Ancient beliefs suggest that witnessing swarms of ants crawling into your house is a sign that a flood is imminent.
According to feng shui, ants nesting indoors indicates that the house is deeply eroding inside, which is a very bad phenomenon.
If a nest has many branches penetrating the foundation or walls, it can severely weaken the construction quality and damage the structure.
This structural damage not only degrades the physical foundation of the house but also destroys its original good feng shui features.
However, there is no need to worry if a drove of ants nests inside for only a short time and then leaves.
This brief intrusion is often just a temporary phenomenon that occurs naturally during the flood season or when the weather changes.
Furthermore, whether ants entering your home to build a nest is a bad thing relies heavily on the specific type of ant.
Red ants crawling into the house are regarded as a sign of good fortune and symbolize a noble person appearing to help you.
Black ants indicate that a distinguished guest is about to arrive, bringing great news and a chance to change family fortunes.
Conversely, winged ants entering the home are considered a bad omen rather than a sign of upcoming luck or positive change.
