I have a spider mite problem. I have a small backyard vegetable, herb and flower garden in Baltimore City. In the past I've been able to keep the spider mites targeted to marigolds and have controlled the spread with insecticidal soup for organic gardening. This year, this strategy is not working. The marigolds are still bearing the brunt of the "assault," but the mites are spreading. My tomato and mint are being hardest hit. Do you have any suggestions for spider mite control beyond spraying regularly with insecticidal soap? Thank you!
When your insects become resistant to one insecticide, try rotating to another insecticide. The three organic insecticides that you can use for spider mites on all the plants you mentioned are insecticidal oil, insecticidal soap, or Spinosad (also organic.)
