A method of delivering a biologically active chemical agent to an arthropod pest of a bee, comprising exposing a surface of the said bee to carnauba wax particles having a volume mean diameter of at least 10 mum comprising at least one biologically active chemical agent, wherein the bee delivers the biologically active chemical agent to the arthropod pest, characterized in that the carnauba wax particles consist essentially of 89.5-99.4% by weight of carnauba wax; @10% by weight of biologically active chemical agent; and 0.5% by weight of flow agent. |
