I wouldn't sell it to the public either. This would be for personal family/friend use onlyI wouldn't get involved in selling something like that without some serious thought and research. I'm sure there are laws that pertain to formulating and making claims about products with pesticidal properties. Even if you are on the right side of the law, you are a very small business. Ticks carry serious diseases that in some cases affect people for months or years. I don't know if you would want someone to be a user of your product when they contract something like that.
i believe rose geranium essential oil in particular is good at repelling ticks. you may need to research if a specific geranium is needed though. i thought i heard something about the geranium bourbon being good but it looks like others use rose geranium. sorry, don't have the latin names handy.Has anyone made solid soap that will repeal ticks, etc? What ingredients do you suggest? Thanks!
