As with the cattle, warfarin disrupts the animal’s blood clotting mechanism, and the rats die from internal bleeding a few days after eating poisoned bait. Warfarin began use in the early 1950s, but within ten years rats were showing resistance to warfarin as resistant genes spread in the rat population.

Can you become resistant to warfarin?
Warfarin resistance can be either acquired or hereditary. Possible causes of acquired resistance include enzymatic induction of warfarin metabolism by other drugs, enhanced dietary intake of vitamin K, noncompliance with therapy and hypothyroidism.
