Well, I just spent nearly two hours completely cleaning and PAMing all three of the tanks. When I took Nagini out to put her in her holding tub, she looked pretty clean, but I had her slide through a rag with Jurrassi-Mite just to make sure. I also applied the PAM to her cage 'twice' (once on just the bare clean tank, and again on the surface of the bedding) to be sure the darn pests weren't laying eggs under the paper away from treated areas. All three are now back home and looking happy. I'll be keeping a sharp eye on her, and making sure to treat the doorways of the apartment as well.
Thanks for all the advice! :) Now I have two hours to finish 12 journal entries for tomorrow...*sigh*
