text: We are launching some oils before summer containing an insecticide additive, which can be used as an insect repellent. The most popular oil that some people claim is effective is Citronella, but this is not backed up by any scientific evidence I’m aware of. In the U.K., it is not legal to market citronella candles as insect repellent. Only products containing a certified insecticide can be marketed as insect repellents.
  
  In short, citronella is popular, but should be marketed as an ‘outdoor’ candle, but not as an insect repellent. If you want a repellent, wait for our oils in the coming weeks.
  
  Hope this helps.
