A composite particle comprises i) an hydrophobic particle that adheres to the cuticle of one or more species of animal infesting arthropod; and ii) at least one organic chemical compound admixed therewith, wherein the said organic chemical is capable of controlling the population of at least one animal infesting arthropod species. Experiments proved the efficacy of the particle, for example in powder form, in relation to a variety of arthropods, for example red poultry mites.

Control of arthropods in animal environments

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 &#x3bc;m 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; &#x2266;10% by weight of biologically active chemical agent; and 0.5% by weight of flow agent.
