Mice and rats can learn to identify and avoid toxic baits ; this tendency is known as “bait shyness.” To avoid bait shyness, it may be necessary to prebait (offering rodents similar but non toxic bait prior to applying the toxic bait) an area prior to using toxic baits”, states Utah State University. This residential rat poison utilises the multi-feed active ingredient Difenacoum. This is an anticoagulant designed to clot blood and spur death.

Number of bait stations must directly correlate to the degree of rat infestation on your farm: the larger the rat population, the more baits you need. It has new active capsulation technology where the active ingredient uses a coat of continuous polymeric material film. When the mice intake the rat bait, they unwittingly ingest alphacholarlose with no taste or initial side effects. The shell remains intact when eaten and then dissolves in the bloodstream and emits a lethal dose. The creatures are then immobilized and go into a coma. The alphachloralose stays in the bloodstream and does not affect secondary predators. Gfeller, Roger W.; Shawn P. Messonnier (2004). Small Animal Toxicology and Poisonings. Mosby. pp.321–326.

Retrieved 24 December 2008. Although this rodenticide [cholecalciferol] was introduced with claims that it was less toxic to nontarget species than to rodents, clinical experience has shown that rodenticides containing cholecalciferol are a significant health threat to dogs and cats. Cholecalciferol produces hypercalcemia, which results in systemic calcification of soft tissue, leading to kidney failure, cardiac abnormalities, hypertension, CNS depression and GI upset. Signs generally develop within 18-36 hours of ingestion and can include depression, anorexia, polyuria and polydipsia. As serum calcium concentrations increase, clinical signs become more severe. ...GI smooth muscle excitability decreases and is manifest by anorexia, vomiting and constipation. ...Loss of renal concentrating ability is a direct result of hypercalcemia. As hypercalcemia persists, mineralization of the kidneys results in progressive renal insufficiency." [17]

Poison dosage has less to do with how much bait to put out and more to do with how much a rat has to eat before succumbing to the poison. How much rat poison to use depends on whether the poison is fast- or slow-acting. The Ruby Whole Grain is one of the best-selling rodent solutions on the market. It contains irresistible aniseed and premium whole-grain wheat to attract more rodents with fewer grains. However, its lower potency, based on the use of Difenacoum, means that you may need more grains to handle larger rat infestations. It’s an excellent solution for dealing with a mice infestation and reducing the risk of harm to domestic animals, farm life, and children.

What is the Best Rat Poison?

The active ingredient is much less toxic than other active ingredients in rat poison, making it safer. However, you may need multiple feeds to hit a lethal dose for a large infestation of rats. Fish-flavored nuggets attract and keep rats nibbling; suitable for large- and small-scale infestations Unfortunately not anymore, there used to be a product that was odourless but it is no longer used in rat poison. The odour in rat poison is what attracts the rats, it’s strong garlic-like smell from the phosphine. Can you create a DIY rat poison? This has led environmental researchers to conclude that low strength, long duration rodenticides (generally first generation anticoagulants) are the best balance between maximum effect and minimum risk.
