  • ANT BAIT STATIONS WITH ATTRACTANT VECTOR COMPARTMENT AND EASY OPENING
    Publication number: 20170245488
    Abstract: An ant bait station is formed as a stick pack having multiple compartments, wherein each of the compartments contain a bait for a target ant species, and includes a plurality of apertures to the respective compartments. Some or all of the baits may contain a pesticide, for example a borate. In at least one of the compartments containing a pesticide, the apertures are large enough to permit the target ants to enter and exit. In some embodiment a compartment contains a bait without a pesticide. This may improve performance if the non-pesticidal bait attracts ants to the trap, and the lack of pesticidal component extends the life of the attractant. The compartment containing the bait without a pesticide may have apertures that are too small to permit the ants from entering and exiting.
