Control of termites comprises termiticide in moisture-sensitive polymer matrix providing slow controlled release

摘要

A product for destroying termites comprises a termiticide incorporated in a solid matrix comprising a meltable hydrophilic polymer binder which is sensitive to ambient moisture and provides initial rapid release of the termiticide followed by slow controlled release over a long period. Independent claims are also included for: (1) the production of the product by melting the binder, mixing it with 1-50 (preferably 20-50) wt. % of the termiticide, and shaping the mixture by application of heat and pressure; (2) a process for implantation (sic) of the product at a location in a site to be protected, comprising humidifying the location and placing the product in the location.
