I can't remember the source publication, but a mainstream health journal like the New England Journal of Medicine or something, published an article maybe three years ago on a study that found lemon eucalyptus to be the most effective herbal insect repellent. I did then buy some for body spritzes/room sprays (natural insect repellent) which are easy t make with a little polysorbate 20, but will now most definitely try in a soap!! Thanks for the information.... ALSO, I have to check out whether it's a safe e.o. in soaps for dogs.
A couple of posts mentioned lemongrass. I saw it listed as the main ingredient in a natural bedbug repellent. Has anyone heard about it? Luckily, we've so far escaped the epidemic, maybe because our place constantly smells like essential oils....mercy.
Happy and merry errrybody.
