The sweet fermented mixture varies a little depending upon what I have at home but is essentially:
1 overripe banana and/or a can of peaches in heavy syrup
A few ounces of dark rum (tasted beforehand to insure freshness)
A bottle of dark beer (tasted beforehand to insure freshness)
A box of dark brown sugar and/0r a bottle of dark molasses
Mix the remaining ingredients together with the mashed fruit (use a container with a large open mouth for ease of getting the paintbrush in and out)Put a tight lid on and leave in the sun for a few hours to a day.
Paint a 1 foot square area on tree trunks about 3 or 4 feet off the ground, the more trees the better.
