I have aphids and white fly attacking my chiles and violets. I have been squeezing them with my fingers. What can I use on the plants that is non-toxic to the edible habs? A white fly spray I used last year killed the plants. Haven't had any luck with insecticidal soap. I am concerned that the Jobe spikes with the insecticide in them could make my habs inedible. All the plants I carefully rooted from Florida were killed by these beasts. Karen kstober@att.com
