I've had extremely good results by drowning the buggers.
First I tested how long they last in a jar of water (they sink) - not much more than a few days.
Strawberries can survive being waterlogged for much longer than that!
In Spring and Autumn you simply have to find a container bigger than the pot and immerse the whole thing - a week is more than enough - much less if you use manure water that leaves no oxygen for the weevils.
It's particularly good for fancy strawberry pots where there is a big investment of time in getting the layers right - even if you overdo the drowning and kill the plants it's so much easier to replace them than rebuild the layers.
Hope this helps.
Cheers.
~I~ usually bet on 24-48 hrs doing it. Perhaps i'm too optimistic... ::)

Maybe I'm too pessimistic? I've definitely managed to kill the weevils without killing the strawberry despite this, but strawberries are pretty tough.
If I was dealing with something that really couldn't stand waterlogging it would definitely be worth cutting it finer.
With a small number of vine cuttings it's actually easier to knock them out and wash the soil out.
Horses for courses.
