This isn't a photo for me to brag about my tomatoes here in the South Window. Just to show the fruit fly trap. There is another one in the kitchen and they work wonders!
Fruit flies are also known as vinegar flies. Apple cider vinegar. For some reason, I began diluting it 50:50 with water maybe in a fit of parsimony, or because I didn't like smelling it so strongly, or to splash in to mix the drop of dishwashing soap.
Don't follow the instructions of poking holes in the plastic wrap with a toothpick. That idea was the only problem I had several years ago on the first try. I use a knife, just don't make the cuts very big. The flies won't be able to find their way out. Toothpick holes, they couldn't squeeze in and I thought it wasn't working.
If you want to release the flies outdoors rather than dumping their drowned bodies - you can use a jar with a mashed banana in the bottom and a cone of paper guiding them down to it. They won't find the small, low opening to the cone and won't find a way out. Problem I had with this trap was knocking the cone out of the jar and having the flies escape right back into the house!
