    Vine weevil. Not good. Not good at all. As you are lifting the tubers then the best course is to wash off all the soil and remove all grubs. Either squish them or feed them to the birds. Unfortunately if you found them in your begonias then they will also be present in other pots and you need to take action there too.

    They look like the dreaded  vine weevil grubs. They will chew through all your roots. Pick them out and feed to the birds or drown them  in boiling water.

    It's not a mess, it's a nature reserve.

    They love fuchsia so if you have any of those, i would take them out of the pots and check.

    Gardening on the wild, windy west side of Dartmoor. 
  • Ah. Vine weevils. Lovers of the roots of many plants. Rhodedendrons. Strawberries. Lots of others. Hated by gardeners. The grubs are loved by hens.

    If I remember correctly they (vine weevils) have the same reproductive technique as aphids - parthenogenesis. The adults are female, do not require fertilisation by males and lay lots and lots of eggs. At this time of year, nematode control treatments won't have an effect - the temperatures are too low for the parasitic nematodes to breed/thrive. Begonia tubers can be lifted, washed and dried then stored in a cool place for next year.

    Dispose of the compost. It'll have dormant weevil eggs awaiting warmer months.

    Most of the vine weevil treatments are parasitic nematodes. These don't respond well at this time of year. Spring would be the time for them.

    Provado Vine Weevil Killer is the way to go. Kill all the grubs you find, pour boiling water of the rest and then use Provado. I would also clean the tubers with running water to make sure you get the egss (too small to see) as per above. They really are a pest. Not nice to find a loved plant munched to death at the roots.
