What happens if you leave a wasp nest? You are definitely going to find yourself in a tricky situation when you spot a wasp nesting around.

The first reaction would be to leave it alone. After all, it can be dangerous if you try to remove the nest on your own and those little rascals hurt you in return.

But, having wasps around is also not a good idea, is it? That is why it is common to ask, “wasps nest in loft, should I leave it alone or do something about it?

It is not a good idea to leave a wasp nest alone in your loft because wasps can be dangerous and sting, but use a pest control service to eliminate the nest.

What Happens If You Leave a Wasp Nest?

A wasp nest left unattended can have severe and even deadly consequences.

Trees, bushes, and other protected areas can house wasp nests. If left alone, these nests can develop and increase wasp numbers. 

It Can Make It Harder to Control

To begin, the number of wasps in a nest will normally rise over time if you leave it unattended.

The size of the nest will increase as the queen wasp keeps laying eggs that hatch into new wasps. And in no time, those nests would have hundreds or even thousands of wasps inside them.

As this is the case, abandoning a wasp nest could lead to a considerably greater population of stinging insects in the long run.

It Can Result in A Painful Encounter

Leaving the nest alone means you are never safe from being stung by those wasps. The likelihood of getting stung increases proportionally with the number of wasps in a nest.

If a wasp stings you, it can be extremely painful. Along with pain, you may also notice severe itching and swelling.

Some people are also extremely allergic to wasp stings and can have potentially fatal anaphylactic reactions. 

An Important Consideration

 The wasps in the nest may grow agitated and sting if the nest is disturbed in any way, including by accident or deliberate removal efforts. 

It Can Cause Structural Damage

Ignoring a wasp nest can eventually cause structural damage in different parts of your home, and may even hurt your business.

Some of the most common places for wasps to build their nests include:

  • Under eaves
  • In attics
  • Behind walls

The issue is that damage to the building’s framework may occur as the nest expands.

Wasps, for instance, can cause a lot of damage by chewing through drywall or insulation if their nest is inside a wall. 

It Disrupts the Natural Balance

Leaving a wasp nest might disrupt the natural balance as an added eco-hazard.

The truth is that wasps may get a bad rap, but they help with crop pollination and keep bug numbers in check. 

But, when a wasp nest is neglected, the wasps within might grow more aggressive and start attacking other insects, even good ones like honeybees.

The paper wasp is just one example of a type of wasp that can cause damage to crops because its larvae eat fruit and vegetables.

Fact: The male wasps are called drones, whereas the females are considered queen workers, and only they can sting. 

Limiting the Negative Effects of Leaving a Wasp Nest Alone

While ignoring a wasp nest is never without risk.

There are techniques to lessen the blowback:

  1. First and foremost, you should stay far away from the nest to not excite them.
  2. Avoid the wasp’s wrath by not making any sudden movements or using flashlights.
  3. It is best to wear protective clothing, such as long sleeves, slacks, and gloves.

Take Measures to Prevent Wasps Making Nests

Certain steps can go a long way in keeping wasps from making nests in your home. 

This includes doing things like:

  • Sealing up any holes or openings in the exterior of your property
  • Getting rid of things like fallen fruit or standing water
  • Keeping your trash cans closed

A professional pest control agency can help you if removing a wasp nest becomes necessary. With their specific expertise and skills, they can destroy the nest without putting you or your property at risk.  

Fact: Hanging a brown paper bag outside your house simulates a wasp nest and often dissuades them from making a nest in the region.

Do Wasps Abandon Their Nests?

Wasps are sociable insects that form vast colonies under the leadership of a queen wasp.

They are well-known for their highly organized communities, similar to those of other social insects.

However, wasp nests are temporary structures, so it is natural to wonder if the wasps ever leave them. And the truth is that they do abandon their nests. 

Reasons Why Wasps May Abandon Their Nests

Several factors might result in a wasp abandoning their nests. Some of the most frequent nest abandonment causes for wasps include: 

Environmental Changes

Things like bad weather or pollution might greatly diminish a wasp nest’s chances of survival.

Damage to the nest from things like downpours or gales might make a life for the wasps there less than ideal.

Also, if the nest is located in a flood-prone area, the wasps may leave it in search of safer ground. 

Human Interference

It has been established that human interference is a possible cause of nest abandonment.

If a homeowner tries to get rid of a wasp nest themselves and damages the nest in the process, the wasps may abandon it and build a new nest elsewhere. 

Insufficient Food

If the area around the nest does not have enough food, water, and shelter for the wasps, they will leave to find it elsewhere.

This may be the result of a combination of circumstances, such as a lack of natural resources owing to environmental variables like drought or extensive human development in the area.

Fact: Wasps usually defend their nests violently, but if another colony is more prosperous at acquiring food or territory, the other colony may elect to uproot and move. 

What Happens When Wasps Abandon Their Nests?

When wasp nests are abandoned, the colony usually breaks apart and the wasps look for new places to set up home.

Many outcomes are possible, both for the wasps and their ecosystem.

For instance: 

It Is Hard for Wasps to Relocate

Moving away from the nest can be a tense time for the wasps. The wasps will have to relocate their colony and begin the colonization process all over again.

This can be difficult if the wasps’ colony rivals others for food or territory.

It is possible that the wasps will have to divide into several smaller colonies rather than constructing one giant one

It Is Hard for Them to Survive Outside

The wasps’ nest is their safest place, therefore leaving it can be a terrifying experience for them.

While looking for a new nesting site, the wasps are susceptible to predators since they may not have the same level of protection available to them as they did in their old nest.

Hence, the wasp population may see a rise in mortality.

It Affects the Ecosystem

Abandoning a wasp nest can have both beneficial and negative results for the surrounding ecosystem.

Nests left by wasps have a positive impact on the ecosystem by providing food and shelter for other creatures.

The abandoned nest, for instance, could serve as a safe haven for other insects or small animals.

Materials used to construct the nest, like plant fibers or wood, might eventually decompose and add to the soil’s nutritional content.

Fact: Wasps do not pose a threat to human health by spreading illness through their sting, but anaphylactic shock can be life-threatening if a person is allergic to a wasp's sting. 


What happens if you leave a wasp nest? For most people, the first reaction is to try and eliminate the wasps on their own. But, others do the right thing and do not try it themselves, knowing how dangerous and violent wasps can be.

However, leaving the nest alone is not always the best thing to do, as you are always exposed to the risk of being stung.

It is always a good idea to take preventive measures, but if you already have a wasp nest in your home, let a pest control service handle things on your behalf.
