Parakito mosquito bands are an all-natural mosquito protection product that uses our patented DiffuControl-System™ technology. This system regulates the 6 essential oils used in the Parakito pellets, enabling a sustained release and continuous round-the-clock protection for up to 15 days per pellet. Parakito is safe for everybody to use, including pregnant women and babies. The wristband pellets do not come into contact with the skin, so there is little chance of irritation.
