AMMONIA AND HONEY BEES.
A proposed indoor wintering facility wants to use the cooling
capacity of an existing cold storage freezer that uses ammonia
for cooling.  Evidently small leaks in valves and fittings are
common.  Does anyone has information about the effect of ammonia
on honey bees/bee colonies?  Thanks!
