How to use

Spraying Method:

  • Dilute Twenty One in water
  • Spray the diluted solution onto walls or floors in the affected area
  • The fly pheromones and attractants in Twenty One will lure the flies to the treated surfaces for fast and effective control


Painting Method:

  • Mix Twenty One into a thicker emulsion (similar to paste consistency)
  • Paint this emulsion directly onto boards
  • Hang the treated boards in the unit where flies are a problem
  • The attractants in Twenty One will help attract the flies to the painted boards, leading to quick results

Remember to follow safety guidelines and use Twenty One as directed. If you have any specific questions or need further assistance, feel free to ask us.
