Someone told me to plant mint in pots along the squash row and that did seem to help. I sprayed the product Messenger as well. My squash lasted longer this year. Dale in SC

Hi jerseytom - I have linked the FAQ below on controls for SVB and there are also 100's of discussions here on SVB that a search will pull up for you to review for even more tips.

Some recommend foil stem wrapping and diatomaceous earth to kill the larvae. I use some row covers and hand pollinate plus crop timing to avoid the worst times for them but their hatch dates may vary in your zone. Your local country extension office is also a good source of info on hatch dates locally and possible controls so check them out too.

Good luck.

Row cover is the way to go. You can buy the stuff at your local garden center and cooperative extension can tell you when it is safe to remove them.
Up here the SVB generally vanish around July 1st. My zucchini was planted in late May and IMMEDIATELY covered with row cover (with lots of slack so the plants can push it up). The cover came off July 5th by which time the plants had male flowers. I've been picking zukes since the 25th of July - hard to keep up with the supply. Row cover is reusable for 5 years or so if stored inside after removal.
