Ants hibernate once the temperature drops. During extremely cold weather, ants abandon their nests and burrow underground to escape the cold. Instead of sleeping, they remain in a state of semi-activity to survive until spring arrives.
To sustain themselves over the winter, they feed off stored food reserves they’ve collected during warmer months.

How Ants Survive the Winter
Ants are ectothermic, which means their body temperature is regulated by their environment. In winter, temps dip; ants slow down their metabolism so they can survive even in freezing weather.
Nests provide crucial protection from the cold. They burrow deep underground and create chambers to store food, keeping them warm and safe in winter.
Temperature affects behavior. When it’s too hot or too cold, ants are inactive because metabolic processes don’t function properly in extreme conditions. In mild climates, some ant colonies stay active year-round.
In sweltering heat, ants enter a state known as aestivation, where metabolic processes lower and bodily functions decelerate until cooler weather arrives. This helps conserve energy when temps rise too high for normal activity to occur safely.
Ectothermic creatures display adaptive behavior depending on environmental temperature fluctuations. Ants have efficient systems that help them thrive under varying circumstances while using the least amount of energy possible year-round.
Ant Behavior in the Winter
During winter, ants store food gathered during summer and fall to survive. They also huddle together in groups to generate heat and avoid freezing temperatures.
This behavior of huddling is similar to other social insects like bees and termites. The ants only venture out from the nest when temperatures are above freezing, foraging for food. When the temperature dips back below freezing, they return to their nests for shelter.
Additionally, since the insulation of a large group exceeds that of a single ant, this behavior helps them stay warm throughout winter until temperatures rise again in the springtime.
What do Ants do During the Winter?
Winter brings cold temperatures, and a range of different strategies must be undertaken by ants to last through the cold season. These strategies include food stocking, hibernation, and self-producing antifreeze.
Food Stocking
To last through winter, ants collect and store food as much as they can when it’s still warm enough to go out. They bring grain, fruits, and honeydews into their nests and cache them away underground or in chambers. This food stock helps to provide energy throughout the winter months when they’re less mobile.
Hibernation
Some ant species will enter a state of deep sleep during winter, known as diapause or hibernation. Worker ants are most likely to hibernate, but the queen leads this process from her chamber in the nest before it goes into hibernation itself.
During this time period, ant activity is almost entirely absent, and less than 5% of the population will wake periodically for short periods until warmer conditions return.
Self-Producing Antifreeze
Certain species of ants also produce glycerol which acts as an antifreeze that circulates throughout their bodies and keeps them at an optimal temperature even if the external temperature drops far below freezing levels.
By using this self-produced antifreeze, they’re better equipped to survive harsh winters without having to spend any energy that would normally be used in a search for warmth elsewhere.
Do Ants Die During the Wintertime?
Ants can be long-lived insects. The common black garden ant can live up to four years. Other species may live decades. Most ants make it through winter, but some don’t.
The cold could be fatal for an already-injured ant or one that doesn’t return to the nest. Generally, most of the colony will survive and make it to the next season, year after year.
What’s the Coldest Place That Ants Can Live?
The coldest place where ants can live is in the far north at the mouth of the Mackenzie River. The species of ant there is L. muscorum, and it is hardy enough to survive even in colder climates. It has been discovered living at elevations as high as 3,810 meters.
The Leptothorax muscorum is usually found living in mountain meadows, shrublands, and wooded areas, and their nests are usually amongst bark, under stones, or moss. Even in these colder environments, they are able to make lives for themselves and thrive relatively well.
It must be noted that not all species of ants can survive such harsh temperatures, nor can the same species survive in colder climates elsewhere. It’s important that you research what kind of ant you have before endorsing them for certain territories or conditions – it could mean life or death for your colony!
Important Facts and Overview
Ants go through a range of amazing winter adaptation strategies. During the winter season, ants can transform their body state to enter a type of hibernation-like sleep. Some species of ants consume more food sources than usual – this helps them survive the colder temperatures.
Besides eating plenty and storing it in their nest for the winter months, ants also use their body heat to keep themselves warm, and some seek shelter from the cold under the bark of trees.
Some ants have an additional strategy going into winter: they search for food every day outside their nest or colony – because many food sources become scarce during wintertime. This tool has proven handy for some species of ants to survive through extreme weather conditions during the cold months.
To sum up, different ant species use a variety of tactics to get through winter: storing food sources, using body heat, and even transforming their bodies in order to enter a kind of hibernation state. Some even search for food outside the nest during the cold months in order to make it safely through the winter season.
