Snail bait is a type of pesticide used to control gastropod pests, specifically slugs and snails, which damage crops or other valued plants by feeding on them. It is also known as molluscicide, snail pellets, or slug pellets. Snail bait is formulated in chewable pellets that are flavored with molasses, apple, and bran to attract snails and slugs. The toxic substance found in snail bait is a compound called metaldehyde, which is highly toxic and even small amounts are enough to cause poisoning in dogs. Symptoms of snail bait poisoning in dogs include vomiting, diarrhea, tremors, seizures, and even death. There are several types of chemicals that can be employed as a molluscicide, including metal salts such as iron(III) phosphate, aluminium sulfate, and ferric sodium EDTA, metaldehyde, niclosamide, and acetylcholinesterase inhibitors. Some of these chemicals are relatively non-toxic and are approved for use in organic gardening, while others are highly toxic to other animals and humans and act as contact poison.
