We have an infestation at work. There are 3 of us with the bumps and bites. Every time each one of us go to work, we have more bumps & bites. Once we get home, of course after cleaning we are fine. Our doctor from employee health suggested swimming in a chlorinated pool whenever we have the opportunity, which we have been doing nightly, where afterwards we bath with antibacterial soap & use anti bacterial hand sanitizer before putting the lotion on we were prescribed by employee health. They stated that they had environmental services come in and clean our office, but we are still getting bit...ONLY at work. WHat should we do? 
The DR thinks it's scabies and is treating it as such.
