Name a common pest that can be controlled by using rodenticides.

Rats are a common pest that can effectively be controlled using rodenticides. Rodenticides are specifically designed to target rodents, which include rats and mice, by utilizing potent chemicals that interfere with their physiology, ultimately leading to their death. These poisons work by either disrupting normal bodily functions or causing internal bleeding, which is particularly effective in managing rodent populations.

In contrast, flies, ants, and termites are not successfully managed with rodenticides. Flies are more effectively addressed through insecticides that target their life cycle and adult forms. Ants require baits or insecticides that can disrupt their foraging and colony behavior. Termites, which are wood-destroying insects, typically need treatments such as liquid termiticides or baiting systems designed to eliminate their colonies and protect structures from damage. Therefore, rodenticides specifically make sense for targeting rats as part of a rodent control strategy.
