Texas Pesticide Applicator Practice Exam

Why are poisonous baits often used in small amounts?

1. They are too potent for large areas

2. Pests gather only in specific locations

3. They are expensive to use

4. They have short shelf lives

The correct answer is: Pests gather only in specific locations

Poisonous baits are used in small amounts primarily because pests tend to congregate in specific locations. This localized application is advantageous for several reasons. When baits are strategically placed where pests are most active, it ensures that the toxic substance is effectively delivered to the target organisms while minimizing exposure to non-target species. Additionally, using smaller amounts reduces the risk of overexposure, which could lead to potential harm to beneficial wildlife or the environment. This practice is particularly important for maintaining an ecological balance and ensuring safety when controlling pest populations. The other options provided don't align with the primary reason for the small amounts of baits. While potency and expense can play a role in pest management strategies, and shelf life considerations may affect the practicality of using some products, the key factor remains the targeted nature of pest behavior and the effectiveness of localized treatment.
