Active ingredient vs formulation explained The active ingredient is the core of a pesticide. It is the component that kills, repels, or controls pests. The formulation is the blend of the active ingredient with other ingredients that make the product stable, safe, and ready to use. This also determines how the product can be applied, whether as a spray, bait, or mist. At ENTOM we always match the right active ingredient with the right formulation for safe and effective results. #AskSirElmer #Ent
