-Remove leaves that are more than 50% damage from the plant and room then destroy them. Making sure adult mites and mites form hatched eggs do not reenter the garden.
– Spray foliage especially under leaves with high pressure cold water ( as high pressure as the plants can take without ruining them ) to first knock off as many as possible.
( If only one or two plants are infected isolate them immediately and treat them separately. )
