Just an update since my initial post. I found shadow boxes and domes allowed enough outgassing of moth balls as to cause me to decide not using them. This was even after I sealed the domes, I guess the wooden bases had enough porosity to allow the gases to ventilate. After an attempt at shellac coating the bases with several coats and this still not working, I decided to go with hermetically sealed acrylic canisters of the proper size. They have been the only somewhat esthetically pleasing container that doesn't allow moth ball gases to escape. I transferred my dome bases that were already made with lep environments directly into the canisters, added both silica gel and moth flakes and sealed. I placed a humidity meter in one for seal confirmation; if the humidity didn't drop significantly and stay there, more likely than not the containment would be too leaky; so far, so good with the hermetic seals.
I ended up using my own wood. I baked several pieces for 24 hours at 225 F in the stove some months back. There has been no evidence of critter activity since and they are now part of the lep environment.
This has been quite a learning process for sure, and also somewhat costly.
