1. A topical pests control application system comprising:
an active ingredient reservoir comprising an active ingredient preselected based on an active ingredient selection model;
a solvent reservoir comprising a solvent, wherein an acidity of the solvent is regulated at a predetermined pH value; and,
a foam generation unit coupled to the active ingredient reservoir and the solvent reservoir, and configured to generate a pest controlling foam at a foam generating orifice, wherein the foam generation unit comprises:
a variable speed pump coupled to the solvent reservoir configured to supply a mixture of the active ingredient and the solvent at a predetermined input pressure to the foam generating orifice, wherein a concentration of the active ingredient in the mixture is less than 0.005%; and,
a metering unit coupled to the active ingredient reservoir, wherein the metering unit comprises a flow controlling orifice configured to control an input flow rate of the active ingredient from the active ingredient reservoir to the foam generation unit, wherein:
the foam generating orifice comprises an input aperture and an output aperture; and,
the input aperture and the output aperture are selected as a function of a length of a hose connected at a proximal end to the foam generating orifice, the active ingredient, the acidity, the input flow rate, and the predetermined input pressure to generate a predetermined pressure drop between the input aperture and the output aperture, and a predetermined output pressure at a distal end of the hose, wherein the length of the hose is at least 100 feet, and the predetermined pressure drop is determined such that an output pressure at the output aperture is at least 900 psi, such that the pest controlling foam is generated with a minimum dwell time of at least 5 minutes posterior to application on a surface.
