What is rat poison called? - briefly
Rodenticide formulated to kill rats is generally referred to as “rat poison,” often marketed as anticoagulant baits containing active ingredients such as bromadiolone, brodifacoum, or difenacoum.
What is rat poison called? - in detail
The chemical agents used to eliminate rats are generally referred to as rodenticides. In commercial markets the most common label is “rat bait,” which denotes a formulation containing an active toxicant designed specifically for rodents.
Active ingredients fall into several classes:
- Anticoagulants (e.g., warfarin, bromadiolone, brodifacoum) disrupt blood clotting, leading to internal hemorrhage after ingestion.
- Metal phosphides (e.g., zinc phosphide, aluminum phosphide) release phosphine gas in the stomach, causing cellular toxicity.
- Neurotoxins (e.g., bromethalin, diphacinone) impair nervous system function, resulting in paralysis and death.
- Cholecalciferol (vitamin D3) induces hypercalcemia, leading to organ failure.
Formulations may be solid blocks, pellets, granules, or liquid concentrates, each intended for placement in bait stations or concealed locations. Regulatory agencies classify these products by toxicity level; many jurisdictions require licensing for high‑potency anticoagulants such as brodifacoum.
Safety precautions include using tamper‑resistant containers, restricting access to non‑target species, and following label instructions for dosage and disposal. Proper identification of the specific compound is essential for selecting an appropriate control strategy and complying with local pest‑management regulations.
