I have been reading on Companion Planting and found this regarding squash borer:

RADISH: Plant radishes with your squash plants. Radishes may protect them from squash borers. Anything that will help prevent this is worth a try. Planting them around corn and letting them go to seed will help fight corn borers.

Good luck with your squash. In 2008 I was attack by squash bugs that in turn ended up on cucumber and melons. Found this info on companion plants to deter these...I will be trying this!
CATNIP: Deters flea beetles, aphids, Japanese beetles, squash bugs, ants and weevils. Use sprigs of mint anywhere in the house you want deter mice and ants. Smells good and very safe.

DILL: Improves growth and health of cabbage. Do not plant near carrots. Best friend for lettuce. Attracts hoverflies and predatory wasps. Repels aphids and spider mites to some degree. Also may repel the dreaded squash bug! Scatter some good size dill leaves on plants that are suspect to squash bugs, like squash plants.

LEMON BALM: Sprinkle throughout the garden in an herbal powder mixture to deter many bugs. Lemon balm has citronella compounds that make this work: crush and rub the leaves on your skin to keep mosquitoes away. Use to ward off squash bugs.

Hope you find something that works!

Don't forget to practice crop rotation with squash too. I was hit bad by the borers last year so I'm planting a solid stemmed variety this year. Also, I'm planting the squash in succession so that once one plant bites the dust i'll have another to replace it.

Oh yes I have the bug.Living in Montana I have a longer wait than a lot of you .Thankfully I have a greenhouse so I can start earlier.I ordered my onion sets and seeds from Burpee yesterday.
Last year I put a raised bed on one side of my greehouse and grew my peppers in there and it worked great,so this year I am doing the same on the other side for my tomatoes.

Thank you Peggy! That was a lot of good info. I will try that. I don't like radishes but I will try it to get my squash.

The squash vine borer usually lays it eggs in July.

So two possible solutions to the squash vine borer attack:

1. Delay the planting of your summer squash to miss the feeding larvae.

2. Plant early varieties of squash. Early varieties will be large enough to withstand the attack.

Baby blue and butternut squash are nearly resistant to the borer.

Make sure to thoroughly clean up at the end of the season to keep the borer from overwintering.

Thank you Stephen.

The pepper "trick" that works for me is to grow them in containers. This give them more of the heat they love and I can better control water drainage and fertilization. I would think that heat would not be an issue in your zone. Maybe you need a spot with better drainage? They really do like good drainage and do better on the dry side.
