My family traditionally cuts wood strups to size for each stretch where you want lights. Paint the wood to match your home. Attached the lights with Command hooks. Then all you have to do is drill holes into the end of the wood strips and matching hooks into your home. You just put the strips up every year, quick and easy.

How do you attach the wood strip to the house?

This seems to have been reborn. We just had our stucco home repainted and I have a few
things hung from those plastic plugs. To avoid then patching the holes or filling the plug with paint, I found that the bamboo shiscabob sticks I had fit perfectly. I cut a six inch piece and sharpened the end with a pencil sharpener. I tapped it into the plastic plug with a light hammer and then cut it off, 1/4 inch proud with sharp pruning sheers. What was cut off, back into the pencil sharpener sand used to cover the next plug. Quicker to do than to describe. It worked fine. Grab the end with pliers and it pulls right out leaving the reusable plug. Surely a dowel stick would work as well.

You could try hot melt glue. It won't put a hole in the stucco like some other suggestions.
I would try a spot in an inconspicuous spot first.
Good luck!

It is amazing. that snot kind of stuff that catalogs and magazines put stuff in with....that stuff will hold small children to the wall I swear!
