There are a lot of rats in the office how to disinfect a?

You can use UV lamps for daily disinfection, and you can also use an ozone machine! These have to be available at medical supply stores. If you don't have metal items you can also fumigate with lactic acid. You can also buy a sprayer to spray with dissolved chlorine sanitizer. Also wipe down tables and chairs with a disinfectant solution before you use them every day, and after work, put all the papers and mugs on the desk in the cooker so they don't get contaminated.
