I didn't do cucumbers this spring either b/c the tomatoes were too time consuming. But in the past I just put tulle (bridal veil material) over the entire plant; I attach with clothespins right before dark and took it off in the AM. The entire plant needs to be covered.
When my plants got large, and some of my tulle got holes in it, I would layer it. The moths sometimes got through one layer of tulle but then were stuck for me to smash the next morning (I loved that part). They are determined.
I didn't spray and only lost 3 cucumbers (out of 330) to worms.
It is so cool taking it off in the AM, b/c bees are waiting to get to the flowers.
The moth itself is pretty small.
