I was out in my pumpkin patch last night, it's about 30x40 and noticed clusters of red/brown eggs (maybe eight-ten eggs) in each cluster on the underside of the leaves. I squished all of the ones that I could find... but I haven't seen any adults. Is this characterisitic of squash bug or squash vine borer? I'm trying to gauge how serious this is... and if I have to break my organic rule of thumb and spray sevin. I'm setting tons of pumpkins, and would hate to lose them all at this point.

Any help or feedback is appreciated!
