Bifen is not formulated to be used in any type of fogger, neither thermal or ULV. Using a product that is not meant to get broken down into that level of application, jeapordizes the quality of the product and its ability to perform appropriately, as well as can harm your fogger. Bifen should only be used in a unit that is a true sprayer. You would need to use a water based fogging concentrate in your ULV unit. You would not have to wear a respirator when spraying Bifen indoors or out but you could wear something similar to a painters mask to help protect the nose and mouth from any drift or back spray. If you were using an appropriate fogging concentrate in your ULV fogger in an indoor area you would want to use a respirator in those areas. Please let us know if you have any other questions.
