Which of these is NOT a method of pesticide application?

The correct choice is that creams are not typically considered a method of pesticide application. Pesticide application methods are categorized based on how the pesticide is delivered to the target area or organism.

Aerosols are common for the delivery of pesticides, allowing for a fine mist that can settle on surfaces and penetrate hard-to-reach areas. Dust is another widely used application method, providing a way to coat surfaces or areas effectively and can be utilized where moisture control is necessary. Baits are strategically placed to attract and control pests, making them an effective method for targeting specific organisms.

In contrast, creams are not a standard method of pesticide application. While the term "cream" could refer to certain topical pest control products, especially in a veterinary context for pets, it does not fit within the common nomenclature of pesticide application techniques in pest control for agriculture or structural pest management. Thus, creams do not represent a recognized method used in pest management practices.
