I had fruit flies and gnat flies in my home. Before I knew anything about getting rid of them, I noticed they loved my used coffee grounds that had been sitting in the brew chamber and coffee! I'd find them in the pot, drowned. Then I noticed they were getting down on my left over pancakes that had syrup on them that I'd sit by the sink until after I got dressed and started dishes.
So... I started putting my used coffee grounds in a pie plate or similar, patting them down and covering them with a thin layer of pancake syrup (enough to have an eighth of an inch over the grounds). They fell for it every time! They'd go for it and get stuck n the syrup and viola! This didnt eliminate the problem but it took out a huge porion if them. To eliminate, I had to do that, I put up ribbons over trash cans and put some store bought traps in and around my houseplants. Problem solved in about a week or so.
