I recently heard a caller give her recipe for mosquito repellant using orange oil and vanilla. I can't remember how much of each to use. Could someone help me?

I don't know about that one. However I rub a little liquid dishwashing soap or canola oil on my exposed skin outside in the garden or at the compost piles, and no bug whatsoever bites me anymore.

This is what you want. It is posted on the web site & the discussion forum.

Most recently a caller said she uses 2 t. vanilla and 2 t. citrus oil in 32 oz. water (more diluted than previous 8 oz. recipe).
