Which is NOT a type of pest that poisonous bait formulations are used to control?

Poisonous bait formulations are commonly used in pest control to effectively manage a variety of species, particularly those that are known for being problematic in domestic and commercial settings. Ants, slugs, rats, mice, beetles, and cockroaches are all pests that can be strategically targeted with these types of baits due to their feeding behaviors and susceptibility to various active ingredients used in the formulations.

Centipedes and millipedes, on the other hand, do not typically respond well to poisonous baits in the same way other pests do. These organisms have different feeding habits—they primarily feed on decaying organic matter or live prey (such as insects) and are not attracted to the bait formulations that are effective for other pests. Additionally, their ecological roles as decomposers mean that controlling them often requires different approaches, such as habitat modification or direct chemical treatments, rather than the use of bait.

Understanding the behavioral patterns and ecological roles of pests is crucial in pest management practices, which is why recognizing centipedes and millipedes as unsuitable targets for toxic baits reinforces the importance of selecting the right control method for specific pest types.
