What characteristic is associated with aerosols as a disadvantage?

The characteristic associated with aerosols that presents a disadvantage is their difficulty in precise application. When using aerosol products, the dispersion of the formulation can be challenging to control, leading to overspray or unintended exposure to non-target areas. This lack of precision can result in decreased effectiveness of the pest control treatment, as the active ingredient may not adequately reach the intended surfaces or pests. Furthermore, the airborne particles can drift away in the wind or settle on unintended surfaces, causing potential environmental concerns or non-target harm.

The other options, while true in their own context, do not embody the specific challenging characteristic of aerosols that makes them less favorable in certain pest control scenarios. For example, low toxicity can be an advantage, high storage requirements are generally not true since aerosols can be compact, and very stable formulations tend to be an advantage as opposed to a disadvantage.
