I need your help. I know NOTHING about gardening, and this is my first time trying to grow anything. I started some seedlings (tomato, chives, etc) last week in egg cartons. They are growing really well, but now I notice tiny white bugs crawling around in the dirt. I bought the dirt at the hardware store. Do I have to throw this out? What do I do? I have the seedlings inside my house so I don't want bugs in there.
