Spiders Sunny

Spider mite SOS!!?
Dear Gardening Friends,
Does anyone among you know of a surefire method of getting rid of those most tenacious and dangerous of all pests, the spider mite? We have two 7 foot-high oleander on our terrace (we’re in Switzerland, where the summers are hot; the plants spend the winter in a greenhouse), which we’re trying to rid of spider mites once and for all. We’ve tried everything from horticultural soap to the most lethal insecticide. We’re now reduced to hand-picking these creatures off each morning and evening – a procedure, which always yields about 10 mites per plant. My worries don’t just concern the oleander, but also the lemon tree and callistemon, which both share the same sunny terrace side. How grateful I’ll be for any and all suggestions you might have!
Thanks from a weary plant lover.
Your problem can be solved by getting Lady Bugs. You can order them off the Internet. They love to eat mites and you will not harm plants or other life by using chemicals.
Good luck.
