How to Kill Flies
- 1). Observe where the flies congregate. Place sticky fly traps in these areas whether they are inside or outside. Dispose of the old traps and replace them with new ones when the strips become too coated with flies.
- 2). Spray bug spray in outside areas where you will be spending time to preliminarily clear them of flies.
- 3). Arm yourself with fly swatter. When flies are in your vicinity stay very still and wait for them to land. As quickly as possible, swat the fly. Clean the mess, since it is unsanitary.
- 4). Create a homemade fly trap with a Mason jar by filling the bottom with syrup, sugar water, soda or any sugary substance. Poke holes in the top only big enough for flies to get in. The flies will crawl in for the sugary substance and not be able to get out.
- 5). Avoid having to resort to killing flies by keeping your area clean of waste. Put up screens and keep windows and doors closed.
