  • Help..Pest on my runner beans in greenhouse

    They are just in transition to outside thanks to frosts , but since putting them in there they have developed a pest. The greenhouse hasn't been fully cleaned yet.
    A spider , grey ? Was on a leaf tonight . Not sure if he is the culprit or trying to catch the culprit .
    Leaf images.
    The holes one is dwarf bean, rest are runners.

    What can I do ? Bring back in house? If I plant out its too soon here. Due 5deg nights (which is usually less).

    Slugs or snails. Check underneath the pots...they love beans.

        The spider is unlikely to be the problem as spiders are generally meat eaters. It doesn't look like slug damage to me - slug holes usually start at the edges of the leaves.

        The only thing I can find that looks remotely like it is bean leaf beetle damage. However I wouldn't expect this to be a greenhouse pest and it seems to be an American thing - I've not heard of it in the UK. So basically I have no idea what is eating your plants, but it doesn't look huge damage at the moment and is unlikely to affect the crop unless it gets much worse.

            I have holes like these on my beans too, but deffo from slugs. there are many tiny slugs in the garden, so small I cant even collect them when I am on slug hunting. And tiny, tiny snails, my guess is they make these holes, baby slug amateurs!

              My French and Runner beans have had that damage, can assure you it's deffo snail/slug damage as I've got the same problem. There's certainly an explosion of the population happening right now so there is going to be more of this showing. Some of my french beans ended up with no foliage just the leaf stalks but its helped them to send out side shoots so I should have a better crop as a result. Some of the damage has been just holes in the leaves exactly like you have.
