I get so frustrated trying to grow zucchini & fight the squash bugs! Tried planting later (June) & supposedly the squash bug egg laying is over ? No luck! I decided to cut some big squares out of some red plastic I had ... cut a hole in the center big enough to fit around each plant & planted the squash in the ground (had drip lines running under the rows of squash) thinking maybe the squash bugs wouldn't crawl across the plastic to the plants ( & perhaps not underneath the plastic also?), Not seen any bugs yet... but a bit early yet here for them....but I noticed the plants have grown huge & small squash on them already!!! Is this an effect of the red plastic on the plants ... seems I read once it was!?
