The only way to keep your colony clean and healthy is with regular thorough cleaning and fresh bedding. That being said I had great success with odors using ordinary charcoal briquets placed on top of enclosure screens and around the room. I change these out whenever clean enclosures. Charcoal is a natural absorber of odors and this has been the most effective and economical method of minimizing odors.

Hope this helps,

There is a difference between ignorance and stupidity. The ignorant can be taught, stupidity is beyond our control.
