Photo Cred Lisa Labute Alright! I know we should love all creatures of this earth but wow the fruit flies are brutal this time of year. And living in a building with no compost makes it challenging to say the least (don't even get me started on the composting issue!). But there is a quick solution, drill or hammer some holes in the top of a small mason jar. Add two tablespoons of apple cider vinegar (ACV) and voila! you have a very effective fruit fly trap. Sorry little guys.
