This simple trap requires very little maintenance. Simply fill the traps with the non-toxic solution then leave them close to the problematic areas. The traps are clear so you can easily find out if they are effective at killing the gnats and fruit flies.
Buy a Gnat Trap
The easiest and most convenient of way of getting rid of gnats is by purchasing a reputable gnat trap. We highly recommend trying out the Gnat Stix for this purpose. Primarily designed to tackle fungus gnats, this particular product helps get rid of gnats by trapping them moments after they emerge from the soil. You will not have to rely on pesticide to get rid of gnats.
Vinegar Trap
This is usually the go-to method for people who want to rely on homemade techniques. For this method, you will need some apple cider vinegar, sugar, dish soap, water, and a container. In the container, mix two tablespoons of vinegar, 1 tablespoon of sugar, a few drops of soap, and 1 liter of water. Mix it well then place the container around the area where you see the most gnats. The insects get attracted to the smell of cider vinegar then succumb to their death when they touch the liquid mixture because of the soap. You may want to set up several small containers around the house to get a better idea of where the gnats are breeding.
