Homemade methods of fly control include setting traps for them, using pepper to kill them and using essential oils to deter them. Water-filled plastic bags also put off flies.
Pour heated apple cider vinegar in a jar, and punch some holes that can fit a fly on the lid, or place a funnel in the jar’s opening. Flies get in the jar and are unable to escape out. Substitute the apple cider vinegar with overripe fruit or wine.
Make a fly repellent using cloves and a lemon. Place cloves into a half cut lemon and place it on the dining table to keep off flies. Water in a plastic bag helps to put off flies because it distorts their vision.
Essential oils such as lavender and lemon grass repel flies. Put some lemongrass oil in a spray bottle, add some water, and spray around the house and on flies to chase them away.
Mix some cayenne pepper and water in a spray bottle, then spray around to kill flies. Since flies breed mostly in drains, pouring a mixture of vinegar and hot water down the drains destroys their breeding grounds and kills their larvae.
