Strawberry bed - Strawberry sawfly

This year my strawberries in the garden pots have been devastated by sawfly. Seems though that if I can get rid of the fly/larvae, the plants will be good next year. Given I now have the allotment space for a decent size strawberry bed - is it possible to transfer the pot strawberries (including quite a lot of potted runners), without taking the sawfly too? How?
