I have an knat problem in home office. The info you present appears to be focused on outdoor knat issues. Please advise.
In our Black Fly article, we have a section which features aerosols that are commonly used inside. The PT-565 can be used as a space spray when needed; a more permanent solution is to install an Aerosol Machine which runs on a time schedule you set so it will go off over and over without any intervention except to replace the Aerosol Refills. Either works great indoors.
