ULD BP-100 Contact Insecticide II is a liquid, oil-based fogging concentrate built around synergized pyrethrins paired with a piperonyl butoxide booster. The formulation is designed for premise use, including livestock facilities, grain and food-handling operations, and commercial or residential structures. It can be applied full strength or diluted, and it is compatible with a range of fogging, misting, and spraying equipment used for crack-and-crevice, space, or contact treatments. Each container holds the ready-to-use or dilutable concentrate with no additional assembly needed before application. The product carries EPA registration for insecticide use and is labeled for application in federally inspected meat and poultry plants. Handlers should follow label directions for dilution ratios, application equipment, and re-entry timing after treatment.
