Zinc phosphide is a highly toxic rodenticide used to control gophers, moles, and other burrowing pests. It is commonly sold as pellet or grain baits placed in underground burrows. When swallowed, zinc phosphide reacts with stomach acid to release phosphine gas, which is rapidly absorbed and can cause severe, life-threatening poisoning in dogs, cats, and wildlife.

Pets are most often exposed by digging up and eating bait pellets, consuming a poisoned rodent, or getting into stored product. Even small amounts can be lethal, and clinical signs may develop within minutes to a few hours. Because vomiting can release phosphine gas and expose both the pet and owner, do not induce vomiting at home unless a veterinarian or poison control professional tells you to.

Prevention is essential: avoid using zinc phosphide baits in areas pets can access, store all pesticides in locked cabinets, supervise pets outdoors in treated areas, and consider professional pest control or pet-safe exclusion methods. If you suspect any exposure, seek emergency veterinary care immediately and bring the product label.
