Spiders on plants in Greenhouse

[Andrea G]

I am growing several pepper plants in the greenhouse but over recent weeks the leaves have become shrivelled & clearly infected with something although I can't see any insects with the naked eye. I noticed a few days ago 3 or 4 spiders on the plants (fairly small spiders with a white body). My problem is - are the spiders doing the damage or are the spiders eating the pests doing the damage - i.e. do I need to remove the spiders. Any suggestions please?

The spiders you can see shouldn't be doing any damage, so leave them be. I think you may be confusing them with red spider mite Glasshouse red spider mite / RHS Gardening Advice
