While a small swarm of gnats might make you think that you might be in trouble and way over your head, you don’t always have to ask for the assistance of a trained professional. Gnats can be eliminated with the help of a gnat trap, which you can buy from stores, or make yourself.
For instance, a combination of vinegar and dish soap can make the perfect trap for gnats. They will come attracted by vinegar but will remain caught by the soap. Another method involves the use of a jar with rotten fruits in it. Commercial solutions are also recommended, especially when dealing with large swarms.
