Take back your backyard with the Burgess 1443 Propane Insecti Fogger: completely portable and lightweight, this propane-powered fogger is the most economical way to kill mosquitos and biting flies. The secret to its effectiveness lies in the microscopic particles it produces - up to seven times faster than mist. When applied before dusk or dawn, the fog drifts and penetrates deep into landscaped areas where mosquitos hide, killing on contact and creating a mosquito-free zone that lasts up to 6 hours. In about 5 minutes the fog dissipates, allowing you to enjoy the outdoors again. One treatment takes an average of 10 minutes to voer a 5, 000-square-foot yard, making it perfect use before backyard picnics, barbecues, outdoor parties, and special events. This is the same proven system used by professionals to kill mosquitos that may carry the Zika virus or West Nile Virus. The Burgess 1443 Propane Fogger features a 44oz reservoir and requires a standard propane cylinder (not included). A trigger lock helps prevent accidental dispensing of insecticide. For best results, use only with Black Flag, Cutter, or Repel branded Fogging Insecticides. For outdoor residential use only. | BURGESS Propane Insect Fogger | Size 44 oz
