I wish I knew. I was so proud of my columbines, and then yesterday I noticed the leaves were showing signs of leaf miners again! I'd like to put a stop to that!

Least Toxic: Insecticides are rarely recommend to control leafminers. Since the damage is mostly cosmetic, the remedy is to remove the affected leaves. This does more than improve the appearance of the plant. It also gets rid of the existing leafminers before they become adults and lay more eggs.
Less Toxic: If you know that a certain plant is susceptible to leafminer every year, you can target the adults before they lay their eggs, by spraying early in the spring with an insecticide such as neem.
Last Resort: There are some systemic Insecticides that are labeled for use on leafminers. Insecticides containing acephate (Orthene) or imidacloprid can be effective if used before damage is severe. No systemics are currently available for non-commercial use on edible plants.
