I am having the same problem this year too on my eggplants. This is what they look like:
What It Is: Safer® Brand Insect Killing Soap with Seaweed Extract is a special formulation of insecticidal soap. This ingredient kills insects, yet is gentle on plants with no unpleasant odor. What It Kills: Aphids, Earwigs, Grasshoppers, Harlequin Bugs, Leafhoppers, Mealybugs, Mites, Plant Bugs, Psyllids, Sawfly Larvae, Soft Scales, Spider Mites, Squash Bugs, Blossom Thrips, and Whiteflies.
Yeah I did use sevin also.
‘Sevin’ isn’t available everywhere, anymore. Stupid EPA!
A good replacement is ‘Eight’ spray made by Bonide. Kills flea beetles dead!
