What is the route of entry when a pest swallows pesticide?

When a pest swallows pesticide, the route of entry is through the mouth. This method of exposure occurs when the pest ingests the pesticide, allowing it to enter the digestive system. Pesticides designed for ingestion are formulated to be attractive to pests or are presented in bait form. Upon consumption, the active ingredients can affect the pest internally, leading to mortality or the intended control effect.

Understanding the route of entry is crucial for effective pest control, as it informs the choice of product and application method. This knowledge also helps in assessing the risks posed to non-target organisms, including humans and pets, who may come into contact with the pesticide.

In comparison, other routes such as breathing (inhalation), penetrating the skin (dermal exposure), and absorption all refer to different mechanisms of toxin entry that do not involve swallowing. These alternatives are generally relevant for particular formulations of pesticides or different pest types, but in the context of swallowing, the mouth is the pathway of entry.
