With all possible due respect to Charles Mraz, who is
credited with inventing the fume board, fume boards are
"sooo 20th Century", as my son would say.

Even people with a pathological fear of saws and cutting
wood can now simply buy the wooden assembly for a breeze board
http://www.bee-quick.com/bee-quick/breeze.html
from Brushy Mountain Bee Farm.  They call it
a "Ventilator Fume Board".

The metal "scoop" components for a breeze board can be
purchased at any home center (Lowes, Home Depot, 84 Lumber,
Menards... just go slog through the the train-wreck of big
box stores and frypits surrounding most towns sucking the
life out of what used to be called "downtown", and you'll
find one).  Brushy Mountain does not offer the metal parts
due to their bulk and resulting shipping cost.

There are also several people messing around with computer
CPU chip fans, batteries, and (I hope!) small solar panels
to create "turbo fume boards".  I expect at least one of
these to make it into the catalogs.

The point here is that the amount of vaporization caused
by mere heat on a metal sheet does not produce the volume
of volatiles that even a slight breeze does, and it certainly
does not move or distribute the fumes within the supers anywhere
near as quickly.  Breeze boards can clear 2 mediums at a time
with ease.



In regard to "Bee-Go" and other Butyric Anhydride/Butanoic Anhydride
products, the "exemption from the requirement for a tolerance"
that allowed a human "food use" of these chemicals was revoked
by the US EPA back in 1988.  The only apparent remaining legal
use for these chemicals in agriculture would be as a insect repellent
in dry animal feeds.  The FDA certainly is not going to suddenly
create an exemption for their use in human food.

(In the interest of full disclosure, I have an occasional hand in
Fischer Alchemy, which makes "Bee-Quick".  All the profits go to the
(USA) Eastern Apicultural Society Bee Research Fund, so I don't make
a single dime from it.  I do snitch a few bottles for myself and my
father, but I call that "quality control testing".)

Here's the relevant document:

http://www.epa.gov/fedrgstr/EPA-PEST/1997/August/Day-04/p20560.htm

   "Group 1-- Risk and hazard-based priorities. EPA has placed
   into Group 1 those tolerances and exemptions associated with
   the following types of pesticides, which based on the best
   available information to date appear to pose the greatest risk
   to the public health..."

  "The remaining pesticides in Group 1 no longer have registered
  food uses, and EPA has begun the process of proposing to revoke
  the tolerances associated with these pesticides..."

  "...Butanoic anhydride..."

  "Without a tolerance or exemption, food containing pesticide
   residues is considered to be adulterated and may not be legally
   moved in interstate commerce."

So, what part of "no food use" is unclear?  :)
