Neem oil is generally safe to apply to the skin. However, it is very potent, so it may be a good idea to test it on a small patch of skin before applying it more extensively. To perform a patch test, mix a couple of drops of neem oil with water or liquid soap. Neem oil takes time to work. It might be two days or more before you see a reduction in damage or fewer live insects. You may need to reapply your neem product every three or four days, especially after rain, to completely get rid of your target pests.
