My nasturtiums have been decimated by cabbage white caterpillars, so I've started to pull them up...BUT... if I remove their food source, will they move on to other plants? I don't have any brassicas

They need to eat something so I leave them as food providers.

Don't think so. Just enjoy the flowers for another few weeks - winter's a long time without any...
