Abstract
Abstract @ A method and phase changing composition with an in situ insecticide for the killing of insects on animals over an extended period of time. The phase changing composition with an in situ insecticide comprises a film-former such as hydroxypropyl cellulose, ethyl cellulose and methyl cellulose, an insecticide and a rapidly evaporating solvent such as volatile alcohol. When the phase changing insecticide composition is applied to an animal, it leaves a liquid bead on the animal which penetrates and encapsulates a portion of the animal's body hairs. As the liquid solvent in the liquid bead evaporates, it forms a dry-to-the-touch gel bead that contains the in situ insecticide which is released from the gel bead over and extended period of time.
