This beauty was crafted with pets in mind - although humans can of course use it as well . Neem oil is known for repelling insects because of its, ahem, pungent smell. We mixed it with olive, sunflower and castor oil and scented the soap with tea tree and citronella essential oils. That way we can make use of the insect-repellent properties of neem oil but still create a soap with a lovely citrusy scent.
