We’ve spent almost the entire time we have lived in our house wondering what these little black dots were on our vehicles and the siding of the house. They are extremely sticky dots, and the only good way to get rid of them is to scratch them off with your fingernail. Last week we had the house power washed in hopes that the cursed dots would be gone, but of course, they stubbornly remain.
Someone I work with mentioned it might be mold, which I quickly dismissed due to the location of our dots. How could mold grow on siding and vehicles, where it gets direct, hot sunlight? So, I began searching the Internet. Lo, and behold, we found out what our little black dots are –
artillery fungus.
I’m going to do some more research, but another one of my co-workers who has experience with this stuff suggested spraying the infected siding with a solution of bleach and water, then treating it with a product called Trisodium Phosphate, aka TSP. I’m going to test a small area this afternoon to see if the bleach is damaging to the siding, but I’m really hoping this works!
