VERY tiny black flies
These flies are no bigger than a speck of black pepper. Moved plants into this room about 3 weeks ago. Never had problems in the other location. Have "rustled" the leaves of the plants and no flies appear. They are so very small. Not as fast as a fruit fly. We can swat them.
i don't have enough information to say. Couple questions:
Were the plants outside?
Can you send a picture of the insect or bring some to the office?
