There are various types of rat poison on the market with various forms of action. It is important to know this information since the correct choice of poison depends on the degree of infestation.
There are three types of rat poison on the market
1. Of bromethalin. Designed for use outdoors or in commercial applications such as warehouses and plants. Bromethalin is a highly lethal, fast-acting poison that usually kills rats within a day or two after feeding, the use of these types of rodenticides are not highly recommended due to their danger.
2. Based on vitamins. Their job is to overwhelm the system with vitamin D, causing them to absorb large amounts of calcium from the blood. Too much calcium causes kidney failure, slow pulse, and muscle weakness that ultimately end in death.
3. Anticoagulant. Designed to eradicate rats by preventing blood clotting. The benefit of this type of rat poison is that rodents often return to the bait more than once. This allows them to carry food to take to their nest, providing more effective pest control. After 3 days the poison begins to take effect and they die leaving a dissected body thus avoiding the pestilence.
Remember that, regardless of the poison you choose, you must keep it out of the reach of children and pets, this with the help of Control Stations (feeders) that are boxes that prevent anyone other than rats from consuming the poison.
