First two things I noticed? Lots of BUGS in your sticky traps so they must be effective.
And AWESOME re-use of cat litter tubs to hold up your plastic sheeting! I give ours to Beau who fills them with spent vehicle oil and then when he orders recycled blacktop for the driveway (one full mile of it!) he moves it around with the skid steer them sprays oil on top to seal it. It lasts a good while longer that way.

Traps....They do work but are not 100 percent effective. Buy them when you buy seed and get them out early. I also tried some homemade traps that did not work at all. (Did not get the color right I think!)
I think that I need to skip squash for a few seasons and see if I can get the beetles under control. There is a community garden about 1/2 a mile away and the time I visited it at least one plot was really thick with squash nymphs and probably the source of a lot of pests so I am not certain
Diana, You can drive from the county road to your house without kicking up lot of dust! I have to say that anyone with a 1 mile long blacktop driveway you should generally consider themselves successful in life! :)
