Tiny yellow spots on leaves: pests or disease?
All leaves of my primroses, some roses and catmint this summer got covered with tiny yellow spots (see attached). Rhododendron, Azalea and Begonia are intact. I thought it's a whitefly and used Rose Clear Ultra and Provado Ultimate Bug Killer to cure the plants( but with no success) and cut the catmint to the roots.
Did anyone encounter the same problem in the garden? What's this? Is there a chance these pests will die over the winter? Please help |

Examine the bottoms of the leaves with a strong magnifying glass. +-------------------------------------------------------------------+ |Filename: P10300171.jpg | |Download: http://www.gardenbanter.co.uk/attachment.php attachmentid=14440| +-------------------------------------------------------------------+ -- Pat in Plymouth MI "Yes, swooping is bad." email valid but not regularly monitored |

Thank you very much for your replies! Looks like spider mite. I'll try the Scotts Bug Clear Ultra Gun" insecticide to get rid of them.
