Navy Petty Officer 2nd Class Jessica Wright, a hospital corpsman and preventive medicine technician at Naval Branch Health Clinic Kingsville, Texas, checks the gas flow on a ‘mosquito magnet’ trap, July 11, 2018. The trap uses propane to create a carbon dioxide flow to attract mosquitoes into a mesh bag. The mosquitoes are then sent to a state laboratory to determine numbers by species and if any carry diseases such as the West Nile or Zika virus. Navy photo by Rod Hafemeister
