Apply Honey Bandit or Honey Robber® to the felt underside of the fume board in the shape of an "X" or "S". Place fume board on top of the upper super with corners of frames exposed for airflow. Removal time will depend on temperature and humidity. The black corrugated top works to raise the temperature by 10-15°F which increases the vaporization of the Honey Robber® making it work better and faster. Honey Robber® sold separately.
