Rat poison baits include acute and chronic rodenticides, as well as sterilizing agents, added to baits favored by rodents. Besides standard poison baits, poison powders, pastes, and venom can also be prepared, and rodenticides can be sprayed on plants. The drugs used include chemical agents, botanicals, and antibiotics. Generally speaking, poison baits are effective, efficient, and low-cost; however, they can also cause toxicity, harm to non-target animals, and environmental pollution. Acute rodenticides (single-dose or fast-acting rodenticides) are typically effective after a single dose, while chronic rodenticides (multiple-dose or slow-acting rodenticides) require multiple doses for significant effects. The differences between these rodenticides are determined by their specific characteristics.
