Combine 1 tablespoon of Dr. Bronner's castile soap -- I prefer peppermint -- with water in a clean spray bottle.
Invert it gently several times to mix but DON'T SHAKE IT.
Next, spray the insecticidal soap spray to your plants in a heavy coating.
Let air dry.
You have to saturate the bugs in order to eliminate them so don’t be shy!
Then I spray again.
Wipe dry.
