Query: Definitely odorless but watch out for fruit flies

This countertop compost keeper is sleek-looking and definitely odor-free to the human nose. I was enjoying it immensely until I started seeing fruit flies in my kitchen. It takes us a couple of weeks to fill the compost keeper and during that time hundreds and hundreds of fruit flies had made it their home. I was so disgusted, I through the whole thing in the garbage.
