One way to kill flies without using spray is to make some traps using apple cider vinegar, a plastic sandwich bag and a cup. The trap works by luring the flies into the cup with the vinegar and using the plastic bag to prevent them from escaping.Continue Reading
To assemble the trap, pour about an inch of vinegar into a cup or glass. Cut the corner off of a sandwich bag. Place the bag over the opening of the cup so that the hole you cut is in the middle. Use a rubber band or some pieces of tape to secure the bag in place. Make one for each area where there is a fly problem. The flies will be attracted to the smell of the vinegar and will enter the trap through the opening, but will not be able to get out. Replace the vinegar once several flies have accumulated. After a few days, there should be a noticeable reduction in flies as long as you take steps to keep them from returning.
To prevent flies from coming back, install screens on windows and doors and take care to clean up messes around the house. Make sure to wipe up any spills right away and don't leave dirty dishes out. Flies are attracted to overripe fruit, garbage, standing water and food left uncovered.Learn more about Pest Control
