Combined with getting the best mosquito killer possible, Neem oil is an agent which acts as a mosquito repellent, and that is suitable for use indoors. The American Mosquito Control Association did a study in which they mixed neem oil with an equal amount of coconut oil and found that the two together were suitable for keeping mosquitoes away. The oil is a powerful anti-fungal, antibacterial and anti-viral, and it can be used not only in the home but also on your skin. The smell is good for warding off insects, and coconut oil is good for your skin as well, so when you rub the oil on your skin, you get a nice-smelling lotion that will smooth your skin, and you also enjoy the benefits of the oil warding off mosquitoes. The mosquito-deterring effect will last for about eight hours.
