Amar - The damage on the traps look very similar to my red spider mite infected plants. To help you find the critters, try paying close atention to the new traps that are emerging from the centre of the plant, I found more spider mites seemed to congregate there. They look like tiny tiny red specks, but you can see them with the naked eye.
Thankyou for this advice. I have previously tried drowning plants and using provado, but both were inaffective. However, bug clear gun seems to have done the trick, finally!...I was beginning to despair.
