i use my wife's remedy for pests and it works phenomenally, take a 32 oz. spray bottle and add 4 or 5 drops of rosemary essential oil and spray your plants every day for a week, the rosemary does no harm to the plant and is eco-friendly and the critters scatter for the hills, works all the time and i spray my new plants twice a week with it and never have a problem. make sure you spray all the leaves top and bottom....you can get rosemary essential oil at any health food store and is only about $6 to $8 a bottle...you will be pleasantly surprised.
