Why Bait Blocks Outperform Pellet Poisons

When selecting a rodenticide, the formulation matters as much as the active ingredient. While pellet poisons are common, they pose a high risk of secondary poisoning to pets and wildlife if the dying mouse wanders outside. Bait blocks (or bromadiolone) are designed to be secured inside tamper-resistant bait stations. This forces the rodent to gnaw on the block, preventing them from carrying the poison back to your pantry or exposing children and pets to the toxin.

Always remember that poison is a secondary measure. If you do not seal the entry points around your foundation, a new colony of mice will simply move in after the current one is eradicated.
