After having a HORRIBLE time with flies last summer, I knew that I needed to be proactive this year. After using beertraps (which were pretty useless) I resorted to poison traps, but in the meantime I looked for other options.... and voila.... the maggot can!!!
It is working WONDERFULLY, I love to watch my chickens gobble those maggots up!!! I use wet cat food in mine and I refill it with fresh "bait" about once a week. There has been a drastic decrease in our fly numbers...proving that something nontoxic can really work!!! I haven't put poison fly traps out in a long while and don't plan on it ever again!!
Below is a picture of my maggot can and a link from BYC where I learned more about them.
