Title: Microsoft Word - Anticoagulant Rodenticides Guideline (e.g. Bromethalin and strychnine are neural toxicants. This second type of anticoagulant kills rodents in a single serving dose rather than over time. Another cause of anticoagulant poisoning in dogs is the accidental ingestion of medication. This is because they sample the food that they take by consuming it in small samples, if it’s not poisonous, they continue feeding on it. - Pesticides containing brodifacoum, bromadiolone, difethialone, or difenacoum are prohibited for use by anyone within the entire state.

These compounds are not anticoagulants. Unlike some other rat poisons, which require multiple days of feeding by an animal, bromadiolone can be lethal from one day's feeding. Nevertheless, rats showing some degree … Comparison of efficacy of second-generation anticoagulant rodenticides: Effect of active ingredients, type of formulation and commercial suppliers It is important to remember many companies produce more than one type of rodenticide. Chlorophacinone (7%) Difethialone . Incidence of prolonged prothrombin time in dogs following gastrointestinal decontamination for acute anticoagulant rodenticide ingestion. Other types have a wider margin of safety (e.g., bromadiolone) and it takes a larger amount to cause poisoning. This type of poison has a cumulative effect, so the rodents do not die instantly, but instead after a few days. CONTRAC Rodenticide, with the active ingredient, Bromadiolone, is a fresh tasting, highly compressed pelleted bait that holds up well, particularly in adverse or moist conditions. All the anticoagulants interfere with blood clotting, and death can result from excessive bleeding. With some types (e.g., brodifacoum), it only takes a very small amount to cause poisoning, especially in dogs. This group includes the second generation 4-hydroxycoumarins brodifacoum, bromadiolone, difenacoum, flocoumafen and the indanedione derivatives chlorophacinone and diphacinone. Chemical poisons: The most popular chemical rat poisons presently are Bromadiolone or Brodifacoum which is a powerful anticoagulant.

Bromadiolone is a rodenticide meant to kill rats and mice. Rats treated with difethialone or brodifacoum required 7 days to reach 100% mortality, while those treated with difenacoum or bromadiolone took 3 and 4 days longer, respectively (Table 1). Read more: Bromadiolone. Secondary poisoning in nontarget animal species from anticoagulants has also been documented. Other rodenticides that currently are registered to control mice include bromethalin, cholecalciferol and zinc phosphide. Brodifacoum is the most common active ingredient used and is usually found in 0.005% concentrations (D-Con Mouse Prufe II, Talon-G). As with all anticoagulants, accidental poisoning with brodifacoum can be antidoted with vitamin K1. Brodifacoum is a potent poison to all mammal species and it is essential that all baits are only used indoors and they must be well protected from non-target animals. Second-generation anticoagulants: brodifacoum, bromadiolone, difenacoum, and difethialone. Bromadiolone is found in brands such as Contrac, Maki, and Hawk.

Also, there are several days of feeding required. Nevertheless, rats showing some degree of resistance to brodifacoum have been found, although this is not thought to be of practical importance. Some of the poisons in this category include; brodifacoum and bromadiolone. For good results, the rats should eat the poisonous bait repeatedly. Bromadiolone was first registered in the United States in 1980. Some notable rodent killers are the Tomcat all-weather bait chunx, Tomcat rat and mouse bait, Tomcat rat killer II and Tomcat Mouse Killer III . The “second-generation” anticoagulants (brodifacoum, bromadiolone, difethiolone) are highly toxic to nontarget species (dogs, cats, livestock, or wildlife) after a single feeding. Three anticoagulant rodenticides, warfarin, bromadiolone and brodifacoum, were evaluated in the laboratory for their activity against the Indian field mouse, Mus booduga.In oral intubation studies M. booduga was found to be more susceptible to bromadiolone and brodifacoum than warfarin. brodifacoum, bromadiolone)_YL.docx Created Date: 9/20/2017 6:34:06 AM The brand offers different rat and mice poisons with most of them comprising active ingredients like diphacinone, bromethalin, and bromadiolone.

Made from an advanced formulation process, CONTRAC Rodenticide gets superior rodent acceptance and control, including control of Warfarin-resistant rats. Bromadiolone, Difethialone, Chlorophacinone, Diphacinone, and Brodifacoum are all anticoagulants. While the mechanism of all anticoagulants is similar, second-generation products (brodifacoum, bromadiolone, difenacoum and difethialone) are much more toxic and persistent, so they pose a much greater threat to non-target wildlife.
