I imagine it being like a sprinkler system, set on a timer, soap and rinse. Maybe a tech inspects the house/shrubbery once a year, tweaks according to growth/need. Everything is monitored online.
What makes it tough is the unpredictable mud dobber/wasps nests, random locations and takes more effort to clean off
So i don’t see it being too likely, unless there’s an insect repellent sprayed onto the house as well, that doesn’t get the widows dirty
