I was on the tour visit to a Bee Farm last recently. Surprisingly, the one doing the tour talk was making this statement. The same statement triggered my interest as the Tualang honey I purchased was attracting the ants.

I bought around 3kg the honey from this farm, surprisingly the honey purchased from this farm really didn't attract any ants event when there was some honey residual at the bottle's lid.

The same observation & the reading online gave some mixed points. Perhaps the pure honey that's don't attracted ants only valid for certain species of honey bees.
