Mites don't like cayenne any more than we do. The cayenne powder may feel like fire against your skin however it will most likely repel or kill mites. First, mix up a paste of 50g cayenne and enough water to make it into a thin mud. Then, spread the mud evenly over mite affected areas. Avoid applying the cayenne mixture anywhere near eyes, ears, nose, mouth, tongue, or sensitive or private aeas such as armpits or other similar areas. Leave the cayenne mud paste on for as long as a possible. 20 to 30 seconds should do it. Then wash it off. Warning: This may cause skin irritation.
