> Is there any scientific evidence showing that the 3/4 inch space is needed? The 3/8 inch blocks mice and is a fairly large area ( 15 X 3/8 ~= 5 square inches).
Dr. Tom Seeley, in his book Honeybee Democracy, notes that the optimal opening size for a hive is about 15 cm2. For those of us using a non-metric measurement system, that equates to about 2.33 square inches if my calculation is correct.
One might note that with a “standard” entrance reducer, the largest opening is about half the optimal opening size that Seeley mentions.
A 3/4" opening without a reducer is about 12 sq. in. while the 3/8" opening is about 6 sq. in.
