Why do ants move before it rains?

1, before it rains, the humidity of the air will be higher. The long-term survival and evolution of ants make their nests underground, which makes them very sensitive to the change of air humidity. When the humidity increases, ants will feel dangerous in lower places and move to higher places? .

When ants think the dryness is too high, they know that there will be drought, and they will move to a wet place. Ants migrate from highlands to lowlands to avoid dehydration and death.

3. The highlands are often exposed to the wind and the sun, and the moisture in the soil is not suitable for ants to settle in rainy days; The lowlands are closer to the groundwater level than the highlands, and they store water every time it rains. Relatively speaking, in drought, lowlands are wetter and wetter than uplands, which is suitable for ants to settle in dry days.
