Rose, dilute some peppermint oil & spray them. It's organic. I feel your pain. We lost a lot with these root "aphids." Will probably lose quite a bit more. I have been like you, very tempted to throw it all out & sanitize, then start over. Not sure if our trusty Widow will survive the Great Bug War of 2016. Really sad. She's been with us a long time & has taught us so much as well as given us some nice quality smoke. Damn root aphids & broad mites(spit, spit!!) I do think the peppermint oil will work; freeze & suffocate the little buggers! Had to stop & halt traffic yesterday morning after work on a major 4 lane road. A little chiuawa was running scared near the edge of the road. Almost got hit. Luckily, another woman stopped to help. Saved his little butt! Hate when owners allow their dogs to run free. Poor puppy got lost & was afraid. I got put on call tonight; looks like I won't be going in. Yippie! If I didn't need money, I wouldn't work. I mean, that's just me. I'm sure most people love going to work! I just wanna get high by the beach....
