Rodenticides are chemicals made and sold for the purpose of killing rodents. While commonly referred to as " rat poison ", rodenticides are also used to kill mice , woodchucks , chipmunks , porcupines , nutria , beavers , [ 1 ] and voles .
Bromethalin was discovered in the early 1980s through an approach to find replacement rodenticides for first-generation anticoagulants, especially to be useful against rodents that had become resistant to Warfarin-type anticoagulant poisons.
Norbormide (Raticate, Shoxin) is a toxic compound used as a rodenticide.It has several mechanisms of action, acting as a vasoconstrictor and calcium channel blocker, [1] but is selectively toxic to rats and has relatively low toxicity to other species, due to a species specific action of opening the permeability transition pores in rat mitochondria.
Similar to other rodenticides, the preparation requires 3–7 days to be effective. Rather than killing rodents through internal haemorrhaging as anticoagulants do, [9] PCC affects a rodent’s digestive system, causing acute dehydration due to its extremely absorptive nature (corn cob has been used in applications such as oil spills in water bodies, seed drying and de-icing).

Diphenadione is a vitamin K antagonist that has anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and other rodents. The chemical compound is an anti-coagulant with active half-life longer than warfarin and other synthetic 1,3-indandione anticoagulants.
d-CON is an America brand of rodent control products, which is distributed and owned in the United States by the UK-based consumer goods company Reckitt. The brand includes traps and baits for use around the home for trapping and killing some rats and mice. As of 2015, bait products use first-generation vitamin K anticoagulants as poison.
Warning label on a tube of rat poison containing bromadiolone on a dike of the Scheldt river in Steendorp, Belgium. Bromadiolone is a potent anticoagulant rodenticide.It is a second-generation 4-hydroxycoumarin derivative and vitamin K antagonist, often called a "super-warfarin" for its added potency and tendency to accumulate in the liver of the poisoned organism.
Coumatetralyl is commonly used with grains and other cereals as a rodent poison in conjunction with a tracking powder to monitor feeding activity in a particular area. Tracking powder also clings to fur, which allows more poison to be ingested from grooming.
