Has anyone considered how this affects the pheromones in the colony? Does
the Apiguard interfere with the pheromones? Do the bees start doing weird
stuff, stuff that is different and may interfere with their survival?
Also, how does ventilation affect all this? At what Apiguard concentration
level will pheromones be interfered with? Or is this like frequencies, where
Apiguard may be at one "frequency" and various Pheromones will be at other
"frequencies"?

Interesting point, Ari, but not sure that it applies in this case.
I can understand that this would be the case in which thymol crystals were
placed under the cover, where the temp varies greatly. However, I am
intentionally placing the Apiguard gel within the actual broodnest cluster,
in which the temperature is relatively constant.
The second thing to consider, is the the gel is designed to be physically
carried by the bees, along with the thymol-saturated shredded paper card,
out of the hive. We find the aromatic shredded paper within a day or so
scattered about. In the process, the bees ostensibly move the thymol, and
its fumes, throughout the colony.
A larger dose of gel in the center of the broodnest of a small colony might
simply overwhelm the bees' ability to circulate the fumes, and result in
excessive brood kill.
I'm going to have to observe more closely to see if your suggestion is
valid.
Thanks,
