Strict cleanup in the fall will reduce squash bugs in the following growing season dramatically!  Squash bugs overwinter in debris from all squash relative plants and these plants should be removed right at harvest time.  Leaving vines and leaves gives squash bugs a place to hide.  For bad infestations, bagging or burning may be a smart choice of removal.  Other places such as rocks, mulch, boards and other garden debris all can encourage squash bugs to hide out till the following year.  Removing these from problem areas you had this season and giving the soil a quick turn will help dramatically.  Annual crop rotation is something to keep in mind for next years squash crops.  Plant a non-cucrubit crop in areas you planted cucurbit crops this year.
