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
