The above bottom board set-up is for the Organic Acid treatment with the reducer in the front. The other integral part is the special inner cover that is not shown. The two special wicks are in place with the resovoir can to the right. This same set up is used for the oil and feeding experiments with the reducer removed.
The above bottom board is the same as the other used except it has a mite detection tray in the back.
The above exploded view is from one of our Organic Acid test hives. The wick system using the acids worked extremely well in our initial test hives in August and the trial test hives in early September, when there was a lot of bees, brood and a constant 94° F temperature.
