Two people were taken into custody Friday for allegedly selling carfentanyl out of a house in Southwest Miami-Dade.
Carfentanyl is another form of the synthetic opioid fentanyl, which is 10,000 times more potent than morphine.
The drug bust happened on southwest 171st Street and 104th Avenue.
Miami-Dade detectives say they have had their eyes on the lime green house for the last couple of months. Friday, the department's narcotics unit along with the FBI served a search warrant and made the discovery.
Police arrested Omega Demetrius DuPont, 45, and Tyree Sharon Tyson, 29, at the home. They face multiple drug charges.
Police say the couple has a history of breaking the law. Neighbors are upset the the deadly drug was being made in a lab just one block from Ethel Beckford-Richmond Elementary School.
Investigators say they uncovered other drugs and guns in the house. Footage showed officials wearing hazmat suits to investigate the drugs because fentanyl is so dangerous.
"As minimal as it may seem, it's still very hazardous so that's why they're dressed in gear to maintain they're safe," said Det. Dan Ferrin.
Officials say the highly sought-after fentanyl is more dangerous than flakka. Florida medical examiners reported a sharp increase in deaths related to fentanyl, especially in South Florida.
