I use coconut oil for everything LOL but have never tried it for ticks / mosquitoes ... it MIGHT be just you because I have gotten ticks on myself, and I am slathered in coconut oil when I go out in the woods.
I use Apple Cider Vinegar / garlic and a natural product called NIX on ticks ... I googled it but can't find it ... I think it's a local product to Ottawa ... I put three drops on her neck, the middle of her back and her butt and life is good. I repeat it every 2 weeks.
If it works for you ... AWESOME ...
