What are the black dots on my siding?
The black dots on your siding are most likely spores from a ground growing fungus called Artillery Fungus (also know as Shotgun Fungus). This fungus is usually found growing in mulch around your home. The fungus shoots its spores into the air 15 to 20 feet. Once the spore hits your siding it attaches to it. Removing these spores is extremely difficult and time consuming. There are no known products that are effective in removing them. We cannot guarantee that these spores will be removed when we clean your siding. The best way to fight this problem is to remove your mulch and replace it with a different type of ground cover. If you are set on using a wood based product it is recommended you use mulch that is greater than 85% bark.
