have you started using heat in your house at all? that always reduces the humidity considerably in my herp room even though i live in a very humid area and some of the geckos are less sticky and/or need humid hides to help with shedding since my adult enclosures are partially screen. some of the geckos are totally fine with the change but there are always a few that it seems to affect quite a bit so i have to make sure to provide more humidity for those.
