After a blow ended up in the ruff off the track during the competition in Thai Chonburi, the South Korean suddenly started jumping up and down.
The reason was that she had disturbed the peace of the fire ants that went to attack.
The ant species is known to aggressively defend its nests and has a painful bite.
The 25-year-old did her best to continue playing, but was tormented by the ants when she was about to hit the ball on the third hole.
