AI is most strongly guessing stink bug. Do you have those?

Yes, I also got stink bugs. Moths and green lacewings are other possibilities.

Sounds like I should get out the vacuum...

Green lacewings are benefitial insects, and their eggs are fairly distictive. The eggs are individual and at the end of a short hairlike structure, rather than being glued to the surface and together.

I live in a different area and cannot really help with the photo egg id though.

I would be curious and also not want them in my house. I think I would remove the screen and put it outside until they hatch and just keep the window closed.

Don't vacuum them! If you do, they'll hatch inside your vacuum and be all over the house.

"Don't vacuum them! If you do, they'll hatch inside your vacuum and be all over the house."

ACK! I didn't even think of that! Well, I didn't vaccuum anyway, but I'll have to remember that..

I ended up taking a wet paper towel and rubbing them off the screen, they were sticky so I had to wipe residue off the window, too. I didn't check back to this post until this morning and the deed was already done, I probably would have left them if maybe they were daddy longlegs. Although, I did see some stinkbugs hanging out on the other screens, so I really don't know what it was. Good tip to take the screens out while they hatch, I didn't think of that, either.

The eggs are on the OUTSIDE of the screen (the daddy long legs was outside). These arachnids are not actually ”spiders.” and they are harmless to humans. They eat aphids and fungi — that’s a good thing.

Please let them hatch and be on their way. They are not interested getting indoors.

Also (for the most part) when you vacuum up insects, they are going to be smothered by the mechanical and air dynamics of the process. Their breathing aperatus with become clogged with fine dust particles because of all the turbulance. They will likely sustain a good bruising.

But, again, there is absolutely no reason that I can see to disturb or kill them. They will soon be on their way, into the garden or woods. Enjoy nature.

I think you can rule out chickens :-). Although a newly laying pullet's eggs are pretty small.

Here's what lacewing eggs look like - the larvae are beneficial - they eat all kinds of tiny bugs - like aphids...

And many of the images I saw of stinkbug eggs show a much smaller number, with them being larger than the OP and flattened on top. The OP makes me think of armyworms - a moth larvae, whose eggs are laid in big masses like that, but on leaves.

P.S. I squirt some boric acid/roach powder or diatomaceous earth into the vacuum bag to help with dispatching any live insects that get sucked up.

carolb, it is not necessary and if the vac bag, cannister is in the room where you are working, you may end up inhaling the diatomaceous material. It is essentially glass or perhaps shell — that means that it will remain in your lung and will not break down. If you do this frequently, I think you’d run a risk of something equivalent to silicosis.

Diatomaceous earth is diatoms - mostly silicon dioxide, but I used boric acid much more often. That was in the past however, I haven't done so in years.
