GREEN LIVINGPlant oils are alternative to DEET insecticides
Dear EarthTalk: I can't seem to find any natural bug repellents that really work so I end up using the harsh, chemical varieties. Are there any really effective bug repellants that aren't chemically based, or other strategies we can use to keep bugs at bay?

While the industry standard insect repellents rely on the insecticide DEET (N,N-Diethyl-meta-toluamide) to keep bugs at bay, many environmental and public health advocates worry that regular long-term exposure to even small amounts of the chemical can negatively affect the human nervous system.
