The Asian wasp (velutina) elimination with drones
Methods of treatment and removal of Asian hornet nests:
At FitoStinger, we have only one goal: to eliminate the Asian hornet (Vespa velutina) nest . And to achieve this, we use all the tools at our disposal, depending on the nest's location.
Therefore, we carry out treatments of nests located at low heights, manually, and their timely removal if requested.
We also carry out pole-mounted treatments in areas where our drone cannot fly and where we cannot reach by hand. We can also remove these nests.
And finally, our drone treatments . We use our aircraft for the detection, neutralization, and now also: the removal of Asian hornet nests.
Identification of Asian hornet nests and effects of treatments:
On the other hand, when requested, we carry out search and identification work for nests . In spring and summer, they can be very covered with foliage, which makes them extremely difficult to locate with the naked eye. We perform this work using our tracking drones.
Once the nests are located, it's time for our FitoVelu drone or any of our other treatment techniques. We will precisely approach each nest and apply the product in a targeted manner, injecting it inside and eradicating all its inhabitants almost immediately. This effect will not only occur during the application phase, but the active ingredient will remain dormant for several hours inside the nest , eliminating any wasps that were outside and returned, either to defend it from attack or to spend the night.
The following day, we will be ready to remove it if requested.
Conclusions of the treatment of the Asian wasp (velutin):
In this way we will have carried out a clean, environmentally friendly job, focusing on eradicating the harmful pest without affecting other species, whether insects or other living beings.
It's advisable to treat the nests to disrupt the wasps' natural life cycle , preventing new queens from spreading and establishing new nests for the following season. Remember that up to 200 new queens can be produced in each secondary nest.
Our drone evolves day by day, improving its navigation and artificial vision system, to automatically detect nests through its cameras and various sensors and thus carry out the application autonomously.
- All our services include a treatment guarantee
- Treatments and manual withdrawals, with pole and with drone
- Issuance of treatment certificate
- Severe allergic skin reactions (edema)
- Serious allergic reactions that can trigger death from anaphylactic shock
- Predator whose diet consists mainly of bees that hunt near the hive (84% of their diet)
- Bees also die from stress, feeling continually threatened. They do not lay eggs and generate the collapse of the hive.
-
High risk for children in recreational and school areas
- Important risk of death for allergy sufferers, due to the higher concentration of poison they inoculate if they feel threatened.
- The new queens will each found new nests
- The Asian wasp can expand at an average of 100 km radius per year
- It is essential to cut the cycle with our drone treatments
- Nests difficult to find in tall trees in spring and summer. Ideal to use our search drones to locate them
What is the Asian wasp (velutin) and what effects does it produce?
The Asian hornet (Vespa velutina) is an insect belonging to the genus Hymenoptera , the same as bees. This is a very large order of insects that includes more than 120.000 species distributed worldwide.
It is a predator whose diet consists mainly of bees that it hunts near the hive . The damage is not only based on the prey it captures, but also on the stress caused to the colony, which, under continuous predation , eliminates flight activity and egg-laying, leading to the collapse of the community.

- Shredding in crops (vineyards, fruit trees, etc.)
- They feel a predilection for areas close to bodies of water (rivers, streams, streams, reservoirs ...)
- We have special drones for searching and identifying nests
- Our FitoVelu drone will carry out the treatment, injecting the agent into the nest in a localized way.
Due to its morphological characteristics, an inexperienced person may confuse it with neighboring native species, also belonging to the Vespidae family: Vespa crabro, Vespula spp., Dolichovespula spp., Polistes spp.
The Asian hornet (Vespa velutina) measures between 19 and 29 mm in length with a wingspan of between 37 and 49 mm, with the queens being the largest.
Morphology of the Asian wasp (velutina):
- Head: the front part is orange yellow, and the upper part, visible if the insect is observed from above, is black.
- Antennas: they are black at the top, while at the bottom they tend to be brown.
- Chest : Color black or close to black, very dark, like the top of the head.
- Legs: the first leg section is dark in color, and the last 5 tarsi (the sections at the end of the limbs) are yellow.
- Abdomen: The first three abdominal sections are dark brown with a reddish-yellow-yellow posterior border. The room is practically yellow with a black triangle inside. The terminal part of the abdomen is reddish brown.
- Sting: only females possess it. Located at the end of your abdomen.

- Possible death of other species if spray or mist methods are used, such as spray guns
- The queens restart their activity in February and begin to build the primary nests
- Significant economic damage in activities such as beekeeping
- Only females have a stinger
- Image damage for the councils or managers of affected areas
- The worker wasps are in charge of the maintenance, construction of the secondary nest, feeding of young and defense of the colony
- Nests are normally found in trees more than 15 m high. But they can also be built in facades, bushes or holes in the ground.
Asian wasps (velutina) queens:
The queen can measure up to 3,2 cm, and reach a year of life. In early spring, sometimes starting in February, the queen comes out of her diapause and restart its activity, starting construction of a provisional nest (primary nest). When the first workers are born, they take over the maintenance and operation of the colony (and construction of the secondary nest). From that moment on, the queen will only dedicate herself to laying eggs. At the end of the season (generally in autumn), new breeding females and males are born, and matings occur.
Only the breeding females go into diapause, and the fertilized females will be able to found a new colony and become queens.
Asian (velutina) worker wasps:
The workers are smaller, with a size that does not usually exceed 2,5 cm. Males, however, can easily reach 3 cm. The workers, in addition to tasks such as obtaining food for the young and building and expanding the nest, also protect the nest and the matriarch, acquiring the role of soldiers.
Asian wasp nests (velutina):
L
The founding queen of the colony builds a provisional nest, called a "primary or embryonic nest". This nest is from size of a tennis ball. If the situation of the provisional nest is ideal, it will serve as the basis for the construction of the final nest of the colony. However, if not, the first workers will build a new one in a more conducive area. Usually in the top of a tree (usually more than 15 m high). But they can also build them is facades of buildings in hedges, bushes or in soil cavities. These last constructions confer them as very dangerous for potential hikers that may be in the area.
The permanent nest is called a "secondary nest ." Nests are constructed from chewed wood fibers and saliva, and can reach up to one meter in height and 80 cm in diameter. The largest nests are maintained by thousands of hosts. They are typically spherical or oval in shape and have a side exit hole, unlike those of the European hornet (Vespa crabro), which have their exit at the bottom.
Asian wasp cycle (velutin):
Each large nest can contain around 2000 wasps , and by the end of the season, it can produce several hundred fertile females (potential queens). Those that survive the winter will become the founding queens , establishing new colonies the following spring . This is why it's so important to break this cycle with our treatments. Fertile females enter diapause in sheltered locations, so they leave the nests empty and won't use them the following year.
Nests built in the canopies of tall trees are difficult to see and find during spring and summer because they are hidden in the foliage. This is why our work searching for and detecting nests with our pre-inspection drones is essential , allowing us to locate them and address the problems their members cause in a given area: nuisance to the population (including stings), damage to crops (vineyards, fruit trees, etc.) , or the destruction of entire bee colonies.
Bees make up 84% of the Asian hornet's diet (mainly for feeding its larvae)
- The nests can reach a size of 1 m high by 80 cm in diameter
- They have an oval shape and the entrance is usually on one side, unlike other species
- In each nest we can find about 2000 wasps
