I can see that you haven't started painting yet, who knows you might be going to treat anyway. However that WAS my big mistake, not treating. I urge new beekeepers I come in contact with to treat before painting. What they do after that is up to them. They can't say they weren't warned.
PS @Bobby_Thanepohn, did you manage to get #9 & #10 up there without a stool? I can manage 8.
