Two-spotted spider mites in berry crops: IPM guide

This resource was developed as part of a 12-guide series for small-scale vegetable and berry farmers in the Fraser Valley and Lillooet-Pemberton areas. Growers in other regions of BC may also find the information applicable to their local conditions.

Two-spotted spider mites (TSSM; Tetranychus urticae Koch) feed directly on plants and can cause damage on a range of crops, including strawberries, raspberries, blackberries, eggplants and cucumbers. They can cause serious yield loss in high infestations.

This guide contains integrated pest management (IPM) information tailored for small-scale production, but the guidelines can be applied to all operation sizes. It includes:

  • Identification and lifecycle details including photographs of pest phases
  • Information about how and when to monitor
  • Options for biological, cultural, physical and chemical control
