Keith,
This happens to me all the time with my Tenodera sinensis. Yes, the ooth can/should diapause in an environment that closely matches the outside conditions (unheated garage, shed, etc). If you don.t want to disturb the ooth, you can just put the cage top in another container - like a bag. It has to be closed tight and have the ability to "breathe." You also should lightly mist the ooth every couple of weeks. Or, after about 7-10 days, you can carefully scrape the ooth off the grid using a razor. Then store the ooth upright through the winter outside.
