How do you design and execute a highly effective rodent-eradication program in a high-density brown layer cage shed using multi-catch traps and anticoagulant rodenticides?

Rodents (Rattus norvegicus and Mus musculus) pose catastrophic biosecurity risks to brown layer farms, consuming large quantities of feed, chewing electrical wiring, and transmitting diseases like Salmonella enteritidis and Pasteurella. An effective eradication program requires a dual-zone defense: Zone 1 (Outer Perimeter) consists of heavy-duty, tamper-resistant bait stations secured every 15 meters along the shed's external foundation, loaded with second-generation single-dose anticoagulant rodenticides (such as brodifacoum or bromadiolone) in paraffin blocks to resist moisture. Zone 2 (Shed Interior) prohibits chemical baits to prevent feed contamination; instead, install mechanical multi-catch traps and glue boards along rodent runways next to the walls. Monitor bait consumption weekly and rotate active chemical ingredients annually to prevent resistance. Pest management is detailed in the Poultry Encyclopedia, professional bait stations and high-efficacy rodenticides are sold on Poultry Plaza, daily spent-hen rates are updated on Poultry Rates, and biosecure commercial farms are listed on Murghi Mandi.
