Lately I have found that the flies are always around the compost bin. Why would they not!? I got an idea the other morning as I opened the compost bin first thing and about 20 fruit flies flew out. Use the compost as a trap! No need for extra dishes trying to catch them!
All I do is leave the bin slightly open overnight. As we sleep the flies enter. First thing I do in the morning when I come to the kitchen is snap the compost lid closed, trapping the fruit flies. I take the bin right outside and empty it in my compost cart.
I have forgotten my plan once, and let the flies loose in the house. Oops!! I made myself a note, and for the kids to remember the plan.
