@termitespecialist_sg: Flying Termites are very attracted to artificial light. Hence, you can see them flying around, drawn towards the light. After the rain, flying termites come out from their nests, probably to dry their wings and mate. In a short while, some of them lose their wings, and they start to look for a new place to start their colony. If your house is near a swarm, there is no doubt that some of them might establish their nests in your surroundings, maybe even inside your house.
