Squash Bugs

I have identified the pests that are attacking my zucchini and volunteer pumpkin plants. I've seen all the stages, but didn't realize they were all related. Here's some info about the evil Squash Bug:

Sadly, from what I've read, it seems the best defense may be a good offense. That is, I have to go out hunting and squashing. Yuck!
