Do whiteflies overwinter?
I'm located in central NJ. This is the first year I've ever had a problem with whitefly. I'm growing cukes, tomatoes and eggplant in containers on my patio. They're all infested. I've been spraying with Safer's soap and today I used neem oil. It slows them down but they're still pretty bad. My tomatoes are about done for anyway, since they got early blight (again), so I'm planning on taking them out in a few days. I'll be changing the soil mix on all the containers before next season. Do I have to worry about them coming back next year?
