Thomas from Lexingon, Sc writes
Captain Jacks Deadbug Brew Flower and Vegetable Garden Dust is labeled for worms on winter squash. It might kill them if they ingest it but this type of pest is generally treated with a topical kill insecticide. We would recommend using Fertilome Triple Action for squash vine borers. This product is an insecticide, fungicide and miticide all in one. This can be used up until the day of harvest.
