Mouth rot concern....

I just read that having a mesh top can greatly increase my BP's odds of getting mouth rot. I have never heard that before. If that is the case, should I cover the bottom of the top with saran wrap or something to that effect?

A screen lid can contribute to loss of heat and humidity - but I don't know that arid conditions thereafter can promote mouth rot. Where'd you hear that?

When I was using glass I covered the screen lid just to keep the warmth and humidity in. I left 3 of the 4 corners (bout 2" triangles on a 10gal) open on each corner. Saran wrap wasnt workign very well even when coupled with double sided tape (YES on the outside of lid lol). I found some clear ConTac "paper" which was thicker, repositionable, easier to work with, trim, moisture/mildew free (v "damp towel" technique) and inexpensive. At one point we had no fewer than 8 tanks set up that way.

some confusion there...not because of lack of heat or humidity, but because of the snake rubbing their heads on it when they are out exploring...sorry for the lack of clarification.

Ah - yeah noserub is a very valid concern - the screen texture is pretty much a cheese grater on their face.
