Oh boy you’re in for a battle. We’ve had squash bugs now for the second year and they are aggressive and once they’ve produced a few generations they are near impossible to get rid of. We’ve gotten to the point where we’re not going to plant any squash for a couple years because they overwinter in the soil.
Your best bet is to get the eggs off the leaves before they hatch. I like to use a piece of duct tape to pull the eggs off. If you get to it early you can stop an infestation. But if you have eggs on nearly every leaf then it’s too late. Even with heavy pesticides the cycle is hard to break. If the eggs hatch you can still kill the nymphs pretty easily with natural things like diatomaceous earth or Castile soap spray, but once the nymphs molt and turn to adult they cannot be killed without something like sevin pesticide (which will also kill beneficial bugs.)
