So, does white vinegar repel flies? No. Does it help in a roundabout, deceptive way? Yes. But only if you use it as a trap, not a spray.
If you’re looking for something to actually drive flies away, try essential oils like peppermint, eucalyptus, or citronella. Those have actual repellent properties backed by science. Vinegar is more of a “set it and forget it” decoy.
And honestly? I still keep a bottle under my sink. Why? Because it makes me feel like I’m doing something. Plus, it’s great for pickling onions while I plot my revenge on the tiny, winged overlords.
In the end, white vinegar is like that friend who shows up to your party with a bag of chips, eats half of them, and then leaves early. It’s not the hero you deserve, but it’s better than nothing. Just don’t expect it to save the day.
