Metaldehyde is a common active ingredient in slug and snail baits used in gardens, lawns, and flower beds. These products are often flavored with molasses, bran, or other attractants, making them especially appealing to dogs and sometimes cats. Even a small amount of metaldehyde can be life-threatening, and signs of poisoning can appear within minutes to a few hours after ingestion.
Pets exposed to metaldehyde typically develop severe neurological and physical symptoms. Early signs may include vomiting, drooling, restlessness, and uncoordinated walking. This can rapidly progress to muscle tremors, seizures, and dangerous hyperthermia (high body temperature). Without prompt veterinary treatment, metaldehyde poisoning can lead to respiratory failure and death.
Prevention is essential if you share your home with pets. Avoid using metaldehyde-based products in areas your dog or cat can access, and store all pesticides in a locked cabinet or out of reach. Consider pet-safe alternatives such as iron phosphate baits, physical barriers like copper tape, or diatomaceous earth. If you suspect your pet has eaten slug or snail bait, seek emergency veterinary care immediately.
