herping in Texas 
Seriously though, I actually don't seal my racks...Which might sound strange...but I don't think the fumes ever really go away...and since snakes have such sensitive oraphory (sp) systems I don't want to chance it. Besides, I've never really had a problem with humidity damaging my sweater box racks...
I started using the rubbermaid boxes for hide/humidity boxes a long time ago. I got the idea to use them from using the same concept for gravid corn snakes...they will always use it as a nest box. I figured it was everything a BRB like...and they spend all their daytime hours in them. I use shallow 4" deli cups with a hole in the lid for babies...
How is that female coming along?...I'll bet your just on the edge of your seat!
