What are the signs of flying ants swarming?

Swarms of flying ants are a sign that the weather will change and it will rain.

First of all, ants are sensitive to temperature. Secondly, they like sweets and so on. There are flying ants in dreary weather. When you are at home, you should get rid of food residue as soon as possible. When going out, pay attention to whether the doors and windows are closed. This kind of ant is generally more than 3 mm, usually 4 to 5 mm long. It has big transparent wings and can fly all the way to the tail. Its body shape is the same as that of ordinary black ants. Flying ants have the ability to reproduce and grow four winglets in rainy days. Ready to mate and reproduce, the female ant becomes the queen. Every spring and summer, in the sultry evening after rain, a large number of long-winged breeding ants suddenly fly out of their nests and fly at low altitude near buildings not far from their nests for a short time. This phenomenon is called marriage flying or group flying (grouping) flying ants, which is a kind of world public hazard with great harm, extremely widespread distribution and various varieties, mainly including Reticulitermes nigricans and domestic termites. The climate is warm and humid, which is suitable for the growth and reproduction of Reticulitermes nigricans and termites. Ant damage directly harms buildings, reservoirs, dams, agricultural and forestry crops, circuits and cables, cloth medicinal materials, cultural relics and other buildings. These winged ants are actually "getting married", just like people travel to get married. They are actually looking for a mate when they fly around. "Ants belong to neutral insects and have no harm to plants and human bodies. Generally speaking, they won't hurt people, even if they are bitten by ants occasionally, if they don't provoke them.
