Use vinegar to kill bugs by mixing a solution and spraying bugs in the home and garden, and using it to create a fruit fly trap. Vinegar, when applied to surface areas, make the areas unappealing to bugs. While this doesn't kill them, it makes them go away.
- Mix vinegar solution
In a spray bottle, mix vinegar and water. A good ratio for a spray bottle is three parts water to one part vinegar. Add a teaspoon of liquid dish soap and shake. Spray the solution on pests in the home or in the garden.
- Repel with vinegar
Spay the vinegar solution on the surfaces around bugs to repel them. Rather than killing them, vinegar acts as a deterrent. Use this method to prevent new infestations after other vinegar solutions have eliminated the current pests.
- Make a heavy-duty mixture
Try heavy-duty bug fighter in the garden if the simple vinegar solution doesn't repel the bugs adequately. In two gallons of warm water, mix three tablespoons of baking soda, two tablespoons of vinegar, two tablespoons of liquid dish soap and two tablespoons of canola oil. Apply the solution to garden plants.
