Everything I've found says that squash bug eggs are yellow, yellow-brown, or reddish colored though. These are gray/silver. Squash bug eggs also are somewhat oval shaped, while these appear to be practically perfectly round. They do look similar, but I don't know. I haven't seen any squash bugs or stink bugs out back either. Of course, that doesn't mean there aren't any or that these aren't squash or stink bug eggs. I'm going to try to find a magnifying glass tomorrow and see if I can get a better look.
I don't know then cuz I had a squash bug issue earlier this season and they were everywhere. So if you don't see any I would focus on another bug. I'm all for the pruning and seeing what happens club
