Can anyone give me an idea of when squash borers first show up in north central Texas? As I understand it, once they are here you are supposed to look for eggs at the base of the plants?? And/or dust with Sevin every week? Anyone have a system of dealing with borers that has worked out? I have real doubts that I'll be able to see any tiny little eggs. I had years of growing squash with no problems, then two years ago they totally wiped out all my squash and cucumbers. Last year's weather took care of the garden. Any ideas would be appreciated.
