The Asian Wasp (Vespa velutina), also known as the mandarin wasp, is an invasive species that has been proliferating in Portugal in recent decades. Originally from the Asian continent, this species was accidentally introduced to Europe through the transport of goods, and since then has expanded rapidly, posing a threat to biodiversity and public health.
How to Identify an Asian Hornet Nest
Asian Hornet nests are usually built in high places, such as trees, electricity poles, roofs and even abandoned buildings. They are easily identifiable by their spherical shape and the material used in their construction, which resembles chewed paper. Additionally, it is common to see a constant flow of wasps entering and leaving the nest, especially during the warmer months.

What to do if you find an Asian Hornet's Nest
If you detect an Asian Wasp nest, it is important to avoid any type of direct contact with it, as these wasps are known for their aggression when they feel threatened. The best procedure to adopt is to contact the competent authorities, such as the municipal council in your area of residence or SEPNA (GNR Nature and Environment Protection Service), so that they can safely remove the nest.
What to do in case of an Asian Hornet sting
An Asian Hornet sting can be quite painful and, in some cases, can trigger serious allergic reactions. If you are stung by a wasp of this species, it is important to act quickly. First, wash the affected area with soap and water and apply ice to reduce pain and inflammation. If you experience serious symptoms such as difficulty breathing, nausea, or significant swelling, seek medical attention immediately.
How to Get Rid of Asian Wasps
Disposal of Asian Hornet nests must be carried out safely. Never attempt to remove a nest yourself, as this may result in stings and serious injuries. Local authorities and companies specializing in pest control are qualified to carry out this task effectively and safely, ensuring the protection of both the population and the environment.
But don't worry, we have solutions that can help control Asian hornet nests. Find out more below!
The Best Products to Eliminate Asian Wasps
1. Specific Insecticides :
There are several insecticides on the market specifically formulated to control the Asian Wasp. In our store you will find a specific insecticide to eliminate wasps and their nests. The insecticide comes with detailed instructions on how to apply the product safely and effectively.
2. Capture Traps :
Capture traps are another option for controlling the Wasp and Asian Hornet population. These traps use pheromones or food attractants to attract wasps, which are then trapped inside the device. Although traps do not eliminate nests directly, they can help reduce pressure on wasp populations and protect sensitive areas.
3. Expanding Foam:
Applying expanding foam to the entrance holes of Asian Wasp nests is an effective technique for suffocating and exterminating the wasps found inside. This foam expands after application, completely filling the space and preventing wasps from escaping. Our anti-wasp insecticide also works as a foam to apply to nests.
However, it is important to use this method with caution as improper application can result in wasps being dispersed and the need for professional intervention.
4. Insecticidal Powders:
Some insecticidal powders are formulated to be applied directly to Asian Hornet nests. These products contain active ingredients that are effective in killing wasps and stopping the reproduction cycle. By applying the powder directly to the nest, it is possible to achieve quick and efficient action, minimizing risks to the environment.
In short, the presence of Asian Wasp nests in Portugal represents a growing concern, requiring a careful and coordinated approach to minimize the risks associated with this invasive species. Public awareness, together with the intervention of the competent authorities, is essential to control and mitigate the negative impacts of these wasps on our society and the local ecosystem.
