Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison.In recent years, it has become one of the world's most widely used pesticides.It is typically used as a rodenticide, but is also used to control larger pests such as possums.
Both possums and rats are a serious threat to endemic invertebrates in New Zealand, where around 90 per cent of spiders and insects are endemic and have evolved without predatory mammals. [86] In a study on the diet of brushtail possums, 47.5 per cent of possum faeces examined between January 1979 and June 1983 contained invertebrates, mostly ...
Opossums eat insects, rodents, birds, eggs, frogs, plants, fruits and grain. Some species may eat the skeletal remains of rodents and roadkill animals to fulfill their calcium requirements. [ 45 ] In captivity, opossums will eat practically anything including dog and cat food, livestock fodder and discarded human food scraps and waste.
Zinc phosphide (Zn 3 P 2) is an inorganic chemical compound.It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. [5] Zn 3 P 2 is a II-V semiconductor with a direct band gap of 1.5 eV [6] and may have applications in photovoltaic cells. [7]
The common opossum (Didelphis marsupialis), also called the southern or black-eared opossum [2] or gambá, and sometimes called a possum, is a marsupial species living from the northeast of Mexico to Bolivia (reaching the coast of the South Pacific Ocean to the central coast of Peru), including Trinidad and Tobago and the Windwards in the Caribbean, [2] where it is called manicou.

Not all sources are serious.

[15] Alternative recipes for roadkill include raccoon kebabs, moose-and-squirrel meat balls, Pennsylvania possum pot pie and skunk skillet stew.
The chemical leavening effects were accomplished by the activating of a base such as baking soda in the presence of liquid(s) and an acid such as sour milk, vinegar, lemon juice, or cream of tartar. [24] Because these acidulants react with baking soda quickly, retention of gas bubbles was dependent on batter viscosity.
