Get some Deris from the garden centre. It's made from organic something or other and comes in a powder. Squirt it all over the plant to keep the bugs off.

If you want to get rid of the actual infestation first, get some soapy water (the old washing up water will do) and swish the plant upside down in the water to wash out all the whitefly. Make sure you hold on to the plant as well as the pot to stop it falling out. Squirting a mist of soapy water over the plants should keep the flies off, too.
