How do ants prepare for winter and where do they spend the winter?

Preparing the whole nest for the winter is a very important and crucial stage in its life. After all, it is necessary to sufficiently insulate the «roof», stock up the right amount of food, withdraw all new individuals. In addition, there are species that do not hibernate for the period of cold weather, but their activity is reduced to a minimum — the workers monitor the condition of the cells, reinforce and repair them if necessary.

How and where do ants winter?

Preparing for the winter with ants — very laborious process. The main part of the work on preparing the colony for the cold is aimed at stocking up the necessary amount of food — seeds, caterpillars, dry plants. In addition, there is a massive feeding of all remaining larvae, as well as checking the available compartments for wintering and, if necessary, digging new ones.

This is necessary in order for individuals not to freeze — a constant warm microenvironment is kept in them all the time.

All the main outlets from the colony are carefully blocked with clay, earth, and dry plants. However, during thaws, some may temporarily open for ventilation.

If during the winter period, the upper part of the nest is wetted, a special detachment drags all supplies into deeper compartments.

What do ants do in winter? Some species of ants sleep in winter, but their organs function in slow motion. The rest continue to work, but their activity drops significantly. The ant’s body can withstand temperatures up to -50 degrees. This is achieved through the accumulation of large amounts of sugary substances.

Ants spend the winter in their anthill, moving to special deep chambers. This time they do not sleep, but they reduce activity to a minimum. The process of preparing for the cold includes the creation of stocks, the withdrawal of the remaining larvae and the creation of new compartments for wintering.

Do Ants Sleep?

Do Ants Sleep

Ants never rest, or so it seems. You never see them taking a break or wandering drowsily along. Ants’ nonstop behavior might spur the questions, do ants sleep?, and if so, what are the sleep habits of ants? How much do ants sleep? A new study by researchers at the University of South Florida in St. Petersburg that was published in the Journal of Insect Behavior has shed new light on the sleeping habits of ants.

It turns out that ants do sleep, and some of them even appear to dream. Worker ants, long used as symbols of industry and efficiency, survive on the insect equivalent of hundreds of tiny naps a day as they go about their endless work. Their queens, on the other hand, routinely sleep for as much as nine hours a day.

Researcher Deby Cassill, along with coauthors Skye Brown, Devon Swick and George Yanev, conducted the first research project to answer the question “Do ants sleep?” Cassill and her associates focused on the fire ant, known to scientists as Solenopsis invicta.

Worker ants are easily replaced by others that are indistinguishable from them. Creating a new queen, on the other hand, requires a considerable commitment of time and effort on the part of the colony. Fire ant queens live for years, while the lifespan of a worker is measured in months. Cassill and her team of researchers speculated that the poor sleeping habits of the worker ants could be part of the cause of their dramatically shorter lifespans.

However, the worker ants’ habit of grabbing quick power naps when time allows helps to protect and preserve the ant colony. Refraining from long periods of sleep each day keeps worker ants ready to defend the colony and tend to its needs around the clock.

The researchers created an artificial, glass-enclosed colony in the laboratory and equipped it with cameras that tracked every move of the colony. This provided researchers with a fascinating reality show starring three queens and thirty worker ants, as well as 30 larvae.

Cassill and her team expected to find that the ants, which live beneath the ground, followed schedules that had nothing to do with the cycles of light and darkness that rule the sleeping and waking patterns of most surface-dwellers. Their hypothesis proved to be correct. They discovered that the workers followed an irregular sleeping pattern, with each individual worker napping at odd times throughout the day and night. Workers slept slightly longer than minutes each nap, but took an average of 250 of these tiny naps for a total of nearly five hours of sleep per day.

The workers did not sleep in groups, and rarely did the researchers observe more than 20 percent of the workers sleeping at one time. However, when the workload slowed, the workers took advantage of this by taking more frequent naps.

Queens, which are necessary for the survival of the colony and are difficult to replace, have very different sleep habits. Compared to the worker ants, the three queens studied in the project maintained a more regular schedule. In fact, the queens all slept at the same time, piling on top of each other like puppies in a litter and then separating when they awoke.

The queens slept about six minutes at a time, 90 times each day. The queens’ took two different types of naps. One type of nap resembled a light doze. During these dozes, the queens’ antennae remained partly raised and their mouths stayed open. A worker ant or the movement of another queen could easily awaken a queen who was merely dozing.

Some of the queen ants’ naps seemed to be much deeper. During these deeper naps, the queens’ antennae would retract and their mouths would close. Often, the queens appeared to be dreaming, exhibiting antenna movement that the researchers speculated might equate to eye movements that indicate the dream stage of sleep in mammals.

