Yikes! I thought basil, and most strong-smelling herbs, had very few bug problems.
I'm going to try basil this year, along with summer savory, sage, dill, and catmint (supposedly similar to catnip).
Dill I've grown before; sometimes it does terrific, other times... I've heard that Black Swallowtail butterfly caterpillars like to eat dill. But that would be OK with me. I also have some clumps of chives that are years old; I suppose I should divide them.
Have you tried growing your basil in pots, instead of outside? I'll probably have to do that with my catnip or catmint if I want any for me and my cat, because my neighborhood has lots of cats. I keep my cat inside, but most of my neighbors don't...
