Why are there water ants when it rains?

Giant water ants especially like to fly out of their nests in the evening before and after sultry or heavy rain. People usually think that flying ants will appear before the heavy rain comes. In fact, the activity of flying ants is not directly related to rain, but it is related to air pressure, which is generally more frequent when the air pressure is low.

Generally, giant water ants will appear in groups in April and May each year (at the turn of spring and summer) and come out in pairs to breed. Therefore, when water ants go out, they must pay attention to closing doors and windows. After termites mature, the flying radius is about 1 km. The winged adults of termites have phototaxis, so it is found that termites can fly In order to prevent them from flying indoors, we should turn on the lights as little as possible or avoid using strong light.

Citizens should ventilate the room, keep it dry, and clean up the sundries in the room at the same time, so as not to give termites room to nest. At night, especially after the rain, close the doors and windows, close the curtains, try to turn off unnecessary lights and turn them to the darkest.

If you see termites flying around outdoors at night, close the doors and windows to prevent termites from flying indoors. If these termites fly indoors, it is easy to form termite nests in citizens' homes, causing more serious harm. After the doors and windows are closed, you can turn on a light on the balcony, because the light is attractive to flying termites. Put a basin of clean water under the lamp, and termites will fall into the water and drown.
