French and Mexican marigolds tend to repel whiteflies, as do nasturtiums. Put these companion plants into your garden to keep the pests from returning! Be aware that this is a preventative measure, and not a great solution for existing infestations. Pot marigolds and calendulas are not effective repellents. Make sure to use the right variety! If you aren't sure, visit a nursery and specifically ask about companion plants that repel whiteflies. In a 32-ounce spray bottle, mix rubbing alcohol with water at a 2:5 ration. Then, add a tablespoon of liquid dish soap. Use the spray bottle to coat the leaves of plants that are at risk for whitefly infestations. If you don't overdo it, the spray shouldn't harm most plants – and it might keep the flies from putting down larvae. Consider using a natural oil spray, such as Neem oil. Earthworm castings, when added to the fertilizer bed of whitefly-infested plants, have been found to repel the flies within a matter of weeks or months. As an added bonus, these castings are a rich natural fertilizer, and they can greatly stimulate plant growth. Ask for earthworm castings at a local garden store. Spread a layer of aluminum foil or reflective plastic mulch on the ground around susceptible plants. This may make it much harder for adult whiteflies to locate host plants, which in turn can bring make them less likely to successfully lay eggs.  This step will require special water considerations. Plants surrounded by plastic mulch will need a drip irrigation system. Do not use mulch in hot weather. Too much mulch may overheat the plants.
