In the wintertime, most wasps will seek shelter to protect themselves from the cold temperatures. Wasps will hide in crevices and cracks on the outside of buildings and homes, as well as under rocks, logs, and tree bark.
Wasps may also build nests in attics and wall voids of buildings. Some wasps, such as yellow jackets, will also try to enter homes through cracks and crevices, so it’s important to seal any such openings in order to keep wasps from entering.
In the winter, wasps form large clusters, often consisting of several thousands of individuals. The larger cluster provides a significant amount of insulation and heat as the wasps share body heat with one another.
Wasps are also able to reduce their metabolism in order to conserve energy until warmer temperatures return.

Do wasps live in their nest over winter?
In short, the answer is yes! While individual wasps won’t survive over the winter, the colony will. In late summer and early autumn, the queen will lay eggs that develop into a hardy form of wasp – often referred to as the ‘winter wasp’.
These winter wasps will overwinter in the nest and when the spring comes they will become the first generation of reproducing wasps, forming a new colony which will grow over the warmer months. The queen is able to produce enough of these winter wasps to keep the colony going over the winter and into the warmer months ahead.
It is a remarkable cycle which helps ensure the survival of these colonies.
What happens to a wasp nest during winter?
When the weather begins to cool and winter starts to arrive, wasps living in a nest will no longer be able to survive and thrive. The wasps will enter a state of dormancy until the temperatures start to warm up again.
If the temperatures outside of the nest remain below 50°F, the wasps will die and the nest will become abandoned.
However, if the temperatures remain above 50°F, the wasp queen will remain dormant in the nest, and the nest will remain functioning. There will be no wasps tending to the nest, no egg production, and no larval development, but the nest will be preserved and will remain in a state of dormancy until the warm spring temperatures allow the wasps to come out of hibernation.
When spring arrives, the queen within the nest will emerge and begin to rebuild and repopulate her nest. She will begin to lay eggs and tend to the young larvae as they hatch, and the process of rebuilding her nest will begin anew.
Is it better to remove wasp nest in winter?
While it is possible to remove a wasp nest in the winter, it is generally not recommended to do so. This is because the nesting habits of most wasps tend to keep them inside their nests from mid-fall through winter and early spring.
During this time, the wasps are in their “dormant” state; meaning they are not active and therefore, likely to not sting. Allowing the wasp nest to remain until the warmer weather returns can help to reduce the possibility of getting stung.
Additionally, the cold weather can kill off a lot of the wasps, and the ones that don’t can hide in the ground or another source of heat. By leaving the nest, the wasps may still emerge once temperatures rise in the spring.
Therefore, it is best to wait and remove the nest until the warm weather returns. If the nest needs to be removed right away, it is important to be very cautious and contact a pest control specialist to take appropriate safety precautions.
When should you destroy a wasp nest?
The best time to destroy a wasp nest is in the late evening or early morning, when most of the wasps will be inside the nest. In addition, it is important to make sure that the nest is completely dry and free from standing water, as damp conditions can attract wasps.
It is best to wear protective clothing that covers as much of your body as possible, including gloves, long pants, a long shirt, and a hat with a veil. Avoid wearing strong perfumes or colognes when attempting to destroy a wasp nest as these can attract wasps.
A safe distance should be maintained from the nest while it is being destroyed, preferably at least 6 feet of distance or more. If you are using chemicals, it is important to take extreme care to avoid contact with the chemical.
Also, make sure to position yourself downwind from the nest, if possible, to avoid the risk of inhaling the fumes or getting stung by a wasp.
Do wasps come back to the same nest each year?
Yes, wasps do come back to the same nest each year. Wasps are social creatures, so they have a tendency to populate the same nesting site year after year. Some wasps may stay in the same nest for multiple years, while others may migrate to another nesting site each season.
Wasps take landscaping and environmental factors into consideration when selecting a nesting site, so the same site may be reused if conditions are suitable. Wasps are very territorial, so they will quickly return to a nest they feel is theirs.
Wasps also have a strong memory, meaning they can remember where they built their nest in previous years. Additionally, wasps often fly in loops starting and ending in the same spot which is usually their nest.
Is it OK to leave a wasps nest?
Generally speaking, it is not recommended to leave a wasps nest alone. Wasps can be very threatening and dangerous to humans, particularly when they are disturbed or feel threatened. It is best to call a pest professional to help remove the nest, especially if it is located in a high traffic area of your home.
The pest control technician can assess the situation and decide what the best course of action should be. If the nest is located away from the house and will not be disturbed, then it might be possible to leave it alone.
However, if the nest is located near people, pets, children, or buildings, it is recommended to contact a pest professional to take action.
At what temperature do wasps become inactive?
Wasps generally become inactive once the temperature dips below 43-45°F (6-7°C). This threshold can vary between species, however, with some species becoming inactive at temperatures as low as 39°F (4°C).
As temperatures rise, wasps will become more active and some species, like the European Paper Wasp, can remain active even in temperatures close to 100°F (38°C).
Wasps hibernate in colder climates and become inactive in the winter. In these climates, they may become inactive at temperatures as low as 32°F (0°C). Even in temperate climates, wasps are active only during the warmer months of the year, and during shorter periods of time.
