I watched the Beechgrove Garden last night, in which they were commenting on red spider mite on a peach tree in their greenhouse. I realised I've got the same thing on my cucumber plants in the greenhouse - webby stuff around the leaves at the tops of the plants.

What should I do about it? The plants do still have quite a lot of small cukes on them, though I suppose the season isn't going to last much longer.
