Key phrase: PURE HONEY.

Many years ago I tested using drops of pure honey from honeycombs of wild stinging bees which I harvested with my own hands in Kinabatangan and Ranau, Sabah. Black ants didn't eat it. They'd pause to inspect it, and then move on. I believe they're not stupid and knew that they'd get stuck to the stuff and die. But tiny red ants went kamikaze and paid the ultimate price.

Honey does absorb water vapor from the air. Over time the drops of honey did become diluted and runny. The ants then gathered around the honey and feasted on the parts of the drops which were runnier. Currently there are 2 small colonies of stingless bees locally known as kelulut on my property. I've left them alone so far, but didn't notice any ants in the immediate area.
