How can I get rid of gnats? I have tried vinegar.
If the gnats are on your body-I would either eat garlic bread (or any food with a lot of garlic in it) or use skin-so-soft (Avon) spray. They do not like either of these and will avoid biting on you.
At night use a low voltage light with a pan of water with a little dish washing soap in it. Put the pan as close to the light as you can.
