The best mixture we have found, for both yard work and mining in the
field is this one:
per one ounce grapeseed oil add 8 drops lavender oil 4 drops rosemary
oil 4 drops citronella oil
This is good to repel ALL biting insects, and has the added value of
being good for your skin. Please be certain to use essential oils
when you make your “bug juice”, and NOT alcohol extracts…
