To maximize success, consider adding a teaspoon of sugar . Create a cone using a piece of scrap paper and tape, placing it at the mouth of the jar.

This funnel structure will be effective if not immersed in beer . Keep the trap near the fruit bowl or windowsill, or place it on the table while dining outdoors.

An outdoor fly trap

For those looking for an effective trap outdoors, the solution is simple. Take an empty plastic bottle, preferably one that contained milk or detergent , and rinse it thoroughly.

Next, pour half a glass of sugar into the bottle , add vinegar using a funnel and insert a whole banana peel. After shaking the bottle, place it in the desired location, whether in the garden or on the balcony.

If desired, you can even hang it. The scent of the mixture inside will attract all the insects inside. The powerful vinegar smell makes it a prime target for pesky flies. However,  Tea Tree , a natural insecticide, offers an effective alternative to repel both mosquitoes and flies.

Instead of using store-bought products, try creating a trap using a glass or jar. Combine red wine vinegar, eco-friendly dish soap and 5 drops of tea tree oil in the bottom of the container.

To make the trap accessible, cover the jar with a bag and pierce it in the center. For best results, add a teaspoon of honey , sugar or molasses.
