How to get rid of flies around the house

I know that most of my posts are on plants, but one thing I found that was very useful in nearly eliminating the flies that got into the house were reusable fly traps. I bought them off eBay. They come with their own fly attractant, but there are many home-made recipes that should be able to work just as well. So far I am experimenting with pieces of meat, sugar, and vinegar to try and get the best mix.If you ever plan on buying these, it is important to get the reusable ones because the disposable one that I tried at the beginning filled up to maximum capacity of perhaps over 1000 flies within 3 days.

As the flies go into these traps, they don't seem to be smart enough to find their way out so they are bound to drown in the water below. Near the end of this 48 second video, a total of 2 flies enter this trap.