Much of sleep’s purpose is still a mystery. However, the way an ant colony is set up suggests that sleep is necessary for the health and longevity of the queens. Ironically, the very need to keep the queen well rested means that the worker ants are not allowed the same luxury.

According to Cassill, “Workers are a disposable caste whose job is to buffer the queen and her royal offspring from agents of death like exposure, starvation and predators. It is the workers who engage in the high risk behavior, thus the queen lives a long life.”

Although some ant species’ queens can live up to 45 years, fire ant queens typically live for six years and usually die of old age. Workers, on the other hand, are often killed in work-related accidents and are fortunate to survive a year before succumbing to old age.

Do Ants Hibernate in the Winter? Let’s Find Out

What To Do Ants In Winter?

If you’ve made your way here, chances are you want to know the answer to this question. So do ants hibernate?

It is a bit strange that we never see ants in the winter months right?

This is due to the fact that ants do indeed hibernate in the winter, and you’re about to find out both how and why.

So let’s dive in and find out why.

Do ants die in cold weather?

This is actually an interesting question to look at, because it really depends on the circumstances. Will an ant die if exposed to sub-zero temperatures for an extended period of time? If it’s on its own, yes, but a whole colony might not exactly die off.

Even if you had a mean streak, and placed an entire ant colony in your freezer, chances are the whole colony won’t die. Sure, some will, and while others may appear dead, this is just a state of hibernation. Not moving does not equal dead in the world of ants.

So when it comes to cold weather killing ants, it really depends on the context. An ant that’s alone will have a tough time making it through the cold, but in groups ants really are a remarkable insect. Ants will actually build nests deep underground, under rocks, or even in your home to escape the cold. These shelters, like the rock for example, will actually work as heat collectors for the species.

If ants are cold-blooded, how do they survive the winter?

The thing about ants, among other insects, is that they’re cold-blooded. All this means is that they utilize the environment to regulate the temperature within their bodies. So in the winter, it’s much harder to keep the heat in, which leads them to hibernate. They’ll stock up on fat, stop moving, and enter a state of hibernation to survive the winter. As their body temperature drops, they actually become quite sluggish in general.

So while you may not see any ants out and about once the temperature drops below 50 degrees Fahrenheit, that doesn’t mean that they’re dead. It just means they’re hibernating winter away.

How long do ants hibernate for?

The next you’ll need to know about ants, and their hibernation habits, is how long they actually hibernate for. This is due to the fact that winter lasts longer in some regions than others, so the answer can’t be the same across a place as diverse as the United States right? We have even more information on what ants do during the winter in our article Where Do Ants Live in Winter?

While ants hibernate throughout the cold months, there does seem to be a limitation on the amount of time they can do this for.

What month do ants hibernate?

In the winter months, as we’ve mentioned earlier, their cold-blooded nature will cause their bodies to become very sluggish. This will occur until the cold months are over, but the typical amount of time that ants hibernate for about 3 to 4 months on average.

Plus, in the autumn months leading up to winter, you’ll notice that there will be more ant activity around their nest. This is due to the fact that ants will actually be preparing their nest for hibernation. When it comes to hibernation limits, it really depends on how much fat the ants have stored away for the winter. Their bodies won’t be using much fuel, so that food they have stored away can really last them quite some time.

So while you may not see any ants in the winter, if you hangout by an ant hole on the first warm day of the year, you’ll start to see them poke their little heads out. Think of ants like tiny bears hibernating in a cave. They store fat, slow down, and sleep the winter away.

What do ants do during the winter months?

In the winter months, ants will mostly hibernate. As we’ve mentioned earlier, there is really not much else for ants to do in the winter. This is why nest prep is so important for ants, because without it, they could end up passing away in the winter. So while ants will most likely be hibernating in the winter months, their nests will be very active in the months leading up to the winter.

So what gets done in the nest during the winter?

During the winter, nothing really goes on in the nest. The ants will bunch up around the queen, and sleep the winter away together. It’s actually quite interesting because the queen is even inactive during the winter months. If you’re interested in ant queens, we discuss them in lots of other articles, such as this one: Are Ant Farms a Bad Idea?

This means that food runs low, no new members are born, and the nest remains quite peaceful. This is why there is so much work for the nest to do once they emerge from their hibernation.

When you think about an ant nest during the winter, there really isn’t much to think about. The nest might even appear dead at times, but trust us, they’re probably just in hibernation.

Do different species of ants do different things in the winter?

While ant species have many different traits, mindsets, and jobs, that doesn’t mean that they’re all that different when winter comes around. This is due to the fact that ants are cold-blooded as a species, which means that no matter what species of ant you’re looking at, it will definitely hibernate in the winter.

