man I feel your pain but I have 23 snakes (now) I only had 16 or so when I got the second case of mites that came in on some reptile supplies or something cause the buggers were every were in the trailer. The PAM works great and I gottt access to something stronger and done the entire trailer in it . This stuff was ment to drop flies in resturants all day long. I covered mom's fish, placed al lthe cats outside (Were I wish they stay) put the rodents outside and blocked the reptile room off and fogged the entire trailer so much we had even spiders running out from under the trailer as they died) I had protected the repiles by setting up a window fan to push air in ( which allowed it to seep under the trailer ).. I told mom be ready ot buy a new trailer casue I be setting off a case ( or 4) of roach bombs if i ever saw one .
