Rats enter homes through toilets and broken drains. Parasites and disease are carried by rats that are transmitted to other animals and to humans. Rat poison is used to kill a variety of vermin that infest homes, buildings, gardens and other locales. There are a number of ingredients of rat poison.
Food Source and Filler
According to the ingredient list in d-Con rat poison, wheat bran and kaolin are listed first, denoting these two ingredients make up the bulk of the recipe. Wheat bran is a food source for rats and kaolin is a filler. Kaolin is one of Georgia’s largest natural resources. It is a white clay rock made up of khandite minerals. Kaolin is commonly used as filler in plastics and rubber. Kaolin adds bulk to the bait pellets.
Anticoagulants are another common ingredient in rat poison. Included among the anticoagulants used as ingredients in rat poison are hydroxycoumarins and indandiones. These chemicals block the absorption of vitamin K in the body. The net effect of this process is to inhibit the production of necessary blood clotting factors in the bloodstream. Death occurs after steady ingestion of these elements over the course of a week or even longer.
Sweetener and Solvent
Sucrose is sugar made from sugar cane or sugar beets. The two ingredients of sucrose are glucose and fructose. Rats will eat sweet foods found inside kitchen cabinets. Propylene glycol is a clear, odorless, oily liquid that is derived from petroleum. This solvent easily penetrates the skin. Propylene glycol works to retain moisture content and prevent drying out. It is used in deodorant, antifreeze, floor wax, shampoos and dozens of household items.
Flavor Enhancer and Colorant
Sodium glutamate is an acid isolated from vegetable sources, including wheat gluten, soybeans and casein. It is used to enhance the flavor of foods, according to Cornell College: The Monosodium Glutamate Story. The colorant in rat bait is pigment Green 7(also called as Phthalocyanine Green G, CAS No. 1328-53-6).
Vitamin D, D1 and D2 are used as ingredients in rat poison. In small doses, these vitamins are beneficial to human beings. However, even small amounts cause death in rats. Death occurs through what is known as hypervitaminosis or vitamin poisoning. A large dose of one or another of these types of vitamin D is necessary to cause harm to a human being. A dose of vitamin D, D1 or D2 causes death in a rat within about 36 hours.
