When should a poison-bait application program for rats be started at open dumps?

Starting a poison-bait application program for rats at open dumps two weeks before abandonment is advisable for several reasons. First, addressing rodent populations proactively helps mitigate potential health risks associated with rodent-borne diseases, which can be particularly concerning in areas where food waste and refuse are present. By beginning the bait application prior to abandonment, there is an opportunity to reduce the rodent population before the area becomes less monitored and possibly more conducive to infestations.

Starting the baiting process ahead of the final abandonment allows for more effective integration of other waste management strategies, including proper sanitation measures and public awareness campaigns. This timescale provides a necessary buffer to monitor and adapt the baiting approach as needed, ensuring the bait is most effective when the facility is still in use and can support follow-up measures if necessary. Additionally, a preventive measure like this is consistent with integrated pest management practices, which aim to minimize the ecological impact while maximizing the effectiveness of pest control methods. This approach supports sustainable and healthy environment management, especially in areas with potential public health implications.
