What is the recommended air pressure for a crack and crevice treatment with a compressed air sprayer?

The recommended air pressure for a crack and crevice treatment with a compressed air sprayer is generally set at 3-5 PSI. This pressure range is optimal for ensuring that the pesticide formulation is delivered effectively into the cracks, crevices, and narrow spaces where pests may hide. At this pressure, the application can achieve a good balance between proper coverage and minimizing the risk of drift or oversaturation, which could lead to unwanted exposure or reduce the efficacy of the treatment.

Using a pressure that is too high could cause the pesticide to disperse too widely, resulting in areas that are either over-treated or under-treated, which can lead to ineffective pest control. Maintaining the air pressure within the 3-5 PSI range allows the applicator to control the flow of the pesticide more accurately, ensuring that it penetrates the targeted areas where pests are more likely to be found. This methodical approach increases the likelihood of achieving successful pest management while adhering to safety standards.
