They are about the size of pinheads, so I haven't been able to get a decent photo. I think they're moth eggs, though, as I found a photo online of moth eggs on a clothes line and they look identical to what I have seen on mine and the clothes. Gross, but not as scary as spider eggs would be! It took me awhile to find anything, but I really think that's what they are.

I was pretty sure they were eggs, and we have no trees in the backyard, so I knew it wasn't anything like that. I'll just have to keep an eye on things!

Any suggestions on how to keep them away? I don't think moth balls would really work outside, and I think they'd mostly keep the dogs from going out in the yard, hahaha.

Here's the photo I somehow came across!
