Get ready to fight those bugs with our Bugger Off Soap. This soap contains Mastic essential oil which is steam distilled from the resin of the mastic tree. The oil has a fresh, balsamic fragrance similar to pine. We have also added Citronella Essential oil. Citronella is a grass that mainly grows in some Asian countries and some islands of the South Pacific. It has a rich, crisp lemony scent. Citronella has been registered as a gentle, plant-based insect repellent in the United States since 1948. It has even been shown to repel dangerous Aedes aegypti mosquitoes, which are capable of spreading “dengue fever.” It’s also effective for helping to prevent body lice, head lice and flies.
