- Safety and accessibility: Use tamper-resistant stations where children, pets, or non-target animals may access bait. Always observe storage and disposal guidelines to minimize risks.
- Feeding behavior and resistance: Some products may require multiple exposure days and can face bait shyness if not used properly. Rotate placements to maintain efficacy.
- Environmental considerations: Weather resistance and perimeters protection help maintain bait integrity in outdoor settings. Consider seasonal needs and farm layout when planning placements.
- Regulatory compliance: Follow all label directions, disposal requirements, and local pest control regulations. Use integrated pest management practices alongside bait blocks for best results.
