Can you tell me what to do please if you think you have vine weevil in the ground not in pots ? I keep losing plants that have all the roots eaten although can't see any weevils in the earth . (moving house seems a bit drastic!)
Nemasys vine weevil treatment is for open ground as well as for pots. From a small pack you will be able to treat 160 pots or 12 square metres. You can also buy Nemasys Vine Weevil killer in larger packs for larger areas. As said before though it will not be effective below 5*C. You will probably also find that the product is not available now until the Spring of 2016
A word of warning, folks - Provado is being withdrawn at the end of the year and so far there's nothing to replace it. It's probably illegal to suggest you stock up now, so I won't say it!
When we moved here we discovered one of the beds infested with vine weevil - mainly affecting the primulas - we applied Nemasys twice that year (now three years ago) and have had very few problems in the bed since.
However this year I have found a couple of grubs in pots of fibrous rooted begonias so next spring, as soon as the temperatures improve I'll treat the beds again.
My plan is to keep the 'background level' of weevils down and that way that they don't spread to the pots and tubs of bedding plants in the summer.
Sort of using the bedding plants as an 'alarm' if you get my meaning
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Have been reflecting on the subject of the type of soil/compost.
When we first moved here the area which is now the Shady Bank had a very high level of organic content, not having been 'cultivated' or the fallen leaves cleared up for probably 30 years. That was when we found a lot of evidence of vine weevils and the Nemasys was first applied.
The following year we dug that bank over and extended it, building a retaining wall along it's length. We had at least a couple of tonnes of topsoil added and dug in before the bed was replanted. The topsoil was quite a gritty loam.
I wonder if the gritty soil has made the vine weevil larvae feel less at home and has contributed, along with the Nemasys, to the reduction in damage.

This is why I try to keep on top of the problem and use longer term solutions.
Are you sure your soil temperature in Cornwall is too low at the moment? http://www.greengardener.co.uk/product.asp?id_pc=22&cat=46
According to that link it's still fine to apply it to the soil in Suffolk at the moment.

I think you're definintely right about the garden soil - I don't think they like gritty composts
MPC makes them too comfy.
