svb is a nasty bug. Sorry about your squash. I took a bit of advise I picked up here and this year planted my summer squash a little later for my area about June 10th from seed. It seems the moths stop laying their eggs here in the middle of June, so by the the time the plants emerge they miss most of the bugs. Well, at least it has worked for me. The only problem I,ve had this year is finding enough neighbors to eat my excess production. In past years I've tried insecticides and row covers with limited success. I managed to get all the squash I wanted before the borers got the plants but for me it's a pride thing. Can't stand to let them beat me.

I'm going to try the late planting next year. It is so disheartening to see your plants die from those stinking bugs....I think I will wait too...although I did get some nice squash before they bit the dust.

Hmm...did you lose the plants to the vine borer or to the squash beetle? If its the beetles, just check the plants daily and squish the larvae, eggs, and beetles. For the SVB use row covers, plant later, pray a lot....

Another advantage of the later planting is that the vines literally seem to leap out of the ground.

It was not the SVB, it was the squash beetles.

I've used row covers on both cukes and zucchini with great success. I put them on right after planting the seed, weighting down the edges with stones or soil and leaving enough slack so the plants can push them up. They don't come off until the plants start flowering (it was July 5th this year). By that time the squash bugs and borers have given up and left and I'm harvesting more cukes and squash than I really need.
Incidentally, I thinned to 5 zucchini but of them, three are producing and the other two just providing male blossom. So you need to plant more than you think you need.

And / or spray the leaves with Rotenone for squash bugs. After the eggs hatch the larvae begin to feed, ingest the Rote and they die.

Same for SVB's, but spray the stems instead.

My method for controlling squash bugs is simple. Squash bugs don't like moisture so if you give the plants a good spritz with your water hose every day or so for awhile they'll come to the top of the plants to dry off. At that point it's very easy to knock them off into a cup of soapy water. Or, handpick them and drop them in the water. If you're squeamish about touching them, wear gloves. They're pretty slow so they're easy to get.

If you do this early in the season you can make a significant dent in the population before they start to reproduce. I've killed literally hundreds of squash bugs this season thus far. I still check for populations every few days.
