How rodenticides work

Rodenticides are toxic to rodents in so many ways. In addition, they can harm human beings and pets as well. Rodenticides usually have two types of ingredients. They can be coagulants or anticoagulants. Active ingredients in rodenticides that are anticoagulants include diphacinone, warfarin, and bromadiolone. These disrupt the blood’s ability to clot, leading to internal bleeding and rodents suffocate from internal hemorrhages. On the other hand, products with non-anticoagulant affect the nervous system. Others can increase the levels of calcium in the blood, leading to kidney, liver, or heart failure. They usually contain ingredients like bromethalin or cholecalciferol.

Rat poison ingredients are rodenticides and are categorized into the first-generation and second generation. They usually contain Bromadiolone, Diphacinone, Brodifacoum, etc… First-generation poison kills rodents slowly. Also, there are several days of feeding required. This type of poison has a cumulative effect, so the rodents do not die instantly, but instead after a few days. For good results, the rats should eat the poisonous bait repeatedly.
