Answer: Bananas

The world is a big and varied place, but sometimes there just aren’t enough unique chemical compounds to go around. One particularly interesting example of an overlap between chemical compounds is found within the world of bananas and honey bees. Specifically, the chemical that gives bananas their distinct, well, banana-y smell: isoamyl acetate.

Not only does that strong smelling chemical compound lend itself to providing the scent of bananas, it’s also an alarm pheromone used by honey bees. When a honey bee attacks an intruder in the hive or otherwise uses its stinger in self-defense, a burst of isoamyl acetate is released from the stinger to alert other bees to the attack.

As the chemical is identical in both the banana and the stinger pheromone, you can (at your own risk, of course) use banana peels to antagonize honey bees.
