Has anyone ever ordered lady bugs for a garden online? I have a ton of aphids trying to eat my poor little herb garden and I do not want to spray it with anything since I use the herbs on pretty much a nightly basis and none of the nurseries in my town sell them. Also has anyone ever used lady bugs for this purpose. I am sort of skeptical about how well it works. All the reviews I read online said the lady bugs would arrive alive, but nothing about the effectiveness.
