Abstract: A yellow jacket bait bottle is provided and designed for effective and safe extermination of yellow jacket populations. The device comprises a cylindrical container with a hollow interior, accessible through a tamper-resistant lid featuring a hinge and flange for easy opening and closing. A plurality of access holes around the container's perimeter allows yellow jackets to enter, collect poisoned bait, and exit freely. The bait bottle includes a central hole in the lid for a flexible loop, enabling the device to be hung in various locations. The method involves placing a pesticide-laced attractant inside the container, hanging the bait bottle, and allowing yellow jackets to transport the bait back to their nest, thereby eliminating larvae and reducing the population.
