What is the recommended pressure range for spraying fleas during indoor treatment?

The recommended pressure range for spraying fleas during indoor treatment is 7-10 psi. This range is effective because it allows for a fine mist application, which is crucial when targeting fleas and other small pests within indoor spaces. A lower pressure can lead to inadequate coverage or larger droplets, which may not penetrate the hiding spots where fleas reside, such as carpets, upholstery, and cracks in floors.

Using a pressure within this range helps to ensure that the insecticide is dispersed evenly and can effectively settle on surfaces where fleas are likely to live and breed, maximizing the treatment's effectiveness. It also minimizes the risk of over-saturation, which can occur at higher pressures, potentially leading to residue concerns and decreased efficacy of the treatment.

Higher pressures, like those suggested in some of the other options, may lead to a spray that is less controlled and more difficult to manage in indoor environments, increasing the likelihood of drifting product and unintended exposure.
