It can happen because of different reasons. Another way is when the colony is established by winged couple, male and female ants. They swarm out of the main nest and  fertilized female then creates a new colony. It usually happen during the summer time. They don’t bite but forging inside the homes they contaminate food and can become persistent pests. The fact is they travel in large numbers. It you see the winged odorous house ant, be sure that the invasion can start soon.
