Try a leaf spray of sea weed fertiliser and keep the water up to the plants. whitefly usually attack water stressed plants.

Thats cheating!
Environmentally it may use too much energy?
Here, activated charcoal for Hort. use (Barmac's "Pick Up") is $150 for about 5K !!
The supermarket sells 3.5K of BBQ charcoal ("Redhead") for AUD$7. It is made from coconuts, I think, comes from Malaysia, and is easy to break up with a brick.
Best Energies can make low quality activated charcoal at about 500C by adding water and air to the pyrolysis mix. Stephen Joseph says it does hold more water in the soil/potting mix.
Herbs don't always need lots of water especially Mediterranean ones like rosemary, thyme, lavender etc
