There are many varieties of rodenticides, but they are usually classified as anticoagulants or non-anticoagulants. Anticoagulant rodenticides work by interfering with the blood clotting abilities of animals. After eating a lethal dose of poison, the animal dies from internal hemorrhagic complications. Non-anticoagulant rodenticides act in different ways and have toxic effects on different organs and to varying degrees. Anticoagulant rodenticides interfere with blood clotting, leading to uncontrollable bleeding leading to death. Supertoxic poisons include second-generation brodifacoum anticoagulants, bromadiolone, difethiaone and difenacoum, which are especially dangerous and persist for a long time in the tissues of the body. Predators and scavengers that feed on poisoned rodents are often poisoned by these slow-acting rodents. Although all anticoagulant rodenticides have a harmful impact on wildlife, SRGs such as difenacoum, brodifacoum, bromadiolone and diffethialone are particularly dangerous because they have a higher effectiveness than previous generations of poisons. A single dose has a half-life of more than 100 days in the liver of a rat. An effective rodent control strategy includes prevention through hygiene measures, methods of physical exclusion and a combination of effective methods of population control. In some cases, traps can be useful alternatives near homes, garages, and other structures. For example, small populations of house mice can be effectively managed with traps. It is important to always pay attention to non-target wildlife when conducting a fishing program.

Rodenticides still available in California for licensed pesticide applicators include first-generation anticoagulant rodenticides (warfarin, chlorophacinon, and diphacinon) and non-coagulant rodenticides (bromelain, cholecalciferol, and zinc phosphide). California`s Ecosystem Protection Act, drafted by Congressman Richard Bloom and co-authored by Senator Henry Stern and Congresswoman Laura Friedman, put in place safeguards for the use of the most toxic toxins to rats — second-generation anticoagulant rodenticides (RMGS) — except in a public health emergency until their re-evaluation by the Department of Pesticide Regulation determines: that they will not have a significant adverse effect on non-target wildlife species. “This sensible measure to better protect our wildlife from these dangerous rat poisons should be adopted across the country,” said Jonathan Evans, director of environmental health at the Centre for Biological Diversity. “When there are literally hundreds of safer and more cost-effective solutions on store shelves, there`s no reason to leave the worst of the worst poisons on the market.” To date, all rodenticides containing brodifacoum, bromadiolone, difethiaone or difenacoum are banned for general use in the State of California, with the exception of registered pest control experts. The use of these toxins in state parks, wildlife and protected areas is prohibited unless it is for agricultural purposes or by federal agencies. However, a 2018 analysis of 11 studies found that more than 85 percent of California`s mountain lions, bobcats, and Pacific fishermen were exposed to rodenticides. The California Department of Fish and Wildlife`s database of mountain lion deaths also revealed that anticoagulant rodenticides were found in the livers of 63 of the 68 mountain lions who died between 2015 and 2016. A recent state analysis conducted in late 2018 concluded that 85% of the surrounding wildlife, from mountain lions to bobcats to birds, was accidentally killed by these supertoxic rodenticides.

This, in turn, has led to further debate and reassessment of the bans and restrictions currently imposed on the use of second- and first-generation rodenticides in the state of California. The trap is powered by a CO2 cartridge and can hit 24 times without having to be reset. The pneumatic hammer immediately kills the animal and avoids unnecessary suffering. Best of all, the trap is not based on the use of poisons or other toxins. This is a great solution for those who want to protect their business or home from pests without using rodenticides. Second-generation anticoagulant rodenticides include: Rodenticides are very effective in fighting intruders and rodent infestations. The problem is that lethal efficacy is not limited to rats and mice. Secondary poisoning of wildlife, pets and humans is a growing problem. When rodents feed on toxic bait, two things happen to create unintentional exposure. Rodents often remove pieces of bait when feeding. This poison can then be distributed anywhere in the rodents` path, including in homes where children have access, in backyards where pets have access, or throughout the environment where other wildlife have access.

Anticoagulant rodenticides are persistent and can be detected in water, soil and even snails. Children and pets are particularly susceptible to rodenticide poisoning. Young children regularly consume poison intended for rodents, confusing bait with food. Similarly, pets consume bait directly or poisoned rodents.
