Answer: Basil has a reputation as an insect repellent, particularly for mosquitoes. Despite its insect repellent properties, basil is subject to a variety of pests, including Japanese beetles, grasshoppers, slugs, aphids, spider mites, whiteflies, cutworms and nematodes. Since you will be consuming the leaves of this plant, there's really nothing safe to spray on it. I would remove the shriveled leaves and pick off any pests you might see. Best wishes with your basil.
