Plant SOS. How can I kill spider mites? ?
Spider mites love dry environment, they don’t survive in the wet or damp predator mites will get rid of them, they can be bought at a good garden centre, and by mail order, but you can help by spraying your plants with cold water on a regular basis, these mites are difficult to get completely rid of, I had some real problems with peaches but they don’t see to bother with my tomato plants, try misting the rose bush with a hand trigger type spray with cold water as often as you can and get underneath the leaves, these insects are very tiny and some need a magnifying glass to be seen, but they are very destructive, try the cold water treatment.
