Any insecticide will work. Also, move the pots to an area where there is more wind.

I have used an old tried and true method for dealing with both white fly and aphids on about every plant you can think of. Al I do is take a spray bottle and add equal parts water and rubbing alcohol - adding a couple of drops of dishwashing liquid (NOT antibacterial). Spray away being sure to get the spray into all the cracks and crevasses. I have even gone so far as to give a plant a swift kick and spray into the air above it and the white flies drop like .... well ... flies. I don't use insecticides. This has worked for years. Usually I only get bugs on things when I have brought in new plants to my garden. If I also spray down the surface of the soil in flower pots, add an inch of sand and then spray down again I usually don't see any more bugs.again. Hope this helps.
