What is Snail Bait?
Snail bait (metaldehyde) is severely toxic to cats and dogs, causing tremors and seizures within hours. Call a vet immediately — it moves fast.
Also known as: metaldehyde, slug bait, snail pellets, molluscicide.
Symptoms to Watch For
🐕 In Dogs
- Anxiety, panting, and drooling within 1–3 hours
- Muscle tremors and rigidity
- Seizures that can become continuous
- Dangerously high body temperature (hyperthermia)
🐈 In Cats
- Drooling, restlessness, and disorientation
- Muscle tremors and rigidity
- Seizures
- High body temperature and rapid breathing
What to Do If Ingested
- Call a veterinarian immediately — metaldehyde poisoning escalates fast.
- Note the product name and active ingredient.
- If the dog is not yet seizing and a professional directs it, decontamination may be needed — but only under guidance.
- Begin cooling with water and a fan if the body feels hot, while getting to a clinic.
Steps apply to both cats and dogs. When in doubt, call a vet or poison hotline before acting.
When to Call the Vet Immediately
Call your veterinarian or a poison control hotline right away if you notice any of these:
- Any snail bait was eaten
- Restlessness, panting, or drooling
- Tremors or seizures
- A hot body or rapid breathing
Frequently Asked Questions
Frequently Asked Questions
How fast does snail bait affect pets?
Metaldehyde acts quickly — anxiety, drooling, and tremors usually appear within 1 to 3 hours of eating the pellets. Seizures and a dangerous rise in body temperature can follow. Because it moves fast, call a vet immediately rather than waiting to see.
Should I make my pet vomit after eating snail bait?
Only if a veterinarian or poison control tells you to, and only before seizures start. Once tremors or seizures begin, inducing vomiting risks inhaling vomit into the lungs. Call a professional first — they will decide on decontamination based on timing and symptoms.
Are there pet-safe snail and slug baits?
Iron phosphate baits are generally much less toxic to pets than metaldehyde. But always check the label — metaldehyde is the dangerous one and is still sold. If you are unsure which was eaten, bring the package to the vet.
