What is an example of a product that uses the impregnation method for pesticide application?

The impregnation method for pesticide application refers to the process of infusing a substrate with a pesticide to create a long-lasting controlled release product. Pest strips are a prime example of this method. These strips are often made from materials such as paper or plastic that have been impregnated with a pesticide, allowing for a gradual release into the surrounding environment.

This method is particularly useful in enclosed spaces, where the slow release of the pesticide can effectively control pest populations over an extended period without the need for frequent reapplication. Other products, such as liquid sprays, granular baits, and powdered dusts, do not utilize this particular impregnation technique; they typically involve direct application methods that do not provide the same prolonged efficacy as impregnated products. Thus, pest strips stand out as a unique application method within the context of pesticide delivery systems.
