Rodenticides are substances used to kill rodents, including rats and mice. There are several synonyms for the word rodenticide, including rodent control products, mouse and rat poisons, pest control agents, vermin killers, and rodent extermination formulas. These products are often used in homes, businesses, and other areas where rodents may be present. However, it is important to use them with caution and only as directed, as they can be harmful to humans and pets as well. In some cases, non-toxic methods such as trapping and eliminating food sources may be more effective and safer for all involved.
