Greetings...we have been testing a variety of natural ingredients in an effort to develop a safe and effective repellent. We have tested everything that can be purchased over the counter and a variety of formulas we have discovered in books and the internet. Our goal is to stick with natural materials that are effective for both people and animals. Any ideas would be appreciated. The one formula that we have found to be very effective contains soybean oil, geranium oil, castor oil, purified water, coconut oil, glycerin, citric acid, lecithin, sodium bicarbonate, benzoic acid in a blend of essential oils of wintergreen, citronella, cedarwood, peppermint, and lemongrass.
Any suggestions would be welcomed.
