• The

    Times

    called 2022 “the year of the wasp in France”.

    Why ?

    Because the insect is one of the big topics of discussion for the French this summer because of its number.

  • However, the specialist in the study of insects, Henri-Pierre Aberlenc, does not observe any particular increase in the number of wasps on the territory.

  • According to him, the idea of ​​a "wasp invasion" comes mainly from our fear of this small insect.

    A fear that is not always justified.

Coffee grounds, copper object and plastic bottle trap, etc.

At the table with friends, at the office, as at the beach bar, we share the best tips to ward off this insect that absolutely wants to share our grenadine: the wasp.

And if we talk about it so much it's because this year, for many, the wasps would be particularly numerous.

In the Marne, the Guêpes-Apens company (which was awarded the medal for pun of the month) ensures that its activity has increased by 50% in the department.

Even the English newspaper The

Times

assures us that wasps proliferate from the Mediterranean to the Channel coasts, declaring that 2022 was "the year of the wasp in France".

But at

20 Minutes

, apart from the fact that we don't really like the English telling us what to call our year, we wondered if this invasion had really been observed by experts and not just by your uncle who has some tired of not being able to have a quiet barbecue.

On the other hand really, from France to Austria, SYSTEMATICALLY there is a FUCKING wasp that shows up wherever we stop.


What's the deal with the wasps this year you say?

Do quantified studies prove that there is a global invasion of wasps throughout France this summer?

No.

Anyway not yet.

And anyway, it would be quite complicated.

“We cannot generalize since there are quantities of very versatile wasp species”, explains to

20 Minutes

the entomologist (that means specialist in the study of insects), Henri-Pierre Aberlenc.

The author of the manual Les Insectes du Monde, has identified hundreds of families of wasps in France “in the classic sense of the term”.

That is to say the black striped yellows, if we completely popularize the species of vespids where we can however distinguish the Vespa Crabo from the Vespula germanica.

Some will thus cope better with global warming than others.

Everything will also depend on the region where you are.

“Wasp populations, like any insect, fluctuate wildly from year to year.

This fluctuation is occasional, local and cyclical”, insists Henri-Pierre Aberlenc, who says he has not observed any particularly this year.

In fact, it is enough that it is hot or humid at the right time, in the right place for the population of a species to be important and another much less.

Why does it feel like there are more then?

In summer, our observation of the wasp population is often biased.

Firstly because if we are on vacation and it is hot, we are generally outside to eat and bathe for example.

Two things that attract wasps.

"Sources of meat or sweet food can concentrate a lot of wasps in the same place, as can the water points where they come to drink in these times of drought", analyzes the entomologist.

Except that sharing your rib steak or swimming pool with these little buzzers rarely enchants people.

Not because they are selfish, but because the wasp sting is scary.

Yes, no one will ever complain about an invasion of pretty butterflies or little kittens.

However, "only female wasps sting", recalls the expert, "and only if one approaches less than two meters from their nest".

No risk of being stung at the table therefore, unless their house is just below.

Why should we rejoice that there are so many?

The wasp is an insect and “over the long term, on the scale of decades, beyond local events and annual fluctuations, there is a general decline in insects”, observes Henri-Pierre Aberlenc.

The wasp, an omnivorous animal like us, “plays a useful role in regulating the populations of other insects and is prey for certain birds”.

French wasps are an essential part of our biodiversity and the balance of nature.

Henri-Pierre Aberlenc recommends not systematically having a wasp's nest removed as soon as one is spotted, but to first analyze whether the latter is in a place where you have to pass less than two meters.

If it's dangerous, call a specialist.

If not, then no risk.

So, are you going to share your lemonade?
