Brown Spots On House Siding

The fungus sets its sights on bright areas so that means it will aim for any pale surface that reflects light such as the siding on your house.

Brown spots on house siding.

These crickets are light brown tan and dark brown with a humped back. I thought it was bird droppings at first so i power washed it off. Now there is a section on the second floor we ve seen it a couple of other places but it s most concentrated in one area that has reddish brown liquid lines running down from under the siding. Artillery fungus is a wood dwelling fungus commonly found in mulch.

What it looks like. When water runs through the wood and wall sheathing it picks up tannins in the wood and leaves dark stains on the siding. If you notice lots of tiny black or dark brown spots developing on your siding above a landscaped area of your yard as seen below it is most likely artillery otherwise known as shotgun fungus. Since then there haven t been any issues with the siding however a week ago i noticed a bunch of brown streaks stains on the east side of the house.

Some tell us it s from spiders. If the home experiences ice dams and the stains start at the soffits and run down the siding they re probably the result of water leaking through the roof as a result of the ice dams. My family and i built our new home we general contracted it and we moved into it in november of 2015. They have very long antennae and their bodies grow between 1 2 to 1 1 2 inches long.

Seeing black tar spots on the sides of your house or vehicles. The spots are about the size of the head of a pin and appear to be black or dark brown in color. I have often seen red or brown stains from water leaking down behind building siding on older homes. The black tar like spots that are all over your vinyl siding are more than likely a fungus called sphaerobolus stellatus better known as artillery or shotgun fungus.

I have tried to remove these spots with mineral spirits without. Also known as artillery or cannonball fungus sphaerobolus it uses internal water pressure to forcefully fire its spores similar to seeds up to 20 feet away. Others have said it s a fungus from mulch. Most often the root cause is wind blown rain condensation or frost accumulation behind siding that was not installed over a modern housewrap water barraier.

Although it s most often found on the east coast it can grow anywhere and especially thrives in areas that have cool damp springs or rainy fall weather conditions.
