What Are The Black Dots On My House?

Artillery Fungus

As a power washing company, we understand the importance of keeping your property looking clean and well-maintained. However, there is a problem that many homeowners face that can be particularly stubborn to remove: artillery fungus. In this blog post, we’ll explore what artillery fungus is, how it can damage your property, and what you can do to prevent and remove it.

What is Artillery Fungus?

Artillery fungus, also known as shotgun fungus or sporella, is a type of fungi that grows in wood chips, mulch, or other organic material. It’s called “artillery” fungus because it shoots tiny black spores up to 20 feet in the air, which can then stick to surfaces like siding, windows, and cars. The spores are small, but they can create a big problem for homeowners.

How Does Artillery Fungus Damage Your Property?

Artillery fungus is particularly damaging because it’s difficult to remove. The spores can stick to surfaces like glue and are not easily washed away with water or soap. If left untreated, the spores can cause permanent damage to surfaces like siding and windows. The tiny black dots can also be unsightly, giving your property an unkempt appearance.

How Can You Prevent and Remove Artillery Fungus?

Prevention is the key to dealing with artillery fungus. Here are a few tips to keep in mind:

  1. Avoid using wood chips or mulch near your home’s exterior. Artillery fungus thrives in organic material, so choosing a different landscaping option can help reduce the risk of spores sticking to your property.
  2. If you do use wood chips or mulch, choose a different type. Cedar chips are less likely to harbor artillery fungus.
  3. Keep your property clean. Regularly power washing your home’s exterior can help remove any spores that may have landed on your property.
  4. Remove any organic material that’s already on your property. This includes any old wood chips, mulch, or leaves that may have accumulated.
