<p>Dispensers and methods are described for the control of insects, especially cockroaches, with prolonged residual effect, and the protection of the toxicants employed from degradation due to exposure to atmospheric conditions. The dispensers are specially constructed laminates of layers of solid polymeric materials , and may be provided in the form of adhesive strips, loops, shelters (harborage), traps, confetti or other suitable configurations. The laminates have a core layer preferably formed from a plastisol of a polymer, containing specially selected active agents from the group consisting of Chlorpyrifos*, Diazinon*, Chlordane*, Carbaryl*, Malathion*, Bioresmethrin*, and Fenchlorphos* which have been found to be active agents which not only are toxic to cockroaches but also are capable of migrating from the core layer to provide effective levels of toxicant on the surface of the dispenser and to control the release of additional toxicant to maintain a prolonged residual effect with minimum danger to the environment.</p> |
