Jim, they get my squash every year but not before they have produced a pretty good crop, so I just try to keep planting to have some coming in. The bug is squash borer, I think the eggs are laid around the base of the plant by a little wasp looking insect black with a little red, not sure about that but I have seen this bug around the plants and assumed this is the one thats doing it. The eggs hatch out into larvae and this is what bores into the vine. I'm thinking about putting collars around the base and see if that will help. I don't use poison but I've read that you can inject seven dust into the hole where the borer went in and kill it but you know that seven dust also goes right into the squash. I mulched mine heavily last year but it didn't help.jim/se kansas said:How do you get rid of squash bugs? They tap into the stem and suck the sap out and kill the plant one stem at a time.
