Yes, Bifen IT can be used in a hose end sprayer. You will use 1 fl. oz. of solution and 5.5 ml of Nyguard IGR per gallon of water. You will put the concentrate directly into the cannister, and the tube will automatically use how much you have on the dial. It will disperse with each gallon that comes through the hose. You will need to be as accurate as possible when using this method. Please let us know if you have any additional questions.
When doing a soil barrier treatment for termites, it is important to treat directly against the structure on all sides of the house as close as possible. Against the foundation of the home, dig a 6 x 6 trench around the entire perimeter. Where carports and concrete patios are existing, you will drill 18-24 inch holes 2-3 inches off the foundation wall 10-12 inches apart. This will ensure the soil under that concrete slab is protecting the actual house foundation. Please read our on How To Perform A Termite Treatment Article for more detailed instructions and recommendations.
While Bifen IT is labeled for termites and will last up to 5 years in the soil, we would recommend using Termidor SC or Dominion 2L for termite soil barrier treatments. Termidor SC bonds to the soil after 24 hours and will last 10 years and Dominion 2L will last for 7 years.
