The third way is to put a layer of neem oil in a jar with castile soap and water and us a paint brush to apply the solution. Stir up the neem well so that the soap disperses the neem bilayer into the solution. This is a good method for kids who want to help out in the garden, because it trains them to look carefully at the plants and conserves the neem solution. It takes a few days of regular treatment to eliminate the leaf miners. You know you can stop when the infested area turns brown and dries to a crisp. The plants below were treated by my kids with the paint brush method.
