I have mites. I have been keeping pythons for over 20 years and this is the first time I have ever had mites. To be honest I have no idea where they came from. I haven't added any snakes in a few months and my last pickup was quarantined for a month with no problems in a different room. How long is their life cycle? I walked through a local reptile rescue's display on a visit to a museum about a month ago. Didn't handle any snakes but that is about the only thing I can think of. I have already ordered Provent A Mite. Does anyone know if it can be used in tubs with gravid females? I have two females that will be laying in the next week and a few more later this month.
