1. An insecticide composition comprising:
- approximately 0.05% to 10% by weight of at least one active agent selected from the group consisting of rotenone, reduced rotenone and a mixture of rotenone and reduced rotenone, wherein said active agent is at least 90% pure;
microscopic polymer spherules, wherein said active agent is adsorbed to the surface of said spherules and wherein said polymer is selected from the group consisting of polysaccharide, polyamide, polyalkylene, polyarylalkylene, polyalkylidene and polysiloxane; and
approximately 80 to 95.5% of a carrier or diluent.

Abstract
Insecticide composition, especially a pediculicide, comprising as active agent, rotenone or reduced rotenone. The composition is characterized in that said agent is bound to small polymer spherules. The retonone and/or reduced is preferably at least 90% pure. The composition may be in the form of a suspension, an emulsion, a powder, a paste, a cream or a foam and the like. The novel composition is useful in the treatment of parasites in both humans and animals.
