Why don't ants sleep?

Answer 1

Yes they do, matter of fact.I think it depends on the species. I have White-footed Ants (Technomyrmex albipes) that come to live in my kitchen every winter and they, unlike the Argentine Ant, certainly appear to enter a dormant state very like sleep. In the morning one finds little groups of them on the countertop or, more often, under the breadboard or a plate, or in the waterjug (they have a great affinity for water) -- all still and apparently sleeping. One has to nudge them or tap sharply near them before they all come to life and run around in a bit of a panic. So yes, I would say that some ants sleep.

Answer 2

Ants do experience periods of rest, but they do not have a specific sleep cycle like humans. Ants rest in short intervals throughout the day to conserve energy, repair their bodies, and allow their colonies to function continuously. Their rest periods are brief and scattered, unlike the consolidated sleep patterns of most mammals.

Answer 3

They do sleep, while they sleep the other ants are working so it seems as if they are always awake.
