Flies can be attracted to certain substances that can be used to trap and kill them. Here are some common methods to attract and kill flies:

• Vinegar and dish soap: A mixture of apple cider vinegar and dish soap can be used to trap flies. The vinegar attracts the flies, while the dish soap causes them to sink and drown in the mixture.

• Sugar and soap: A mixture of sugar, dish soap, and water can also be used to trap and kill flies. The sugar attracts the flies, while the soap breaks down their cell walls and digestive tracts.

• Fly paper: Sticky strips of paper can be hung up to trap flies. When flies land on the paper, they get stuck and cannot escape.

• Soda bottle trap: A soda bottle can be turned into a trap by cutting off the top and inverting it into the bottom half. A mixture of sugar water and yeast can be added to the bottom half to attract flies, and the top half can be placed upside down on top of the bottom half. Flies will be attracted to the mixture and will fly into the trap, where they will drown.

• Plants: Certain plants, such as lavender, bay leaves, rosemary, cloves, and lemongrass, are known to repel flies. Essential oils or herbs can be used to create a scent that will keep flies away.

It is important to keep your home clean and free of rotting material, as flies are attracted to these substances. Proper sanitation and waste management can help prevent fly infestations.
