When possible, schedule activities to avoid the hours between dusk and dawn, which mosquitoes are most active. Dress in light colored, loose fitting clothing. Since mosquitoes are weak fliers the most effective means of keeping mosquitoes at bay is to use a large fan in the area you are inhabiting for a low-tech, environment-friendly solution. Use General Electric yellow “bug lights” bulbs, which are not a repellent, but do not attract mosquitoes like other incandescent lights. Citronella candles have a mild repellent effect, but do not offer significantly more protection than regular candles producing smoke.
