I have had problems in my backyard herb garden for a couple of years with some type of insect that devoured basil and marigolds (often the least-touched plants). I had tried a couple other organic pest deterrents with limited success. But this year the bugs were particularly bad and made their way across the path to eat all the growing tips of a trumpet vine.
If I was going to get enough basil for our year's worth of pesto and a bloom on the trumpet vine, I needed to take action.
