According to the American mosquito control association , mosquitoes are weak fliers and so can be easily kept away from the wind created by a simple box fan in your outdoor seating area. A fan will also disperse the carbon dioxide that you exhale and other odors that mosquitoes use to find their hosts. This is a much better method than using a general spray, which eliminates all insects, pests and beneficial alike, disrupting the ecology not only in your yard but also that of your neighbors.
