Keep reading to find it out.

Is Wasp Nest Removal Necessary?

The answer is both yes and no. 

You can leave the wasp nest alone in situations when the nest and the wasps don’t bring any risks to you.

But there are also situations when you must remove the wasp nest because the chances of getting wasp stings are too high.

It all depends on the species of wasps and where the wasps build their nests.

Let’s find out first when wasp nest removal isn’t necessary.

When Can You Leave The Wasp Nest Alone?

If it’s a mud wasp nest, then leaving the wasp nest alone is OK.

Mud wasps are solitary wasps, and they’re docile. 

Having mud wasps around is positive for your yard or garden.

It’s because these wasps are pollinators. They also hunt and eat the garden pests harmful to your plants.

Mud wasps are blackish-blue, small, and have a long narrow waist. 

Their nests are mud tubes sticking on the walls. Or the nests can also look like pot-shaped mud sticking with the wall.

You can also leave the paper wasp nests alone under certain conditions

Paper wasps brownish-red wasps build their nests in the shape of inverted umbrellas.

There are downward-facing hexagonal cavities in the nest where they lay their eggs and rear their larvae.

Paper wasps also don’t bother you or try to sting you unless you disturb the nest.

Paper wasps will warn you by vigorously vibrating their wings with their faces towards you.

When the paper wasp nests are out of your reach or up there on a tree, roof eave, or tall structure, you can leave the paper wasp nest alone.

Those wasps won’t bother you.

When Is Wasp Nest Removal Necessary?

You must remove the wasp nest when the nest is at a place where you spend a considerable amount of time or it’s within your living space.

So, if there are wasp nests in places like porch, attic, basement, garage, inside wall cavities, sheds, under roof eaves, or on the ceiling, then remove the wasp nest.

When the wasp nest is small or in the development stage, you can remove the wasp nest by knocking it down with a rod or stick when there’s no wasp around.

If there are wasps inside the nest, don’t do it no matter how small the nest is. 

The best time to do it is during the early morning hours or late evening when the wasps are not in the nest.

If the wasp nest has grown big, please don’t try to remove the nest on your own.

You’ll aggravate the wasps, leading the wasps to sting you multiple times.

Immediately hire a professional pest controller to do it. 

Wasp nest close to your living or dwelling areas is dangerous.

If anyone goes close to the wasp nest, the worker wasps consider the individual a threat to their nest.

If you go too close to a wasp nest, intentionally or unintentionally, then you’ll attract the wasps

Wasps will think of you as a threat. That can make wasps sting you.

Many people believe that wasps can sting you for no reason

It’s because of the incidences of wasps stinging them out of nowhere.

In 99% of these cases, the victim has moved too close to a wasp nest. Or a wasp sat on him, and the victim reacted abruptly, which made the wasp aggressive. 

If there’s a hornet’s nest in your property, remove it by hiring a professional.

Hornet Nest

In the US, two types of hornets are fiercely aggressive – the European hornets and bald-faced hornets.

Hornets make their nests with a papery material. The shape of their nest is either spherical or conical. 

At times, the nest can also take shape to fill the gap or the cavity in the nesting place.

At times, hornet nests look like fitting perfectly between the gap of supporting parallel beams and the wooden ceiling.

Do not leave the hornet nest alone. Always hire professional help to remove it.

Is It Safe To Remove A Wasp Nest During The Winter?

Yes, it’s perfectly safe to remove a wasp nest during the winter. During the winter, the wasp nests are vacant.

The worker wasps die, and the queen wasp leaves the nest to hibernate during the winter months.

So, you’re not under any threat of a wasp sting. 

During the winter months you’ll notice lethargic wasps in your house especially when there was a nest in your home.

These wasps are either dying worker wasps or the queen wasp looking for a place to hibernate.

You can also even leave the wasp nest alone. It’s because wasps don’t occupy the old nest.

So, even in the coming spring, that nest would remain vacant.

Wasps always build a new nest starting from the spring season. 

This Is What Happens If You Leave A Wasp Nest Alone?

What Happens If You Leave A Wasp Nest

Leaving the nest alone is risky if there’s a wasp nest in places where you spend considerable time.

Over time, the wasp nest will grow, and more wasps will come out of it, and higher is the risk of wasp stings.

Getting rid of a fully developed wasp nest on your own is dangerous. Let a pro do it.

But if you notice a small wasp nest that has started to develop, you can use a wasp killer foam to destroy the nest or knock it down.

But you can leave an abandoned wasp nest alone in the winter months.

There will be no wasps in it, and there’s no chance of stings from wasps.

If the wasp nest is high up on a tree or a structure like a pole, then don’t bother removing it even during the wasp season. 

You’ll not attract the attention of the wasps.

Wasps are helpful for the ecosystem. They’re pollinators and natural pest controllers too. 

They eat the garden pests like aphids, mealworms, caterpillars, and beetles and play a role in keeping your plants safe. 

So, if the wasp nest is far away from you, then it’s OK to leave the wasp nest.

But there’s a catch.

The old nest can become a hiding place for many tiny bugs like beetles, mites, and ants.

From there, these bugs can spread into your home.

Also, the nest can absorb the moisture and spread it on the wall. That may lead to mildew or mold formation.

So, it’s always a good idea to knock down an old abandoned wasp nest in the winter months.

If You Remove A Wasp Nest, Will They Go Away?

Wasps will go away after removing the wasp nest only if you also treat the place where they’re nesting.

Removing a wasp nest is essential to rid wasps in a home or property. 

If you remove the wasp nest and don’t take the necessary actions to prevent them from re-nesting, then wasps can return to the same place to rebuild their nests.

When you remove the wasp nest, the wasps get aggravated and aggressive. They’ll sting anyone who is standing nearby.

Wasps will also leave pheromones behind. These pheromones will emit a smell that will act as a marker for the wasps to return to the same place and build their nests.

That’s why professional pest controllers also treat the nesting place after removing the nest to eliminate the smell of the pheromones.

That prevents wasps from coming back.

What’s An Average Wasp Nest Removal Cost?

Wasp nest removal forms part of the overall wasp treatment. So, there’s no singular cost of wasp removal.

The pest controller will visit your home for an inspection. There’ll also be follow-up visits after the wasp control to ensure that wasps don’t come back.

The cost depends on several things.

Some of them are the number of wasp nests in your property, the size of the nest, the species of wasps, how hard it is to reach the wasp nest, and many more factors.

On average, a budget of $500 is enough. However, high-end pest controllers can charge up to a grand or more.

Plus, you might have to shell out $30-$75 per follow-up visit

Many people negotiate a single price for the entire process, including follow-up visits.


What happens to a wasp nest when you leave it alone depends on three factors –

  1. Wasp species
  2. The season of the year
  3. The location of the wasp nest

If you leave a wasp nest alone in the wasp seasons, which are spring and summer, then the wasp nest will grow.

That’ll lead to an increase in wasps in your home and property.

In the winter months, the worker wasps die. The queen wasps leave their nests to hibernate.

This guide revealed nests of which wasp species you can leave alone and in what conditions.

We highly recommend not to remove wasp nests on your own no matter who tells you. You’ll expose yourself to the risk of venomous wasp stings.

Always hire a pest controller experienced in wasp removal to do the job.
