In ancient traditions, ants swarming into a home were seen as a warning of an approaching flood.
Feng shui also views ants nesting inside as a bad sign, hinting at internal erosion.
Deep nests with many tunnels can weaken a house’s structure and harm its energy.
However, if ants enter temporarily—especially during flood season or weather changes—it’s usually nothing to worry about.
The type of ant also matters:
Red ants are a sign of good luck. They suggest a noble person may soon help you with your problems.
Black ants mean a distinguished guest might visit, bringing great news and positive changes for the family.
Winged ants are generally considered a bad omen.
