Is there an easy homemade gnat trap?

Question:There are so many gnats in my room!! It's like I kill one, and another one appears the next five minutes after! Is there someway to attract them to one spot and then DESTROY them at the same time so they can't escape? Like sweet smelly sticky paper...something that I could make at home that would be easy. Please and thank you :)

Answers:
Pour 1/2" of cider vinegar into a bowl. Add a couple drops of unscented dish liquid soap. In a few hours you will see lots of drowned gnats.
