To use, mix the FD350 Termite Control liquid with water, using a ratio of 20ml liquid concentrate per liter of water. Thus, 120ml concentrate makes 6 liters solution, 1liter concentrate makes 50 liters solution, and 1 gallon concentrate makes 50 gallons solution. This is used mostly in spraying termite infestations in outdoor areas, including termite mounds as well as termite proofing around existing structures.
