Now your homemade fly trap is finished and ready to use. Place it anywhere in your house (I suggest the kitchen since that’s where they seem to lurk) that’s out of reach of kids and pets. This DIY fly trap is safe for homes that have kids and pets since we have used organic materials that would not cause any harm, but it can still make a mess if disturbed. Plus, who wants a curious toddler taking a sip of fly juice? I think I just threw up in my mouth a little. 

Keep your trap out of reach on the kitchen counter if possible (make sure you’ve eliminated any old fruit from your kitchen and dining area, including from your compost pile, trash can, and garbage disposal). Alternatively, place it on top of your fridge.
