Answer: It's hard to tell from your description, but I wonder if the pests are thrips. Thrips: Thrips are brown or tan, about one-eighth of an inch long. They're very narrow, appearing the shape of a tiny alligator. They're hard to see with the naked eye, but their damage is very clear. Thrips chew the top surface of leaves, leaving a striped, tan dead layer of leaf behind. The damage can appear as ?white spots' on leaves, or a lacy or skeletal appearance on the leaves.
Control: Insecticidal Soap will kill thrips very effectively. Repeat about every three days to kill young thrips hatching from existing eggs on the plants.
