dimu borgir-squash bugs are horrible…you can wrap the bases of summer or winter squash plants with tin foil so the bugs can’t bore into the vine and have seen mixed results with that. You can also look for the ‘sawdust sign’ and if you catch the borer soon enough you can twist wire up into the plant stem and kill the bug that way. Lot of work when you grow dozens of plants, though! I have used diatomaceous earth and it seems to help some with them.
