Occurred on June 13, 2023 Spring Mountain, Queensland, Australiabr br : "Filmed on the afternoon of 13 June 2023, at my home in Spring Mountain. There is an ant nest directly below my letterbox. I have had issues eradicating them due to the position. A few hours after rain, the ants are all drawn to the surface and smother the inside and outside of the letterbox. Unless I intervene with ant sand or similar, it takes them at least 24 hours to disappear.