They have to do some things differently right?

Some ants may act differently than others, but this does depend on the species to an extent. In species that have one solo queen, they will gather around her and the eggs to keep them warm for the winter. This is different in species that have worker ants which are also fertile because there will be less emphasis on the queen.

Ants will essentially act the same in the winter months. Nest survival is a priority, which means ants will focus on keeping their fertile members warm.

Where do ants go in the winter?

As we’ve mentioned earlier, ants will make nests out of very different objects. This is due to the fact that each nest is set up in a strategic way to gain heat from the sun, and this is extremely important during the winter months. So let’s take a look at what types of nests ants hibernate in during the winter. Some of these might surprise you.

Under large rocks

One of the most common places you’ll find an ant nest is under a large rock. This is due to the fact that large rocks provide plenty of safety from predators in the summer months, and during the winter months, it provides an ample source of heat.

While the surface of rock might not seem hot to the touch in the winter, that doesn’t mean that it’s not holding heat. The that the rock generates is actually the sole source of life for ants with nests under rocks during the winter months.

Under tree bark

Not all ants do this, but if ants can make a home out of a tree they definitely will. Just like squirrels who hibernate in the winter, ants will quite literally do the same exact thing. Instead of being inside a carved out portion of the tree, ants will hide right underneath the bark.

This is due to the fact that the ants will use the warmth that the tree generates as a heat source to keep them warm for the winter. Plus, as you may know, a tree is the host of an array of other nutrients ants can benefit from during the winter.


When you see an anthill or an ant hole, that’s quite literally only the surface of the nest. While you may think that kicking dirt on it may snuff them out, this is hardly the case. These nests are intricate and run very deep underground. In the winter, ants that live in these nests, actually hibernate in them as well.

They’ll gather as much food as they can, and once that time comes, they’ll actually cover up the entrance hole on their own. This keeps the cold out, predators out, and makes it seem like they don’t even exist. So while you may think there are no ants around in the winter, you could have stepped over a nest today.

In your home

If ants do end up creating a nest within your home, you’re going to run into some problems. This is due to the fact that ants that create a nest in your home will actually remain active during the winter months. Therefore, instead of hibernating, the ants won’t need too due to the level of warmth your home provides.

Ants live in all different types of places, and while they may be different, they all tend to function in the same way. They’re designed to be safe, secure, and to keep the cold out.

Final Findings

Ants are much more interesting than they appear to be, and that’s due to their methods for survival. While it might seem like ants die off, as you now know, they’re really only sleeping.

Ants are not exactly the smartest insect, but the way in which they do things is truly fascinating.

Now, ants don’t automatically hibernate when it’s cold, and this is why you’ll find active ants in your home. Therefore, if you find a bunch of ants in your home during the winter, chances are there is a whole nest somewhere inside.

Where Do Ants Go in the Winter?

Where do ants go in the winter? As soon as cold weather arrives, ants seemingly disappear into thin air! And how do ants survive in the winter? Are they, like us, wrapping up their outdoor lifestyles and heading indoors or to a warmer climate? As we nestle in, stocking up on hearty soups, richer vegetables and piles of firewood, are ants also taking steps to brave the elements? The answer is yes.

Ants Prepare for Winter

Ants are masters of overwintering, or waiting out the winter season. When cold air arrives, ants’ body temperatures drop dramatically and their movements become sluggish. Ants respond by seeking out warm places, such as deep soil, under rocks or under the bark of trees.

Ants overwinter on a community level by hunkering down in clusters to maintain body heat, as they huddle protectively around the queen, sheltering their population’s lifeline. During this time, the entrance to their nests close as ant traffic slows down and ceases. When warm weather returns, the ants will become active again, opening up the entrance to venture outside. drop dramatically and their movements become sluggish. Ants respond by seeking out warm places, such as deep soil, under rocks or under the bark of trees.

Most species of ants consume large amounts of food in the autumn to put on fat, thereby allowing them to go without much food through the winter. As winter passes, ants enter a dormant stage in which they lay low, feeding off the fats, carbohydrates and proteins they stored the previous fall.

The Awakening in Spring

The first warm days of spring lull the colony out of their dormancy, and it’s back to work. Worker ants leave the nest in search of food. After they’ve located a food source, they eat and head directly back to the colony to alert others of the food find. Marking their return path, the worker ants lie down an odor trail leading from the food to the colony. The nesting ants then follow the odor back to the food; this explains the «ant trails» we see across the kitchen counter.

What Do Ants Do in the Winter?