In general, once the temperature outside drops to a certain point, wasps become inactive and seek shelter, entering a state of diapause until the temperature rises again.
What temperature kills wasps?
The exact temperature at which wasps will die varies depending on the species, however most wasps will die if exposed to temperatures between 95°F (35°C) and 112°F (44°C). When exposed to these temperatures, wasps will struggle to function and eventually die.
As the temperature increases, the wasps will become increasingly sluggish, which makes them more susceptible to existing pest control methods. For example, wasps may become easier to swat if they are exposed to higher temperatures.
Additionally, applying a concentrated heat source to a nest can also kill wasps. If the temperature inside the nest reaches 99°F (37°C), the wasps inside will usually die within one or two days.
How many years does a wasp nest last?
The lifespan of a wasp nest depends on the species, but most will last only one year. Wasps will build a nest in the spring and lay eggs, and then the nest is usually abandoned once the young have grown, usually in late summer or fall.
Paper wasps tend to rebuild nests each year, but most other types of wasps will find a new nesting spot or may even abandon the nesting altogether. Wasp larvae overwinter and adult wasps will emerge in the spring.
If a wasp nest is left undisturbed and the wasps not disturbed, it can last for multiple years but this is quite rare and most people will want to remove them when they find an abandoned nest.
Do yellow jacket wasps die in the winter?
Yes, yellow jacket wasps die in the winter. Yellow jacket wasps are considered to be annual insects, meaning that they die at the end of the season. Each year, a new generation of queen wasps emerge from hibernation and begin to build their nests for the upcoming season.
However, at the end of the year, these new populations die off, leaving no surviving overwintering yellow jacket wasps. During the winter, cold temperatures and lack of food sources prevent these wasps from surviving.
Additionally, queen wasps often seek protected environments, such as the insides of logs, trees, or buildings, to help protect them from the winter elements. While they will survive the winter, most existing populations will die off when the cold temperatures hit in late fall and winter.
How cold does it have to be for yellow jackets to die?
Yellow jackets usually enter a state of dormancy below 40°F. This type of inactivity is known as hibernation, and in some cases, colder temperatures can cause yellow jackets to die. Hibernation occurs when temperatures reach about 57°F for multiple days in a row.
In their inactive state, yellow jackets become increasingly sensitive to temperatures. A few nights of temperatures reaching even into the mid 30s can cause the more fragile specimens to die. In some cases, yellow jackets don’t need to be exposed to temperature below freezing for them to die.
Freezing temperatures can kill yellow jackets though and temperatures of 28°F and below can cause them to perish.
Winter season and cold temperatures in general can cause natural die-offs in yellow Jacket populations. Complete die-offs of yellow Jacket colonies won’t occur until temperatures stay below freezing point for extended periods of time, though.
Usually, that means temperatures staying in the mid to low 20s and below on and off for multiple days in a row.
How do you get rid of yellow jacket nests in the winter?
When it comes to getting rid of yellow jacket nests in the winter, the best course of action is to wait until the cold temperatures of winter kill off the yellow jackets. When the temperatures drop and winter begins, the yellow jackets will start to die out.
This happens because the yellow jackets cannot survive for long in temperatures below 40° Fahrenheit. Once the temperatures have dropped and the yellow jackets have died off, you can safely remove the nest and dispose of it properly.
It is important to be cautious when removing yellow jacket nests, as the yellow jackets can still be alive and become aggressive if disturbed. If possible, construct a box or cage to safely dispose of the nest so you can avoid any chance of contact with the yellow jackets.
What kills yellow jackets instantly?
The most effective way to kill yellow jackets instantly is by applying an insecticide containing natural pyrethrins and the synthetic pyrethroid cypermethrin. Pyrethrins are derived from chrysanthemum flowers and are toxic to most insect species, including yellow jackets.
Natural pyrethrins, however, tend to break down quickly when exposed to light and air, so using a synthetic pyrethroid-based insecticide is more effective for killing yellow jackets instantly. Before using any insecticide, it is important to read and follow label directions carefully.
Additionally, you can use an insecticidal dust or a bee and wasp aerosol spray to kill yellow jackets quickly. Whichever method you choose, it is important to apply the insecticide on a calm day when the yellow jackets are active and target the nest where the insects live and breed.
What happens if you block the entrance to a yellow jackets nest?
If you block the entrance to a yellow jacket nest, the wasps inside may become agitated and attempt to find another way out. This could result in them attempting to sting, as yellow jackets will protect their nest when threatened.
It is best to leave the nest alone, or get professional help in removing it. Yellow jackets may be able to dig out from below the barrier, so it is necessary to make sure the barrier goes all the way down to the ground.
If you must remove the nest yourself, it is important to never stand directly in front of the nest entrance, as this will place you in the direct line of flight for the yellow jackets. It is also important to use protective clothing and equipment, as some bees and wasps can sting through fabric.
It is recommended to spray a insecticidal dust or aerosol spray directly into the entrance of the nest in the evening, when all of the yellow jackets are inside. This is generally the safest and most effective solution for dealing with yellow jackets.
