13 The body'sĪbility to maintain proper calcium levels must be overwhelmed before cholecalciferol becomes toxic. Nervous system, muscles, the gastrointestinal tract, cardiovascular system, and the kidneys. 13 Toxic doses of cholecalciferol lead to too much calcium in the blood, which can affect the central 13 Vitamin D helps the body maintain calcium balance by enhancing absorption of calcium from the gutĪnd kidneys. 12 Bromethalin is considered a single-dose rodenticide.Ĭholecalciferol was first registered as a rodenticide in the United States in 1984. The varying ability of different species to break down bromethalin mayĮxplain why it is more toxic to some animals than others. 12 The major breakdown product of bromethalin Swell, this puts pressure on the brain, and paralysis and death
Each of these pesticides works in a different way.īromethalin was first registered by the U.S. States: bromethalin, cholecalciferol, zinc phosphide, and These are currently used within the United There are a number of rodenticides that work differently thanĪnticoagulants. Multiple-dose rodenticides because this is less confusing. Generation", many sources refer to them as single-dose or Rodenticides are not allowed to be marketed to non-licensedĬlassifying anticoagulants into "first generation" or "second Or single-dose anticoagulants, are not easily excreted from theīody, and they can be stored in the liver. Interfere with other steps in Vitamin K recycling. Tightly to the enzyme that makes bloodclotting agents. Single-dose anticoagulants are more toxic because they bind more One day's feeding can deliver a toxic dose. Single-dose anticoagulants, such as brodifacoum, bromadiolone, and difethialone are more toxic. These are known as multiple-dose anticoagulants. Warfarin, chlorophacinone, and diphacinone generally require that an animal eat multiple doses of the bait over several days.
9 Which anticoagulants require more feedings to work? This led to the development of new rodenticides. Researchers found that a fungus had converted aĬhemical that occurs naturally in the clover to a more toxic chemical. In moldy sweet clover that had made a herd of cattle sick.
Warfarin was the first anticoagulant rodenticide. Environmental Protection Agency, Office of Pesticide Programs, Label Review Manual, Chapter 7: ACUTE TOXICITY CLASSIFICATION - RODENTICIDESĬlassification categories were modeled after the U.S. Will run out and internal bleeding may begin. Our bodies store an extra supply, but if we are exposed to enough anticoagulant, the supply Anticoagulants stop this enzymeįrom doing its job. Make the blood clotting agents that protect us from bleeding too much. Our livers make a special enzyme that allows our bodies to recycle Vitamin K. 3,5,7 Bromethalin is moderately toxic for dermal exposure. 6 Strychnine, cholecalciferol, and zinc phosphide are relatively low in The exceptions include warfarin, which is low in toxicity Inhaled and when they come into contact with skin. 3,4,5,6 Most rodenticides are also toxic when How toxic are rodenticides?Īll rodenticides can be toxic when eaten. This fact sheet will discuss zinc phosphide, bromethalin, cholecalciferol, and strychnine. There are a number of rodenticides that are not anticoagulants, and these work in different ways. Bromadiolone, chlorophacinone, difethialone, brodifacoum, and warfarin are all anticoagulants. Many rodenticides stop normal blood clotting these are calledĪnticoagulants. Grouped together according to how they work. There are many different active ingredients registered as rodenticides in the United States. How many kinds of rodenticides are there? See the information below about what you can do to reduce risks. For ways to prevent exposures to children, pets, and wildlife, Tamper-resistant bait stations make it even more difficult for accidents to happen. 2 These may be attractive to children and pets, so they should never be used or stored within Baits used inĪgriculture and natural areas may contain ground meat, vegetables, May include fish oil, molasses or peanut butter. Rodenticides are usuallyįormulated as baits, which are designed to attract animals. Rodenticides have the same effect when eatenīy any mammal. Rodents, humans, dogs and cats are all mammals, so our bodies work
They can damageĬrops, violate housing codes, transmit disease, and in some cases In nature, they may sometimes require control. Only rats and mice, but also squirrels, woodchucks, chipmunks, porcupines, Rodenticides are pesticides that kill rodents.
