How would you trap fruit flies so that you could feed them to foul (chickens,ducks, etc.) and fish?
How can I trap those insects _economically_ and then feed them to livestock? Chickens, duck, fish etc. would readily gobble the fruit flies up IF the flies weren't flying around... how would you capture lots of wild fruit flies?
I have been thinking about a trap that allows them to fly in but not fly out and then throwing the trap into a freezer to slow them down and then throwing them to the birds... but I'd like to find something that could be done entirely outdoors WITHOUT electricity. Ideas?
