On game nights like UT versus Kansas, as many as 17,000 people pile into the Frank Erwin Center.
"It's probably twice the size the average town in Texas. So, just imagine your town, times two, in here for four hours," said John Graham with the Erwin Center.
They're coughing, sneezing and touching multiple surfaces.
It can be a breeding ground for dangerous microbes, but Graham says they've got the upper hand.
Graham added, "It's throughout the whole venue at some point in time, our suites, our restrooms, door handles, a lot of different surfaces that people may come in contact with."
It's called Germ Logic, by Pest Management Incorporated, an Austin-based company.
"We actually positively charge the molecule using this gun and what happens is...and when it touches a surface that is negatively charged, it sticks to it like a magnet," said Director of Operations, Brian Dicicco.
He says they saw a need for long-lasting protection against bacteria and viruses in businesses, schools, hospitals...and locker rooms.
Brian said, "Staph is actually starting to mutate. It can actually become tolerable to disinfectants...It electrocutes it...the staph particularly can't adapt to being electrocuted."
It destroys bacteria by making the molecules implode.
"It provides us kind of a sense of relief that we know it's there," said Graham.
Todd McElwee, with SOCO Pet Lounge added, "We've definitely noticed a reduction in our staff sick days. We haven't had any animal illnesses or sicknesses in the last year. This gives us a piece of mind also of something that's going to last longer than a day or two."
You can even use it on your own laundry. All you have to do is throw in your load, pour in two ounces of the antimicrobial and it will last for 100 washes.
"We love our disinfectants. We love our cleaners, but the problem is it doesn't last beyond the application. So, as soon as it's dry, a minute later, that surface is acceptable to certain types of bacterias, viruses," said Brian.
The antimicrobial lasts for 90 days.
Reps say testing has shown Germ Logic can combat Staph infections, the H1N1 virus and salmonella.
