Deterring squash borer

Asked March 16, 2017, 6:35 PM EDT

Recently I read (Adrian Higgins in The Washington Post) a note about deterring squash bugs by wrapping squash stems with aluminum foil. Can you comment on this idea and offer instructions (for example, does one re-wrap as the stems grow bigger?) if this is, indeed, a good way to save the squash?

This approach is one of multiple ways to try and deter the annoying squash vine borer, but it's not foolproof. Since the egg could be layed just after the foil covering or elsewhere, a combination of approaches may be most useful.

The following link from our website on this pest explains more, and even has videos of the adult (who looks like a clear wing wasp/pollinator) to watch for:
