Not a plant but a mystery spore or fungus?! (ID complete) (moth eggs)

Please HELP … what in the WORLD is happening in my back yard?? There is a strange spore/fungus that is growing in patches in various odd places, specifically wood (even cedar) and plastic materials (example, on my kids playground slide). We have seen several small mushrooms growing in the grass and parts of the back yard is moist in the shaded corner of the yard. We have Zoysia. It is so bizarre … please help, anyone?? See the photo attachments – these are images of the spores growing on the cedar swingset. Thanks so much

    looks like moth eggs to me…..have you seen many lately?

    Does anyone you know have a camera with a macro lens so you can get closer to the item and stay in focus?

    Moth eggs? Wow, I never even considered that. Trust me, I am relieved. I wouldn’t even let my kids go in the back yard. I was worried it was a dangerous mold spore or something. This makes a lot of sense as I have seen a lot of moths back there. Here’s the strangest thing … these “eggs” are usually on the underneath side of a surface – the side that is close to the ground and does not get direct sunlight. Would that still make sense that it would be a moth egg? I can’t thank you enough for your input! Thanks Walter.
    By the way, the close up photo is pretty high resolution and I can zoom in a lot closer. I’ll see if I can repost it. Thanks.

    How do I prevent these moths from laying eggs? Every time I scrub the this cedar play set, the moth eggs are back within two-three days… just as bad. I sprayed “Sevin” on it, and all over the play set, but it didn’t work. Any advice? Or, will this get resolved when the first frost hits? Will they come back next year?

    I am having this same exact problem. I think the moths came with a cedar playset that we purchased and was delivered from Georgia. How do I figure out what type of moth eggs these are? And, how do I get rid of them and prevent more eggs? They are ALL over my playset and the wood parts of my house. Will they cause damage to my house? They are EVERYWHERE.

    Jessica – I feel your pain because it is very stressful and disgusting. The moths did eventually go away (cold weather and frost) but we did have to work on it. We ended up having to use sealer on the playset which really worked the best. We scrubbed the playset with hot soapy water to remove the moth eggs first. Then as soon as it dried, we sprayed sealer on it – several coats. There were several patches on our house trim and doors too, but it will not do damage. Just scrub it off. The moths were still by the hundreds in our yard but we sprayed “Sevin” (a type of pesticide and it is very strong so be careful) in the grass and that evenutally got rid of them. It can be a slow process. I still see a few patches of moth eggs here and there so when I do, I scrub it off immediately (hot soapy water) and spray sevin or put sealer on it. Good luck. I know it is repulsive but it will eventually go away.

    Glad to know it gets better! There were so many eggs on the play set and house. It took us hours over the last few days to clean them all off. This AM, there were a few more egg sacks, but only about 10 or so. I guess we’ll just have to keep up with it until the moths die. I read they should die off around September (fingers crossed). Being in FL it doesn’t get really cold here for a while, but hopefully if we keep up with it, we can keep them at bay. Did you have to put anything in your yard to prevent the eggs that you removed from becoming caterpillars? Did the moth eggs come back the next year or was this a one year thing? What kind of sealant did you use on the play set and do you have to reapply it yearly? Sorry for all the questions. I am really hoping to fix this and fast!
