If fruit flies are really bothering you, there are a few things to try. One is putting a few dots of dishwashing soap into a dispenser bottle and adding a bit of water. Squeeze the soap onto the dish towel then wipe it around the area you want to keep clean. That should stop them from coming near those spots again because they won’t like the smell- an added bonus is that it will make your kitchen or bathroom smell nice as well! You can also mix apple cider vinegar with water in a spray bottle and use it as fly oil for repelling insects- just be sure not to leave any standing liquid on surfaces so you don’t encourage more bugs!
