|Leafminers are the larvae of a specific type of fly. The adult lays the egg by piercing the surface of the leaf. The egg hatches into a larvae which feeds on the tissues between the upper and lower surfaces of the leaf. Because it is protected inside the leaf, no sprays will touch it. Instead of going after the larvae, you'll need to keep the adult from laying her eggs. Difficult - but not impossible. You can either time your lettuce plantings to avoid the insect's active flight time (plant in very early spring or in the fall) or you can use a row cover such as Reemay over your lettuce crops to act as a barrier between the flies and the lettuce leaves. Best wishes with your lettuce.
