text: I assume you mean flying gnats. I would use a bug spray. You can go to the store and buy a product called Off that you can spray yourself with and it will keep the bugs away. Just make sure you don't buy On by mistake. A friend of mine did that one time and he was covered in bugs inside ten seconds. Try not to wear dark clothing, they like dark clothing, and avoid being out in the grass during dusk when they are the most active, like with mosquitoes, very similar. There's also special candles you can burn that the smoke drives the bugs away. Unless you really did mean flying nets, which I've never heard of, in which case you could perhaps use fire to destroy the nets which should get rid of them.
