Squash vine borers.

[Ifitaintbroke]

My squash have had a habit of growing very nice and big, then, when they start producing, they die from the bottom up one leaf at a time. Believe it to be vine borders, and it happens every time I plant winter squash. Solutions?

Rotate your crops and don't plant in the same location year after year.

Good idea.

I poison them. They come out with heat. 80f and its a fight. Timing the crop helps. Bifenthrin is one of the longest lasting in the soil unless you have the energy to go out there every day or after every rain. Stay off the flowers, keep to the roots and clean the debris so they cannot hide.
