--> Wasp nest at home? Check out our expert tips



Wasps are formidable insects, not only for their venomous sting but also for their tendency to build nests in places we often frequent. This article aims to guide you on how to safely get rid of a wasp nest, adhering to both current regulations and everyone’s safety. We will also discuss wasp biology, the risks associated with their presence, and preventive measures to avoid their nesting in the future.


Understanding Wasps: Who Are They?


Different Types of Wasps

In Quebec, several types of wasps can be observed, each with distinct characteristics and behaviors. Among the most common are the yellow wasp (or paper wasp), recognizable by its yellow and black stripes and often building its ball-shaped nests in trees or under eaves. There’s also the poliste wasp, longer and slimmer, which constructs open nests, often under ledges or within structures. The sand wasp, solitary in nature, digs holes in the ground to lay its eggs. Lastly, it’s essential not to confuse wasps with bumblebees, which are stockier and hairier, nor with hornets, which are larger and can be more aggressive. Although all these species play a vital role in the ecosystem, especially in controlling pest insect populations, they can become problematic when they settle too close to inhabited areas.


Characteristics of Wasp Nests

Wasp nests are typically made of chewed paper they produce by masticating wood mixed with their saliva. They can vary in shape and size, ranging from the size of a tennis ball to that of a football or even larger.


Identifying a Wasp Nest



Where Are Wasp Nests Located?

Wasps prefer sheltered locations to build their nests. Nests can be found in hollow walls, attics, sheds, under canopies, or even in the ground.


How to Recognize a Wasp Nest?

A wasp nest is generally gray or brown with a papery texture. It’s often attached to a solid structure and may have a distinctive entrance through which wasps come and go.


Risks Associated with a Wasp Nest


Risks to Human Health

A wasp sting can cause various reactions in humans, ranging from mild localized pain to a severe allergic reaction. Most people stung by a wasp experience sharp pain, redness, and swelling around the sting site. This reaction is usually mild and fades on its own within a few hours to days. A small proportion of individuals are allergic to wasp venom. These individuals might experience symptoms like widespread itching, hives, facial swelling, mouth or throat swelling, breathing difficulties, rapid heartbeat, a drop in blood pressure, and in severe cases, anaphylactic shock. An allergic reaction to wasp venom can be potentially fatal and requires immediate medical attention.


Risks to the Surrounding Ecosystem

While wasps might be seen as pests to humans, they play a crucial role in the ecosystem as predators of many harmful insects and pollinators of certain plants. However, an excessive proliferation or the introduction of non-native wasps can disrupt the ecological balance. They might outcompete other species, reduce biodiversity, affect beneficial insect populations, and even threaten certain bird, reptile, and small mammal species that rely on these insects for food.


When Should You Get Rid of a Wasp Nest?

It’s essential to remove a wasp nest when it poses a danger to nearby people or animals. Wasps can become aggressive if they feel threatened, especially near their nest. If the nest is located close to pathways, playgrounds, home entrances, or other frequently used areas, it’s advisable to have it removed. Moreover, some individuals are allergic to wasp stings, and a single sting can cause a severe, even fatal, reaction. However, if the nest is distant and doesn’t pose an immediate threat, it might be best to leave it be.


Preparing for Wasp Nest Removal



Required Safety Equipment

When considering getting rid of a wasp nest, it’s imperative to wear appropriate safety gear to protect against potential stings. This equipment should include a full-body suit, preferably made of thick material to prevent stings through the fabric. The suit’s wrists and ankles should be tight or sealed to keep wasps out. A veiled hat is also essential to protect the face and neck. Thick gloves that extend to the forearms are recommended. Safety glasses or a face shield can be added for eye protection. Lastly, sturdy high-top shoes are advised, with the suit’s legs tucked inside. Before taking any action, ensure the entire equipment fits well, and no body part is exposed.


Methods to Safely Get Rid of a Wasp Nest

Insecticide is a commonly used method to eliminate wasps. However, precautions are essential to minimize risks.

Wasp traps are another option to get rid of a wasp nest. They must be correctly installed to be effective.

The safest and most effective option is often to hire a professional exterminator accredited by AQGP. Exterminators have the experience, knowledge, and equipment necessary to safely remove a wasp nest. The cost of an exterminator to eliminate a wasp nest ranges between $150 and $350, depending on the nest’s size and accessibility.


Frequently Asked Questions About Wasps



How to Know if a Wasp Nest is Active?

An active wasp nest will typically show movement with wasps regularly entering and exiting. If you don’t observe activity for several days, the nest might be inactive.


What’s the Best Time to Remove a Wasp Nest?

The best time to remove a wasp nest is either in early spring when the queen starts establishing the colony or late autumn when the colony is less active.


How to Keep Wasps Away Without Killing Them?

Several methods can keep wasps away without killing them, such as using natural repellents (e.g., essential oils, vinegar), setting up wasp traps, or creating a more attractive habitat for them outside your living space.


Should You Always Hire a Professional to Get Rid of a Wasp Nest?

Not necessarily, but it’s usually the safest and most effective method. If the nest is small, you’re not allergic to wasp stings, and you’re comfortable using insecticides, you might try doing it yourself. However, if the nest is large, hard to access, or you’re uncomfortable with the idea, it’s better to hire a professional.


Is it Illegal to Remove a Wasp Nest?

This depends on local regulations. In some places, it might be illegal to remove a wasp nest without a professional’s intervention, especially due to regulations on insecticide use. It’s always best to check with local authorities before proceeding.


What are the Risks of Leaving a Wasp Nest at My Home?

Leaving an active wasp nest at home can pose several risks, including potentially dangerous stings, especially for allergic individuals. Wasps can also damage your home’s structure if the nest is built within a wall or another structural part.


What are the Signs of an Allergic Reaction to a Wasp Sting?

Signs of an allergic reaction to a wasp sting can include excessive swelling around the sting area, breathing difficulties, dizziness, nausea, or fainting. If you show any of these symptoms after a wasp sting, it’s crucial to seek medical attention immediately.


Do Wasps Return to an Old Nest?

No, wasps typically do not reuse an old nest. However, they might be attracted to the same location if the conditions remain favorable for building a new nest.


How Long Does It Take for a Wasp Nest to Empty After Treatment?

This can vary, but generally, most wasps will die or leave the nest within 24 hours after treatment. However, some wasps might survive for several days, so it’s best not to approach the nest for at least a week after treatment.


Is It Possible to Prevent the Formation of Wasp Nests?

While it’s challenging to entirely prevent wasp nests, certain measures can help reduce the likelihood. Regular property maintenance to eliminate potential nesting sites, using repellents, and setting up wasp traps in early spring can be effective. Ensuring that there are no easy entry points into your home, like holes or gaps in walls or roofs, can also deter wasps from building nests.
