Entomology Bulletin 2006.
The INPN had been keeping track of sightings since 2004.
The nest located in Lot-Garone in 2005 was eradicated. Sightings in winter of that year and capture of vv queens in spring of 2006.
On the INPN page you have a lot of data, even so I do not expect (since I am not delusional) that you will change your attitude/opinion, but at least I have made it clear that the data is for those who want to get closer to reality.
