In the summer time I try and get more creative and when ever possible I'll climb onto a roof or go by the water for example.
Except when I'm working for this one particular elderly couple. I don't even pack my lunch because they always cook for me.
Edit: Done
If it's a white wall, the easiest fix is to just grab some white-drying filler, fill the holes, and leave it at that. It'll be nearly invisible - your eye won't catch it the way it does a dark hole.
The filler shrinks as it dries, so you'll need to layer it over a few days until it sits flat when dry. Done right - and without overdoing it - you won't even need to sand.
For non-white walls, same deal - just paint over it afterward. Note that matching the existing color perfectly is nearly impossible. For good results, you usually need to paint the entire wall.
