Typical rat poison bait station (Germany, 2010) Rodenticides are chemicals made and sold for the purpose of killing rodents.While commonly referred to as "rat poison", rodenticides are also used to kill mice, woodchucks, chipmunks, porcupines, nutria, beavers, [1] and voles.
Tetramethylenedisulfotetramine (TETS) is an organic compound used as a rodenticide (rat poison). [2] It is an odorless, tasteless white powder that is slightly soluble in water, DMSO and acetone, and insoluble in methanol and ethanol. It is a sulfamide derivative. It can be synthesized by reacting sulfamide with formaldehyde solution in ...
Poison shyness, also called conditioned food aversion, is the avoidance of a toxic substance by an animal that has previously ingested that substance. Animals learn an association between stimulus characteristics, usually the taste or odor, of a toxic substance and the illness it produces; this allows them to detect and avoid the substance.
The aversion reduces consuming the same substance (or something that tastes similar) in the future, thus avoiding poisoning. Studies on conditioned taste aversion that involved irradiating rats were conducted in the 1950s by John Garcia, [1] leading to it sometimes being called the Garcia effect.

Rats are also associated with human dermatitis because they are frequently infested with blood feeding rodent mites such as the tropical rat mite (Ornithonyssus bacoti) and spiny rat mite (Laelaps echidnina), which will opportunistically bite and feed on humans, [57] where the condition is known as rat mite dermatitis.
Scientists hope that these human-rat transplants will help them study how genetic mutations influence brain circuits and affect how people behave. Rats' behavior changed after human tissue was ...
