Georgia Pest Control Practice Test

What is one characteristic of fumigants?

1. They are a liquid at room temperature

2. They kill pests when absorbed through the skin or inhaled

3. They are only a threat to insects

4. They are used mainly for agricultural pests

The correct answer is: They kill pests when absorbed through the skin or inhaled

Fumigants are recognized for their ability to effectively penetrate various materials and organisms, which is crucial for pest control. One key characteristic is that they kill pests when absorbed through the skin or inhaled. This property makes fumigants particularly effective for controlling pests in enclosed environments, as they can easily disperse and reach hidden areas where pests might be residing. The mechanism of action involves the compounds being gaseous or volatile, allowing for exposure to both the dermal and respiratory systems of numerous pest species. The other options do not accurately reflect the nature of fumigants. While some fumigants may exist as a liquid at specific temperatures, they are typically gaseous during active application. Fumigants are not exclusively a threat to insects; they can also affect other organisms, including mammals, which underscores the importance of safety precautions during use. Furthermore, while fumigants can be used for agricultural pests, their application is not limited to just agriculture; they are also employed in structural pest control, food storage, and commodity treatment.
