How do I did my home of fruit flies and/ or gnats?

Hi:
You may want to make a trap with apple cider vinegar and a drop or two of dishwashing liquid in the bottom of a clean jar. Make a small cone out of paper and place it over the jar with the small end up. It attracts them and then they have trouble getting back out again.

Here are two websites for you to read about getting rid of fruit flies. It works well for gnats as well.
