I should also make it clear that I hate going to the store. Really hate it. The traffic to get there, the people there, and then there's the fact that I have to get dressed and brush my hair. I normally look like one of those poor people you see on an episode of hoarders or in the subway in DC.
So- here's my homemade cheap solution:
Apple cider vinegar. (ACV)
A mason jar (any size will do)
A small piece of plastic wrap big enough to cover the mouth of the jar.
A toothpick.
Pour some ACV in the mason jar. You could use any cup really, but I had a mason jar handy. You don't need a lot of ACV, maybe 1/2 to 1 inch in the jar. Anything more would just be a waste. (If you're using a small 4 oz. jelly jar, fill it half way.)
Stretch the plastic wrap over the top of the jar and press it down around the mouth of the jar. Press and seal works great for this step but really any plastic wrap will do. If your wrap won't stay in place you can secure it with a rubber band or even some tape around the mouth of the jar will hold it in place.
Use a toothpick to make a small hole, but large enough for the fruit flies to crawl in but not so big that they can fly back out easily.
After a few days you should notice that there are considerably less flies buzzing around your sink or fruit and floating in the ACV instead! You can place several of them in the kitchen or whereever your fruit flies are hanging out.
Hopefully this will help you out too, and save you a trip to the store!
