Brown Spots On House Siding

We have thousands of tiny black spots pin head size all over the siding of our house.

Brown spots on house siding.

They have very long antennae and their bodies grow between 1 2 to 1 1 2 inches long. I e not entire house. They are the reproductive structures produced by artillery fungus sphaerobolus stellatus one of several fungi common on wood mulches used around plantings in home and commercial landscapes. This may be where it s stemming from in your yard as you mention that the fungus seems to be limited to growing on the siding closest to your mulch beds.

What it looks like. Many bites occur because the spider is hiding in folded towels. The brown recluse likes to hang out in undisturbed corners of homes in sheds and in basements or cellars. We have a problem with our siding on front and back of our 2 story home.

Others have said it s a fungus from mulch. The photo at above left shows green algae on vinyl siding. The dark spots are indeed spores but they do not come from your oak trees. This mostly happens during cool rainy spring and fall seasons especially in shady areas so you re most likely to find it on the darker north side of your house.

Some tell us it s from spiders. Algae may also look black or brown as may some molds. These crickets are light brown tan and dark brown with a humped back. Where you ll find them.

This fungus can grow on multiple surfaces including wood siding fences decks and cars. 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. It is occuring on first floor only same area in front as in back. Artillery fungus stops making spores when the temperature is over 78 f so you will get a break in the summer.
