Which rodenticide is also known to act as an emetic?

The correct answer is that red squill is known to act as an emetic. Red squill, which is derived from the plant found in the Mediterranean region, contains compounds that induce vomiting when ingested. This property makes it particularly interesting, as it can help to reduce the risk of rodenticide poisoning in non-target species, including pets or wildlife, if they ingest it.

In the context of rodenticides, red squill's emetic action can be seen as a beneficial mechanism. It induces vomiting, which can potentially lessen the chances of significant toxicity by expelling the toxic substance before it is absorbed in large amounts. This characteristic differentiates it from other rodenticides that do not provide a similar protective effect.

Strychnine, while also a rodenticide, is primarily a neurotoxin that causes severe muscle spasms and does not act as an emetic. Warfarin is an anticoagulant that prevents blood clotting and does not have emetic properties. Arsenic is a potent poison that affects various bodily systems and does not serve as an emetic either. Thus, red squill is unique in its ability to induce vomiting, distinguishing it as the rodenticide that also acts as an emetic
