What spacing interval is suggested for small metal fasteners used to modify honey bee hive entrances to deter hornets?
Answer
$9 ext{mm}$ to $10 ext{mm}$ intervals
Physical modification of the hive entrance using simple entrance reducers combined with small metal fasteners, like brad nails spaced at $9 ext{mm}$ to $10 ext{mm}$ intervals, allows smaller honey bees through but blocks the much larger hornets.
