came from the lil neighbor girls clothing that came inside my house to see my snake since they have a BP as well. they handled mine and bam literally a few days later he was infested. and it wasn't from the food items or bedding because i use the same on all my snakes and they are fine. just the BP, thats in the spare room. and thats the only snake they looked at. since my other 2 snakes are in QT i didn't allow the girls to see them. and low and behold like i said they are fine.
now i cant prove that they explore. they may only hitch a ride via contact or since they are tiny maybe the climb right out of the viv.
