Please help me identify these spots

Deer Park, TX

For a few years I have had groups of these spots on the outside of my house. I first noticed them on the pole by my front door. I tried to wipe them off, and it was kind of sticky. I tried to look them up on google, but since I didn't really know how to describe them, didn't have much luck. The closest I could find was that it is some type of fungus that could originate from compost or soil. The problem is that the pictures they were describing look like bigger bumps (for lack of a better way to describe them), and darker. The ones on my house are always in groups.

I don't know if this is the right place to post this, but I read over the names of other topics, and couldn't tell where it should go. Thanks for your help.

I get these on my house sometimes too. I believe them to be some kind of spider eggs. Although I can't find a picture of them online so they could be some other bug I suppose, it's just because of their location I always thought they were some kind of spider.

Maybe someone on the insect/spider ID forum could help. From the second picture it definitely looks like some type of insect eggs.

Since you mention Compost and Soil--my mind went right off to the possibility of a mulch-born
fungus called "Artilery Fungus" which "shoots" out "stuff" from the growths.

Look it up--as one of the main complaints has been that it messes up house walls and siding with
whatever it is made up of.

Just a wild guess----but i di not think it is insect caused.....

I Googled "Artilery Fungus"---it--see if these links help:

May be something else completely--but this is a good possibility.

Yellow, can you try for a close up pic of the spots? That would better aid in determining if the spots are fungal or insect.

Thanks for all your replies. I had an unplanned surgery, and haven't been on here for almost a month. Gitagal, I read about artilery fungus back when I first noticed them. The reason I don't think that's what this is, is because the artilery fungus looks black and seems to cover a large area. The spots on my house are grayish/tannish, and a group of many spots is about the size of a nickel. Themoonhowl, I will try to get a close up picture and post it. Thanks again, everyone.

themoonhowl, I tried taking close up pictures, but they are all blurry. My camera is a pretty simple one. I can't figure out how to get it close up and clear. I'll see if I can get some help. Thanks for the suggestion. A close up would definitely make it easier for it to hopefully be identified.

Does your camera have a Macro setting? Most cameras do.
The symbol for the Macro is a small flower.

Look in your settings somewhere.....Gita

Here is a close up picture. Gita, thanks for that suggestion. My camera doesn't say macro, but it said autofocus, so I tried it.

The entire group of spots is just over half an inch in diameter.

It could very well be moth eggs. They are notorious for using walls as repositories. It does rather look like the eggs are no longer viable though.

Hmmmmm....A wild thought....

Just an idea. It looks like something wet was on the siding, like bird poop, but it contained the small
seeds or granules.
Then the wet/moisture dried out leaving only the granules. I know sea gulls are notorious poopers on cars and anything else.
Like i said--a wild supposition.

Have you picked one of those dark thingies off to see if it is a seed?

Have you tried washing these spots off with soap and water? Did it work?

OK! Out of suggestions... Gita

Gita, I tried to wipe it off with my hand back when I first noticed them, but they were sticky...yuck! This is on the underside of my porch, so it's not in a location where a bird could poop. However, the bird poop is a good idea, as I understand what you mean about them leaving things behind. I can always tell when birds have eaten berries. :) Thanks and I appreciate you taking the time to throw out ideas. I've really been grasping at straws because they seem to crop up overnight.

themoonhowl, I bet you are spot-on. There are several groups of these around my house. I feel like I'm fighting a losing battle with moths. It's been going on for over a year. This is going on my husband's "invisible" honey-do list. (I'm still recovering from surgery, so it's hard for me to reach up.) Since the first time I tried to wipe them off and they were sticky, I haven't touched them. Thank you so much!!
