Canned insecticides can be used in which of the following forms?

Canned insecticides are commonly available in aerosol form, which allows for the application of volumetric sprays. This method involves the release of pesticide in a spray pattern, making it effective for treating areas where insects may be present. The aerosol propellant pushes the insecticide out in a fine mist, enabling better coverage and penetration into crevices or hard-to-reach areas.

Other forms like liquid baits, dust formulations, and granular applications represent different types of insecticide delivery methods that typically do not utilize aerosol technology. For instance, liquid baits are designed to attract pests to ingest the pesticide, while dust formulations rely on a powdery substance that adheres to surfaces and pests. Granular applications involve particles that are spread onto surfaces or into the soil and are not applicable through a canned format. Therefore, the use of canned insecticides aligns specifically with volumetric spray applications, leveraging the aerosol delivery system for effective pest control.
