We power our candles with the highest-performing repellent essential oils that nature has to offer. Each 9oz candle burns for 30 hours and smells exceptional. As the candle burns, our proven blend of mosquito-fighting essential oils binds to mosquitoes' olfactory receptors, creating confusion when they are looking for human indicators (like CO2 and body odor). Think of it as a minty, mosquito forcefield.
