    I have hired other companies in the past to spray and disinfect our office and Bio-One of Dallas County is by far the best. Brent and Mandy Grigsby are really focus on providing great customer service. They use EPA approved surface-active agent, they are friendly and the team showed up with proper PPE. I definitely recommend them.
