The only challenges are providing a well sealed impervious enclosure, and ensuring that you have removed all (well, almost all) the oxygen. Note that cost comes into play, too, and the suggestions below are also fairly cost-effective. For small treatments, it is easiest to make a bag, add some oxygen absorbers, and seal (with a wide, clean seal). Keep the treatment kit at room temperature (or above, if you can), and wait an appropriate time (depending on pest and tempereature). For very large treatments, a constant flow of nitrogen or argon may be needed to compensate for leakage into the enclosure. Again, time and temperature for appropriate pest species. For most "in between" sizes, I suggest a quick partial purge with nitrogen (OK, or Argon), and the inclusion of enough oxygen absorbers to remove residual oxygen, and absorb any oxygen leaking in during treatment. That's the bare bones, and there are many "tricks of the trade" that save time, effort, and nerves, but the above rules of thumb may be useful. js Jerry Shiner Keepsafe Microclimate Systems 800 683 4696 www.keepsafe.ca <http://www.keepsafe.ca/> [email protected] Specializing in the design, procurement, and installation of environmental control systems in museums and archives. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Morgan, Amber Sent: Friday, December 21, 2012 9:32 AM To: [email protected] Subject: [pestlist] anoxic treatments

Does anyone know if there has been a good comparative study? I'm finding a good amount of literature supporting one side or another, but so far nothing that makes a direct comparison of the effectiveness of each method.
