A waste cart may be provided. The waste cart may include a housing having a top wall and a plurality of outer walls enclosing an interior space. The interior space may include a bait stick connected and extending therein. The housing may have an entranceway providing access to the interior space. The entranceway may include a passageway having a rotatably mounted plurality of tines adapted to allow one-way access into the interior space. The top wall may be pivotably connected to the housing. The top wall may be secured by a gravity locking mechanism adapted to release the top wall under the force of gravity when the waste cart is inverted, such as when the waste cart is fixed to the inside of a inversion-dumped trash bin.
