Which of the following is NOT a route of entry for pests?

The correct answer is that the eyes are typically not considered a standard route of entry for pests, unlike the other options listed. Pests, such as insects or rodents, primarily enter the human body through routes that facilitate their survival or the transmission of disease. Skin contact, inhalation, and ingestion are all viable mechanisms through which pests can affect human health or spread disease.

When pests come into contact with skin, they can cause irritation or transmit allergens and pathogens. Inhalation refers to the process where pest droppings or other contaminants can be inhaled, leading to respiratory issues. Ingestion occurs when individuals consume contaminated food or drink, which can carry harmful pests or their eggs.

The eyes, while they can be affected by pests, are not a primary point of entry in the same way. Instead, they may be exposed to irritants or allergens but do not serve as a significant route through which pests typically enter the body or cause harm. This distinction highlights the specific nature of how different pests interact with human physiology and the primary concerns regarding pest control and health risks.
