Should Corn Cob-Based Rodent Control Products Stay on the Market?
Official title: Consultation on Cellulose (from powdered corn cobs) and its associated end-use products, Proposed Re-evaluation Decision PRVD2025-04
Health Canada reviewed cellulose rodenticides—pellets made from powdered corn cobs that kill rats and mice by disrupting their digestion. The verdict? These products are safe to keep selling, with minor label updates. They're considered a lower-risk alternative to traditional rat poisons.
Why This Matters
Got mice in your house or barn? These corn cob-based products are one of the safer options on the shelf. They're less toxic than conventional rat poisons, which matters if you have kids, pets, or wildlife nearby.
What Could Change
Six household products and one commercial product will stay registered for sale in Canada. Labels will be updated with new safety statements. No products are being banned or restricted.
Key Issues
- Should cellulose rodenticides continue to be registered in Canada?
- Are the proposed label updates sufficient to mitigate risks?
