The RESCUE! Non-Toxic Disposable Yellow Jacket Trap Western catches all major species of yellow jackets common to western North America. The trap consists of a two-layer durable plastic bag with a scientifically designed molded plastic entry structure that prevents escape. A powerful water-soluble attractant is included; you simply add water to the trap and hang it outside. Yellow jackets are lured by the attractant scent and fly into the bag through the yellow entry structure. Once the trap is full, the top cap closes shut and the entire trap can be placed in the garbage. RESCUE!’s goal is to design, manufacture and market the safest, most effective pest control solutions available. Our products are the result of exhaustive and ongoing research and development, decades of experience and a commitment to solutions that respect the environment without sacriï¬cing results. Established in 1982, RESCUE! pest management products have never used poisons or toxicants to kill pest insects.
