My girlfriend was handling our snakes about three weeks ago and noticed that they had mites. So we followed the directed steps on one of the ball python care websites to eliminate this problem. Well, this morning she again noticed that they had mites. She has more experience than I do (these two are my first balls... (there is so much wordplay in this hobby)), but even collectively we can't figure out why they're back. We've tossed a few things back and forth, like the tree, the rock, the bark. We cleaned the tree and the rock in the dishwasher and tossed the bark. I used a vinegar based cleaner (I think) and scrubbed the life out of their 75 gallon home. I guess we're just curious how to eliminate mites for good, whether it requires using a different cleaner, switching the bark (we threw the bag out last cleaning and can't remember what it was) or whatever other steps we're possibly missing. We would really appreciate any help that you all could give us and thank you greatly in advance!

Thanks ,
Brett and Stefanie
