What you need to know about the European hornet
Even if the hornet impresses with its size and heavy and noisy flight, this insect is social and peaceful. However, it is still best to be well protected during the destruction of the nest that it will seek to protect. the colony is created in the spring by a wintering female and disappears in the following autumn.
Difference between European hornet and Asian hornet
You must have heard about it for a few years. The Asian hornet is gaining ground in our campaigns. but how do we differentiate it from our European hornet ? In fact, by observing them more closely, there are very important differences :
|Characteristics||European hornet||Asian hornet|
|Size||Up to 4 cm
|3 cm: smaller, lighter and therefore faster than his cousin. .
|Paws||Legs entirely brown
|It is also called "yellow-legged violon." These legs are two-colored: black near the thorax and yellow on the extreme half. .
|Thorax||Her chest is bicolored: brown, red and velu
|Its Latin name ''vespula velutina nigrithorax': its thorax is black and velu. .
|Abdomen||Abdomen entirely yellow lemon, finely chopped with fine black drops.||The Asian hornet carries on the abdomen a large ring orange to its tip (when seen from the top).|
|Head||Its head is brown and red with the yellow face and more rounded than the Asian hornet.||His head is black with the orange face, more elongated.|
|During the flight||General yellow aspect. the entire abdomen is colored yellow alternated with black patterns (as for the wasps)||Dark/black aspect. lets drag his long yellow legs to the back of the body|
|Nesting site||Still nests in the dark (greniers/granges/box of rolling purple/low in a tree trunk). it is impossible to find a European hornet nest (1) in open air (2) in full light (3) and even less exposed to the weather. the nest is never visible from outside the cavity for the observer
|Niches very often in full light and in exposed situations (buildings, exterior roof advances, treetops). it can happen to her to nest in dark places especially at the beginning of the year (treak of trees but this remains rare, possibly attic but often when there is no total darkness). the nest is very often directly visible by the observer.|
|Founder appearance in spring||Founders appear very late in the year (from May 1st) sometimes at the end of April.||Founders appear very early in the year just at the end of the winter, usually in March (sometimes in late February in the south when spring is early). the Asian hornet sees its first workers appear when the first European hornet founders come out of their winter rest.|
|Night activities||The European hornet is the only social wasp capable of flying at night, so it continues its activity as if nothing was (reduced activity) in nighttime. like many night insects, workers are very often attracted to light during their night activities (tropism). to the point that some summer evenings, dozens of hornets can grow to a source of light.
|No night activity, no attractiveness for artificial light at night.
|Attacks||The European hornet does not attack in group and only stings if you come in contact by crossing its path. .
|The “Asian hornet” systematically attacks in a gust as soon as you get too close to the nest that it feels threatened and gets hard as long as you stay close. the larger the nest and the greater the security distance to be respected. at the booty and away from the nest, it is not aggressive but rather smoking. .
Our anti-moustic spirals and flying insects will allow you to keep away the hornets that would have decided to approach you or your meals outside. The smoke that consumes these spirals is composed of pyrethre. the hornets will be immediately disturbed and will pass their way: Spiral 110 mm 4-hour spiral combustion
How to eliminate hornet ?
If the nest doesn't bother you, leave him alone. it will empty its occupants in the fall and as a nest is never reused, so you can then destroy it. Be still careful because there may be some isolated specimens.
If at the beginning of the season, it is quite easy to destroy a nest with our insecticide 4j diluted to 10%, it will be much more dangerous at the end of the season. In this case, we advise you to involve firefighters or a specialized company.
For maximum efficiency, we advise you to treat hornets, either with our insecticide 4J concentrate that you'll dilute to 10% or with insecticide all pests, aerosol under pressure, allowing optimal application.
And in the field of fumigation fogger habitat Biovétol will give excellent results on this type of insect. insecticide based on plant-based assets (pyrethre + géraniol) for the background treatment of habitat. very volatile, the solution is deposited in the smallest corners where pests and insects are located. immediate and prolonged action, up to 4 months.
Otherwise, the classic hornet trap is dreadful. attracted by the food attractive that is placed in the centre of the trap, the hornets come in and can no longer emerge. They end up drowning inside and dying.
The diatomaceous earth can be very effective for the treatment of a spawning nest. the difficulty remains of being able to bring it into the heart of the nest without being attacked. certain professional appliances allow to spray this fine powder with a perch. do not advise you to introduce the earth of diatomy yourself by escalating the tree. The risks are far too important.

Frequently asked questions about the hornet
R: Unfortunately, there is no long-term natural repulsive product to remove hornets or wasps. we have a repellent based on eucalyptus citriodora (Repulsive insect habitat) but its effectiveness remains limited in time.
R: We have an anti-guêpe of aries based on essential oils but it is a small spray (50ml) and it is only a repulsive. otherwise, pistol insecticide or insecticide 4j, based on pyrethra, is very effective in eliminating them.
R: Our 4j insecticide with a concentration of 10% is very effective on hornets. as soon as the hornet is affected by the product, it flies in all directions for 10 to 15 s and falls on the ground. attacking the nest of hornets requires equipment: protective clothing and a sprayer (type garden) with extension, the nozzle will have to be adjusted rather on fine rain than on fog. It is important to treat the night when the hornets are all back and asleep. to be effective, you need to water insecticide the inside of nest. but careful with this type of treatment, it is strongly recommended to use professionals.
R: Our insecticide is very effective on freons since we have personally tried. but, given the size of these insects, it is best to dose insecticide 4d to 10.% if the hornet is properly watered, it will be ground in less than 10s. Now, our tests have always been done on isolated hornets. we strongly advise you to attack a nest without protective equipment. our product making them crazy, it fly in every direction before falling to the ground and can attack since they feel themselves assaulted. Moreover, you will never see a firefighter or a specialized company treat a nest of hornets without protection. It's a big risk. The only effective way to destroy a nest is at night, when most insects have come in and are asleep.
R: Insecticide 4j is a contact insecticide. the neurotoxic effect of pyrethra is very fast on affected insects (a few minutes). the ideal in your case is to find a time of the day or a maximum of hornets returned to the nest to act. at the quantity level, feel free to wet the whole nest, especially inside. Maximum 500 ml of the diluted product should be largely sufficient.
