HOMESTEAD, FL - SEPTEMBER 09: Stephen Jenner, from the Florida Department of Agriculture and Consumer Services, sprays an insecticide under an avocado tree where some Oriental fruit flies were found on September 9, 2015 in Homestead, Florida. The discovery of the flies has forced the state to quarantine about 85 square miles of farmland in Southern Miami-Dade county until they have been eradicated. The flies have the potential to damage Florida's $120 billion agriculture industry. (Photo by Joe Raedle/Getty Images)
