Bifen IT cannot be used on areas that will be used for grazing by animals. Please let us know what you will be treating so that we can offer a product that will fit your needs.
We do not recommend mixing together two pyrethroids such as Bifen IT and a permethrin product. These products are too similar, and you could create a repellency issue rather than allowing insects to actually contact the treated areas. If you want to add something to Bifen IT for faster intiial knockdown, then we suggest a pyrethrin and/or PBO product such as ExciteR Insecticide.
