Donna,
I don't have an answer definitive answer for you but that does not look like slug damage to me, are you seeing the slime trails on your leaves? Could it be earwigs, you might check to see if you have any rolled up in a leaf. I must say to me your bee balm looks super happy and healthy. We have had so much humidity I can't believe you don't have powdery mildew. kt

bite your tongue!!! lol, I spray religously. Your right. I have found out it's earwigs. How do you get rid of them?

donna,
I have been poking around and doing a little reading as I haven't had or more likely noticed earwig problems in many years, but as I recall I used toilet tissue/paper towel rolls to lure them each night and in the morning I would empty them else where. Earwigs are beneficial to your garden as they eat the pesky aphid so unless they are really wreaking havoc you might decide to tolerate the minor damage.

What do you spray with?

runktrun, I am so greatful to you for telling me this. I had no Idea they were beneficial. They go into an empty roll?
evonnestoryteller, I spray with bannermax/mancozeb, same as I do for my roses. I feed just about anything that breaths and have never seen any harmful effects to any of them.
