I'd rather use nematodes - they worked for me last year on a really bad infestation of a bed of primula deticulata and vialli. I'll use them again this year as soon as the soil warms up and hopefully that will really have knocked them for six.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
