The Asian wasp (velutina)

The Asian wasp (velutina) elimination with drones

Treatment and withdrawal methods:

In FitoStinger there is only one Objective: Eliminate Velutin Wasp Nest (Asian). And for this we use all the tools available to us, depending on the location of the nest.

Therefore we make nest treatments that are found at low altitude, manually and the timely withdrawal if requested.

We also carry out pole treatments, in those areas where the flight of our drone is not possible, and where we do not reach by hand. We can also remove those nests.

And finally, our drone treatments. We use our aircraft for detection, neutralization and now too: the retreat from the nests Asian wasp.

Nest identification and treatment effects:

On the other hand, when requested to do so, we carry out search and identification of nests. In spring and summer they can be very covered in foliage, which makes it extremely difficult to see with the naked eye. We carry out these works with our tracking drones.

Once the nests are located, it is our turn FitoVelu drone or any of our other treatment techniques. We will precisely approach each of the nests and apply the product in a localized way, injecting it inside and eradicating practically immediately all its guests. This effect will not only occur during the application phase, but the active ingredient will remain dormant for several hours inside the nest, eliminating all possible wasps that were outside the nest and returned to it, either to try to defend it from attack or to spend the night.

The next day, we will be at the disposal of make your withdrawal if requested.

Conclusions of the treatment of the Asian wasp (velutin):

In this way we will have done a clean job, respectful with the environment, and having focused on the eradication of the harmful pest, without affecting other species, neither insects nor another living being.

The nests should be treated to avoid the normal life cycle of wasps, cutting the possibility that new queens end up expanding and generating new nests for the following season. We remember that up to 200 new queens could be generated in each secondary nest.

Our drone evolves day by day, improving its navigation and artificial vision system, to detect nests automatically through its cameras and different 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?

La Asian wasp (velutina), is an insect belonging to the genus Hymenoptera, just like bees. A very large order of insects that includes more than 120.000 species distributed around the world.

Is a predator whose diet consists mainly of bees that hunt near the hive. The damage is not just based on the prey it catches, Sino also at Stress caused in the colony that, under continuous depredation, eliminates flight activity and egg laying, leading to 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 can confuse it with the neighboring indigenous species, also belonging to the Vespidae family: Vespa crabro, Vespula spp., Dolichovespula spp., Polistes spp.

La Vespa velutina It has a length ranging from 19 to 29 mm with a wingspan of between 37 and 49 mm. Being the largest queens.

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 the early spring, sometimes starting in February, the queen leaves 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.

The Asian wasps (velutina) workers:

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):

LThe 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 final nest is called the "secondary nest". The nests are made of chewed wood fibers and saliva, and can reach a meter in height and 80 cm in diameter. The largest nests are maintained by thousands of guests. Normally the shape is spherical or oval, and they have a lateral exit hole, unlike those of the hornet (Vespa crabro), which have their exit in the lower part.

Asian wasp cycle (velutin):

In each large nest we can find about 2000 wasps, and at the end of the season it can produce several hundred fertile females (potential queens). Those that survive the winter will be the founding queens that in the following spring they will create a series of new colonies. That is why it is very important to cut this cycle with our treatments. Fertile females diapause in sheltered locations, so they will leave nests empty and not use them the following year.

Nests built in tops 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 of nest search and detection with our pre-inspection drones, to locate them and be able to solve the problems that their individuals cause in a certain area: discomfort to the population (with bites included), damage to crops (vineyards, fruit trees, etc.), or annihilation of entire bee hives.

Bees make up 84% of the diet of the velutin wasp (mainly for feeding their larvae)
