I get the grubs in pots (more so this year than previous years) but have never seen an adult vine weevil here. Mind you, I don't do early mornings and rarely go out at dusk as allergic to mosquito bites!
The long border in this garden was badly infested with vine weevil when we came here ... four years ago we made two applications of nematodes ... they worked and we still have no problem with vine weevil, despite growing a lot of plants in containers.

We bought ours via Amazon ... you will also need a watering can with a rose with large holes as the nematodes in solution will block the holes of a fine rose and you'll just be watering your beds rather than applying the nematodes. Good luck

It is a bit late now, the grubs are turning, the ones I’ve found recently were getting their legs. If you’re quick it will be ok. The next best time to use then is end of September into October when there will be a fresh lot of grubs hatched.

I'm not questioning your claim, I was just showing some leaves from my garden that have been chewed by Vine Weevil that are semi circular in shape with a serrated edge.
And just so there's no confusion, these are some of my Black-eyed Suzi that a Leaf Cutter Bee took a shine to.
It does seem to have been a bad year for them. Or a good year for them and a bad year for us. You know what I mean. There's tons of the buggers about. I've been checking my sedums and 6 or 7 plants had no root system at all. The problem with sedums is they don't mind having their roots eaten so you don't know the grubs are there until you move the plant and the top growth falls onto the floor. I've still got some plants happily flowering with no root left at all. Once the root is all gone though they tunnel up into the stems so you have to check everything thoroughly if you want to save the plant. The garden robins are now my best mates after having a grub feast.
I don't use controls of any kind as I'm not convinced nematodes are a good solution given they don't just attack vine weevil grubs. Who knows what other effect they will have on your soil ecosystem.
If you can keep your head, while those around you are losing theirs, you may not have grasped the seriousness of the situation.
