> How did you mix the pads back in the day, Pete?
Formic acid was delivered using a natural fiber sheathing board (8” by 9.5” by .5”) impregnated with 250 ml of 65% formic acid and placed inside a 1 gallon vented plastic bag having 675 pin-sized holes per side. The fiberboard was centered on and elevated 1/2" above the top bars of the top hive body with 2 wooden blocks. A 1”-high wooden rim was added to the top of the upper hive body of each colony in the formic acid group to accommodate the fiberboard and to improve airflow.

* This was done in a University setting. I have never used raw formic acid apart from these trials. -- PB
