Bifen IT is mixed at 0.5-1 fl oz per gallon of water per 1,000 sq ft. It will provide a 30 day outdoor residual and a 90 day crack and crevice residual indoors. When mixed with water, the finished solution should be applied within 24 hrs. Please store in original container away from extreme temperatures. It will have a 3 year shelf life from the date of purchase.
