Is there a companion crop that would discourage aphids?

Ladybugs will take care of them in the GH but I don't think you want them in the house though. Rinse the lettuce a couple of times in salt water. That will take care of your current problem. John

Here is a link that might be useful: John's Journal

You can use the insecticidal soap sprays, like Safer, which kill the aphids but is not harmful to you or your lettuce.

I fought those fiends this past winter/early spring. What I found to work the best was a combo on Neem Oil and Safer Soap. I used a garden sprayer as I had hundreds of plants but being able to pump up the pressure and spray the undersides of the leaves as well as the top worked fantastically. Took about a week to eradicate them.
