(CNN) -- A courthouse in Coral Gables, Florida, was evacuated Thursday afternoon after several employees reported feeling ill, fire officials said.
"There were approximately 40 employees in the building today when we took the call, and a total of seven have now been transported to area hospitals," said Hope Gibbs, division chief with the Coral Gables Fire Department. "We believe that this incident stemmed from pest extermination services that took place in the building earlier this week."
None of the patients lost consciousness, Gibbs said, adding that their conditions were not considered critical.
Nine units from the Coral Gables Fire Department and a total of 28 firefighters responded to the courthouse, she said.
