The Vinegar of the Four Thieves is a super-strong insect repellent. It should be diluted with water to half strength if you spray it directly on your skin. This repellent can be used many ways. Splashed on your socks or shoes will discourage ticks, chiggers, and mites. An herbal cloth kept in your pocket and rubbed on your skin every hour or so would be very beneficial during outdoor work or recreation. Or, a nightly bath with a little herbal vinegar and oil will keep it on your skin for many hours and could prove helpful for families who live in the country or while out on camping trips. It should only be used externally.