When the weather is nice, you may notice ants busily building their mounds in your yard or crawling on trees in your neighborhood. What happens in the winter when the weather is too cold for ants? Those ants are still in your yard — or maybe they’ve found shelter in your home until things warm up again. Here’s a closer look at exactly what ants do in winter.

Ants Invite Themselves Into Your Home

Ants are cold-blooded, so they require warmth in the winter to stay alive. Your home is a fantastic shelter for this purpose. It’s temperate and provides all the food and moisture they’ll need to survive a few cold months. You may not realize you have an infestation, though, even if hundreds of ants have moved into your home. Instead, ants are likely to hide in your walls or floors. Some may stay hidden in your cabinets and only come out to search for food.

Ants come inside for warmth, but food sources — such as the plants and grains they enjoy in spring and summer — are also scarce in the winter. For this reason, they may venture into your personal space in search of food.

To discourage ants from inviting themselves in, keep your countertops clean and wipe up any crumbs that fall on the floor. Also, keep pet food sealed to avoid attracting ants.

Species You’re Most Likely to See in the Winter

Depending on where you live, these are the ant species you’re most likely to share your home with in the winter:

  • Acrobat ants
  • Argentine ants
  • Carpenter ants
  • Crazy ants
  • Dark rover ants
  • Ghost ants
  • Odorous ants
  • Pharaoh ants
  • White-footed ants

In addition to keeping your home clean, you can try a few natural recipes for repelling ants, such as applying a mix of water and vinegar or lemon to your windowsills and doorways. Also, take care to not decorate your home with plants that attract ants, such as peonies and wild parsnip. A mix of dish soap and water can kill ants on the spot, and you can purchase some diatomaceous earth to prepare a natural solution for solving your ant problem.

Other Ways Ants Survive the Winter

If your home is uninhabitable for your neighborhood ants, the insects (depending on the species) can try a few other tricks to survive:

  • Using a rock to generate heat: Some species of ant will build their colonies underneath a rock in the winter. The rock will warm up under the sun and provide sufficient heat to sustain the colony until they can emerge again in the spring.
  • Using decomposing leaves: Leaves that fall and begin decomposing provide excellent shelter for ants. Leaves also provide some warmth that these insects can use to survive the winter. To avoid inviting ants into your yard in the fall and spring, rake fallen leaves and dispose of them properly.
  • Using tree bark: Ants can also dig underneath tree bark and will hibernate there until the harsh weather passes. Try some dish soap to keep ants out of your trees.
  • Building special tunnels and mounds: To maintain their body temperature, some ants build special tunnels that retain their body heat. The insects will also close the entrances of their mounds in the winter to keep heat from escaping.
  • Digging deeper: Ants may also dig deeper into the ground and group together to generate extra heat.
  • Feasting in the autumn: When the weather starts getting colder in the fall, some species of ants start preparing for a long winter by upping their intake of fats, carbs, and proteins. Just like other animals who hibernate, these ants put on extra fat to help them keep warm while they’re dormant.
  • Clustering: Whether ants have found a good rock for shelter or have burrowed into a tree or your walls, they can generate extra warmth by clustering together. They usually center their cluster around their queen(s) to keep them warm and protect their population.

Though ants will use one of these techniques or make their way into a nearby home to hole up for the winter, they aren’t very active during this season. In fact, ants hibernate when it’s too cold for them to thrive. As soon as they’re able to consistently regulate their body temperature, they’ll arise from their winter slumber in search of new shelter and food.

Ants in Some Regions Can Thrive in the Winter

Ants change their behavior in the season simply because of the temperature and the scarcity of food. In regions where the temperature stays between 75 and 95 degrees in the winter or only dips outside of that range briefly, ants won’t have to change their behavior much — if at all.

Ants Will Emerge When the Temperature Rises

As soon as the weather is warm enough, ants will emerge from their shelter and get back to work. If you had an infestation but didn’t know it because the insects were hibernating, you may be in for an unpleasant spring.

The first wave of workers will leave the nest in search of food. If they find it outside, they’ll come back to report the news and hopefully nest closer to the source. If they find enough food in your home, however, the ants may not move from the security of your walls or floors until the environment can no longer sustain them.

What Does It Mean When Ants Are in Your House During the Winter?

Since most species of ants are dormant during the winter, you probably won’t have to deal with a pest problem (or even know you have an infestation) all season. You may see a few foragers, but you’re not likely to encounter many ants in the winter.

To avoid pest problems come spring, you need to winterize your home to make it less appealing for ants. In addition to the tips listed above for keeping these insects out of your home, perform a deep clean in the fall. Also, consider working with a local pest specialist to deal with any mounds in your yard before the ants seek the shelter of your home.
