seriously awesome advice! apparently I missed some eggs and I went out to look for wilting leaves. I found a few. and I found the borers that were doing the damage! they were still tiny but I got them! and I got some with bt as well. I forgot that before I learned the wilting leaf trick on here, I put some BT into one of the stems that looked like there was a hole there and when I inspected it earlier, there was a dead one in there, yeah! it works!!!
hopefully this is all of them now, but I haven't really seen any on my summer squash yet. I'll keep looking though!
but seriously guys, THANK YOU!
