    My lovely variegated nasturtium is being eaten covered in caterpillars. They are small and green with black spots. Are they good or bad and what can I do? gingergoose

    Hi, they are quite likely to be caterpillars of the Large White Butterfly and are often found eating cabbages and other brassicas. See link: https://www.rhs.org.uk/advice/profile?pid=457 Blackstart

    Thank you Blackstart. I had read the link thank you. What I was asking was what is the quickest effective thing to do. I have got nearly nothing left. gingergoose

    Depends how many of there are. Can you pick them off and put them in a wheelie bin? I don't like to use chemical pesticides if possible so you could look for one of the bacteria based products, see link: Blackstart https://www.google.co.uk/search?rlz=1C1VSNG_enGB650GB651&q=bacillus+thuringiensis+products+uk&oq=bacillus+thuringiensis+products+uk&gs_l=psy-ab.3...1224.3619.0.4107.3.3.0.0.0.0.103.257.2j1.3.0....0...1.1.64.psy-ab..0.2.176...0j33i21k1j33i160k1.Wg66NdvbMcU

    Thanks. The plant is vurtually dead now. It's such a shame as it was so lovely. I live out in the sticks and cant buy anything quickly and I needed to do something straight away and hoped someone could give me their personal experience. I just found some Provado and was going to use that but its been pouring with rain since. I did notice a lot of eggs on the stems but they are black and not white as per the description of the cabbage caterpillar. The caterpillars looked like cabbage caterpillars pictures on the internet. gingergoose

    I have had some success. I picked off every one of the caterpillars on Blackstart's advice. I didn't much fancy putting them in the wheelie bin as he suggested so took them to the field. When clear I sprayed the plant with Provado. The plant looked much better today and the dear little thing opened a couple of new flowers. Can someone please tell me what the black eggs are? Thanks for help gingergoose.

     Suspect noine of the "Forum" users know Without a picture it's difficult.They might not be eggs being part of the plant. I'd keep an eye on them and see what pops out, if anything, as eggs they will do no harm to the nasturtium.

    Thank you Nigel. The caterpillars did enormous damage to the plant and almost killed it. The "eggs" are not part of the plant as you suggest they are part way along the smooth stems. I asked the question because the caterpillar was identified as the cabbage caterpillar and it looks like the internet pictures but it says their eggs are white. Be glad of some help. my goose

     If they are really worrying you scrape them off with a finger nail. I'd leave them out of curiosity to see what pops out.

    I thought cabbage butterfly eggs were yellow? Maybe I'm wrong. I have discovered there is also a Cabbage Moth which looks completely different. I wonder if they are these? Or is it the poo from something, even a snail or slug?

    Thanks Minnie.

    This picture of cabbage caterpillars is what I had.

    https://www.rhs.org.uk/advice/profile?pid=457 

    Their eggs are usually a yellowish white. I did manage to pick off every one and put them in the field

    The black eggs are definitely black eggs, not poo. slugs snails or anything else. I guess I will never know.

    Thanks for help.
