pin head size black dots on the south side of my house
We have pin head black dots on the side of our house. If you scrape them off the dot has removed paint.
What is it?
Outside United States mildew and mold control
Without a picture it is difficult to tell what these might be, although it does sound like it might be artillery fungus. I've included a link to a page about artillery fungus- you may want to google search for images of artillery fungus on homes to see if that matches what you have.
I am also including a link to a page that lists various methods individuals have tried to remove the artillery fungus.
Hope this helps,
